Adm6.book Page vi Thursday, May 6, 2004 10:06 AM
AdminiStor provides three security levels of user access rights allowing for
different levels of management from system administrators. The security access
can be configured uniquely for each different storage element.
Using push technology, AdminiStor eliminates network traffic typical of
polling-based systems. With its easy to use graphical interface, AdminiStor
eliminates the confusing views of SAN storage as seen from individual system
storage managers. And AdminiStor provides complete historical database
management of events for each managed storage sub-system.
Features
The following are major features of the AdminiStor Storage Management
software:
� Supports Java-enabled web browsers through a Java plug-in (Windows and
Solaris).
� Manage single or multiple imageRAID SCSI Series Storage Systems locally
or across the network providing higher availability.
� Complete RAID configuration capabilities.
� Automatic alert notifications are provided via “push” technology.
� Consolidated view of all nStor storage system within a workgroup,
department, or enterprise.
� User defined access to permit specific levels of access to specific users and
groups of user to the storage systems. This sets limitations to what levels of
user access control they may have to the specific storage systems.
� A historical database integration that maintains event logs, device
information, logging, and tracking/monitoring of all events and SNMP traps
in a JDBC-compliant database.
� Embedded private socket web server.
� Monitored notifications provided via SNMP traps and email.
� GUI interface with a industry standard tree-like display of components
familiar to most Windows users.

Introduction
Overview
Today, system administrators face many challenges in supporting a
heterogeneous network. A typical network environment has several computer
servers running different types of operating systems, storage systems, and
workstations. Monitoring these storage systems can be a very difficult task.
AdminiStor makes this task much easier. Now a centralized view of the storage
systems is available simply by using your favorite web browser and connecting
via the Internet or intranet.
AdminiStor has an enhanced package known as AdminiStor Plus that is designed
to monitor and manage imageRAID SCSI Series Storage Systems, from simple
single computer installations to complex networks and multiple Storage Area
Networks (SANs). In order to achieve this, AdminiStor Plus runs continuously on
selected systems connected to the storage, and coordinates the actions and
reporting among those systems.
There are three major sets of functionality. First is the AdminiStor Plus Host,
which connects to the storage either directly or remotely. Automatic monitoring
programs in these AdminiStor Plus Hosts check on the health of the storage
generating messages as needed, and provide the ability to adjust, configure, and
interact with the storage systems. All AdminiStor Plus Hosts, in a given customer
installation, can communicate with each other so their activities can be
coordinated. This allows AdminiStor Plus to greatly simplify complex storage
architectures, such as SANs.

Adm6.book Page 2 Thursday, May 6, 2004 10:06 AM
One of the AdminiStor Plus Hosts is selected to become the AdminiStor Plus
Server. The AdminiStor Plus Server is where all of the activities are coordinated, a
database of activity and status are kept, and the messages and notifications
originate. The AdminiStor Plus Server also includes a web server to enable access
by users and system administrators.
The AdminiStor Graphical User Interface (GUI) runs within the context of a
Netscape or Internet Explorer browser, meaning that the GUI is available
anywhere in the world where connections are allowed to the AdminiStor Plus
Server system. The AdminiStor GUI is where people can see the status of the
storage, change configurations, review and evaluate events that have happened
within the storage system, and perform operational tasks such as device
replacement and consistency checks.
AdminiStor supports any number of instances of GUIs, at any number of
locations, all running at the same time. There is no need to go to a dedicated
location, or worry about shutting down one AdminiStor GUI before another can
be used. During times when the AdminiStor GUI is normally not in use, the
AdminiStor Hosts communicate all problems and status changes to the
AdminiStor Server which can notify users through events placed in the system
log, Emailed to individuals, groups, or pagers, or send them via SNMP traps to
other management stations. This event notification can be customized to ensure
that only the changes of interest to the user are communicated. The AdminiStor
Hosts are on watch continuously 24 hours per day – seven days a week.
In a simple, single computer environment all of these modules will be located on
the same host computer system, and there is usually only one or two people that
will interact with AdminiStor Plus. These systems will be able to use a straight
forward installation without confusion.
In a modest SAN environment, several computers will be connected to the same
storage systems, perhaps with some parts shared among computers, and perhaps
with some parts exclusively assigned to certain computers. These systems will
benefit from the coordination accomplished by the AdminiStor Plus Server, by
collecting the information from the various computers running the AdminiStor
Plus Host and presenting a unified view of the storage. The status of shared
storage is presented as a single status, eliminating the confusion of various
computers each acting as if the shared storage were unique to that system.
Overview
Chapter 1 - Introduction
Adm6.book Page 3 Thursday, May 6, 2004 10:06 AM
In larger storage environments, there is a need to coordinate storage management
across the entire network, but there is also a requirement to delegate responsibility
for various subsets to different people. AdminiStor Plus allows storage domains to
be defined, each with a different password. Every module in the storage system
can be assigned to storage domains as needed and can belong to multiple
domains if desired. This means that a system administrator can have a single
password to access all storage assigned to his domain, no matter what computer
systems the storage is able to communicate with. This powerful capability allows
the system manager to grant limited access to storage management without
needing to expose full privileged access to any operating system.
In addition to defined storage domains, AdminiStor Plus has physical domains.
These reflect the reality that a system administrator with privileged access to a
computer has the need and the right to make changes to the storage components
available to that computer. All storage managed by AdminiStor Plus belongs to at
least one physical domain, defined by the AdminiStor Plus Host that can
communicate with that component. In the case of shared storage components,
they will belong to multiple physical domains, each defined by the AdminiStor
Plus Host that can access the storage.
The combination of physical domains, plus user defined domains, creates a rich
environment to support any system administration management structure desired.
Operating system administrators have the access they need to configure and
manage the storage they use, while storage administrators can effectively deal
with their storage, independent of the various computers using that storage.
AdminiStor Plus recognizes that not all storage management system users need to
perform the same tasks. Some users simply need to be able to evaluate the
current status, others must deal with maintenance issues, and selected individuals
will reconfigure and deploy the storage. There are three levels of access defined
for AdminiStor.
The first level is <Viewer>, where all aspects of the storage components can be
seen, but nothing can be changed. <Viewer> access is especially useful to allow
power users to see what is going on inside their systems, without opening the
system up to unexpected changes.

The second level is <Operator>, where actions needed to maintain storage can be
performed. This would include replacement of failed components and rebuilding
or checking redundancy information. No changes that would impact data
integrity or availability are allowed.
The highest level (third level) is <Administrator>, which allows full access to the
storage configuration. Only at this level can storage be reassigned, and data
impacted.
The three level privilege mechanism, combined with the physical and logical
domains, can support a wide variety of management styles over a range of
organizations. This ensures that AdminiStor Plus can grow with your company,
and adapt to the changes that are now a part of modern business reality. Yet all
of this comes in a package that is easy to install and use on a single computer.

AdminiStor Plus Host and Server
The AdminiStor Plus Host (ADM Host) provides the communication interface to
the AdminiStor Plus Server (ADM Server) for management and control of the hosts’
attached storage.
The AdminiStor Plus Server module is installed on a local host system. It has no
user interface and the storage system is accessed via the client GUI module using
a web browser. There will be at least one AdminiStor Plus Server in the
environment. It provides the communication interface to the AdminiStor GUI and
to each of the AdminiStor Plus Hosts. It may or may not have imageRAID SCSI
Series Storage Systems attached.
Events that occur are logged in AdminiStor Plus’s historical database which can
be reviewed at any time and can be integrated into a JDBC-compliant database.
If a storage system is shared among hosts, similar to what is found with a SAN,
the AdminiStor Host that finds the storage system first will “claim” ownership of
the system. When a subsequent AdminiStor Host(s) identify these already
“claimed” storage systems, they will mark them as passive devices and they
become the passive or redundant path owners. When you examine the tree
structure from the Client View window and you are logged in to a Domain that
has an AdminiStor Host which is a passive owner, you will notice the icons will
have a blue “P” overlaid on the icon of the redundant path devices. These icons
identify the passive devices and indicate that you are communicating through a
passive ADM Host to the primary owner ADM Host. If you are logged into a
Domain with a passive ADM Host, devices below the controller are not
displayed. You will still have management and control abilities from the passive
ADM Host through the active ADM Host.
If the primary AdminiStor Host owner of that storage fails, then one of the
passive AdminiStor Host will become the new owner of that storage. This is
determined by which passive ADM Host discovers the storage system first.
A result of this feature causes AdminiStor to be considered a fault tolerant
environment. Although, if the AdminiStor Server fails, the AdminiStor Server will
not be able to send messages to its established user’s. Each AdminiStor Host(s)
will continuously check to determine if the AdminiStor Server is alive, once that
occurs, they will once again communicate with each other normally.
AdminiStor Plus Host and Server 5
Chapter 1 - Introduction

Adm6.book Page 6 Thursday, May 6, 2004 10:06 AM
The level of fault tolerance is provided by the multiple path feature. The
AdminiStor Host that has ownership of the storage system is responsible for all
communication and management, and the redundant path or passive AdminiStor
Host(s) are waiting in the event the primary AdminiStor Host owner should go
down. If that occurs, the first AdminiStor Host to discover the storage system(s)
will become the new owner and the remaining AdminiStor Host(s) will remain
the passive redundant paths. When the AdminiStor Host that was the primary
owner comes back online, it will then become a passive owner.
Also, there is no particular order in which the AdminiStor Server and AdminiStor
Host are required to be started. Because of this feature should an AdminiStor
Server system go down, once it is back online communication will resume in a
normal fashion with the AdminiStor Host(s), as the ADM Host will continue to
poll until they locate the ADM Server. The same applies to the ADM Host, where
it will resume normal communication anytime it comes online.
AdminiStor GUI
The AdminiStor GUI provides the user interface allowing the ability to monitor,
configure, and manage your imageRAID SCSI Series Storage Systems. This
AdminiStor GUI runs from within a standard web browser installed on your
system.
The AdminiStor GUI module presents the overall system in a tree-like structure
that permits administrators or users to easily view the entire system, the status of
all components (e.g., controller cards, channels, drives, cabinet enclosures, fans,
temperature, and power supplies, etc.), and will launch the RAID Wizard to
configure imageRAID Controllers, as well as perform the LUN Mapping.
RAID Configuration Utility (RCU)
The AdminiStor RCU capabilities include a RAID Wizard, which allows automatic,
assisted, or manual configuration of the disk array hardware. This ensures that
the novice can have optimized storage, while the expert can set up the system to
the most exacting specifications.
Included with AdminiStor RCU is management of hot spares and component
replacement. Any failures within the imageRAID system can be dealt with easily
and effectively.
AdminiStor GUI
Chapter 1 - Introduction
Adm6.book Page 7 Thursday, May 6, 2004 10:06 AM
Monitoring
The most important ongoing function of AdminiStor Plus is its ability to monitor
the health and status of each storage system. Each disk drive is examined on a
periodic basis to check for acceptable soft error rates, and ensure that the data is
available to the AdminiStor Plus Host systems. Warnings are issued when
conditions are not good, and urgent messages are sent when there are failures
that impact data availability. The storage system imageRAID controllers are
checked for accessibility and health, and any problems are then reported. The
automatic error recovery performed by the imageRAID controllers is observed,
and urgent messages sent when automated recovery is not possible.
All of this monitoring is performed by the AdminiStor Plus Host, with the findings
forwarded to the AdminiStor Plus Server. The AdminiStor Plus Server is then
responsible for notifying the user in the appropriate manner. When an
AdminiStor GUI is displaying the status of the system, each storage component is
shown with a green, yellow, or red status indicator LED, showing if the
component is OK, has a recoverable problem, or is down. This allows the
AdminiStor GUI user to easily find the trouble spots in the storage system, and
drill down to the problem.
Notification
Problems and events within the storage systems are reported to any AdminiStor
GUI that has logged in to a domain containing that storage. An event log is
available, including historical events. This allows the AdminiStor GUI user to
easily see any global issues, such as loss of power in a section of the system, as
well as sequences of events which led up to a more serious problem.
Since problems with individual storage subsystems are normally rare, most of the
time there will not be any AdminiStor GUI observing the storage. AdminiStor Plus
can be configured to send events to the system error log, via Email to any valid
Email address, and via SNMP to other management systems. The events can be
selected such that only ones with the level of severity desired are sent out. Thus,
an Email enabled pager might receive all events, or just events indicating serious
problems. This is configured dynamically in the AdminiStor GUI, by those with
AdminiStor System <Administrator> access privileges. Refer to “E-mail
Preferences” on page 78 for detailed information and setup procedures.

Adm6.book Page 8 Thursday, May 6, 2004 10:06 AM
DataBase
AdminiStor Plus keeps a record of all events, along with the status of all storage
components, in a relational database. This is a Java Data Base Connectivity
(JDBC) compliant database, embedded as part of AdminiStor Plus.
The data stored here allows easy access to information about the operational
history of the storage system, as well as current details about each part.
AdminiStor Plus uses this to provide information to the AdminiStor GUI and
notification facility. The historical information kept here survives operating
system restarts, keeping that information available across any system disturbance.
The database is also where the AdminiStor Plus Server coordinates the
information coming in from the various AdminiStor Plus Hosts. This is the
method that lets AdminiStor Plus report on the actual storage elements, rather
than what might appear as multiple shared resources seen by various operating
systems.
Security and Encryption
The integrity and security of data communications between AdminiStor
components is ensured through the use of public key encryption techniques. In
order to avoid any issues with exporting to other countries, the data stream is not
encrypted, but a digital signature is exchanged. It is this digital signature that uses
public key encryption and since it is part of the standard Java distribution, there
are no export issues.
This means that it is possible to see all the data passing between AdminiStor
components (Server and Host), but it is not possible to change, add, or remove
any of that data. This prevents outside code from being able to join in to an
AdminiStor group.
Since the data is transmitted in the clear, AdminiStor uses a means to transmit
passwords in a manner in which they can not be intercepted and repeated from
another session. AdminiStor uses a public key encryption to create a digital
signature of any password, and verify on the basis of digital signature matching.
This key is unique for each GUI session, so a captured signature is not valid on
any other session, and therefore cannot be inserted into the data to gain access.
Only the signature is sent over the network, never the password itself.
DataBase
Chapter 1 - Introduction
Adm6.book Page 9 Thursday, May 6, 2004 10:06 AM
However, there is one area of vulnerability. When you create new passwords or
change an old password, the actual password must be sent to the AdminiStor
Server. It is required at the AdminiStor Server so the digital signature can be
generated for each GUI session. During this time any creation of passwords on
the GUI is open to possible capture.
Therefore, it is strongly recommended that new or changed passwords
operations be entered at the local host system GUI running on the same
computer as the AdminiStor Server. Using this method prevents the password
from being transmitted over the network. If the LAN connected to the AdminiStor
Server is considered secure, then a GUI on that LAN may be used. Any other
method is not considered secure and is a high risk.
SNMP Services
AdminiStor can be configured to send SNMP traps to any network management
system. These traps carry all the information that appears in the AdminiStor log
entries for all monitored storage device.
All SNMP traps will be sent from the AdminiStor Server, even if the event
originates in a storage system attached to an AdminiStor Host elsewhere.
Therefore, all of the host names and/or IP addresses given in the list of SNMP
managers are interpreted from the point of view of the AdminiStor Server system.
Refer to “SNMP Preferences” on page 81 for detailed information and setup
procedures.

11 Shut down your system, type shutdown -r now and press <Enter>.
12 Verify boot of the “HBA” driver by issuing the following command, type

13 If your kernel has not been configured to support multiple LUNs, then you
will need to recompile the 2.4.7-10 kernel to scan for multiple LUNs under
each target ID. Refer to “Modularized Kernel for Red Hat Version 7.2” on
page 38, below.
Modularized Kernel for Red Hat Version 7.2
The following steps will guide you through building a custom kernel for the x86
architecture.
NOTE: This example uses kernel version 2.4.7-10. Your kernel might be
different. To determine the kernel version you have, type the command
uname -r and press <Enter>. If necessary replace 2.4.7-10 with your
kernel version.
1 You must have both the kernel-headers and kernel-source packages installed.
Issue the following command, type rpm -q kernel-headers and press
<Enter> and rpm -q kernel-source and press <Enter>.
This will determine the versions, if they are installed. If they are not installed,
you will need to install them from the Red Hat Linux CD 1 or the Red Hat
FTP site (ftp://ftp.redhat.com).
2 At the shell prompt, change to the directory from which all commands are to
be issued, type cd /usr/src/linux-2.4.7-10 and press <Enter>.
3 It is important that you begin a kernel build with the source tree in a known
condition. Therefore, it is recommended that you begin with the command,
make mrproper.
This will remove any configuration files along with the remains of any
previous builds that may be scattered around the source tree.

4 Red Hat supplies configuration templates appropriate for different processor
configurations. Copy the configuration template which is correct for your
hardware. For example, type cp -p configs/kernel-2.4.7-i686.config
arch/i386/defconfig and press <Enter>.
5 Create an initial “.config” file from which to start, type make oldconfig and
press <Enter>.
6 Customize the “.config” file, type make xconfig and press <Enter>.
This will bring up a window, from which you will click on “SCSI Support.”
7 Change “Probe all LUNs on each SCSI device” to Yes.
8 Click on “Main Menu.”
9 Click on “Save and Exit.”
10 Click on “OK,” if prompted.
11 Edit “/usr/src/linux-2.4.7-10/Makefile” and modify the line beginning with
EXTRAVERSION = to create a “unique” kernel version by appending the date
to the end of the string. For example, if you are compiling kernel version
2.4.7-10, you can append the flag to look similar to EXTRAVERSION =
-10-nstor). This will allow you to have the old working kernel and the new
kernel, version 2.4.7-10-nstor, on your system at the same time.
12 After modifying and saving the “/usr/src/linux-2.4.7-10/.config” file, set up all
of the dependencies by typing the command make dep and press <Enter>.
13 Compile the new kernel by typing the command make bzImage and press
<Enter>.
14 Compile the kernel modules by typing the command make modules and
press <Enter>.
15 Install the new kernel to the /boot directory by typing the command cp /usr/src/linux-2.4.7-10/arch/i386/boot/bzImage
/boot/vmlinuz-2.4.7-10-nstor and press <Enter>.
16 Install the new kernel modules (even if you didn’t build one) by typing the
command make modules_install and press <Enter>.
Make sure that you enter the underscore (_). This will install the kernel
modules into the directory path /lib/modules/ using the path name that was
specified in the Makefile. Our example would be /lib/modules/2.4.7-10-nstor/.

17 If you have a SCSI adapter and you made your SCSI driver modular, you will
need to build a new initial ramdisk image by typing the command mkinitrd
/boot/qlanstor-multilun.img 2.4.7-10-nstor and press <Enter>.
NOTE: There are few practical reasons to make the SCSI driver modular in a
custom kernel.
18 Save a copy of the symbol table to the new kernel by typing the command cp /usr/src/linux-2.4.7-10/System.map /boot/System.map-2.4.7-10-nstor
and press <Enter>.
19 Keep a copy of the configuration file used to create the new kernel by typing
the command cp /usr/src/linux-2.4.7-10/.config /boot/config-2.4.7-10-nstor
and press <Enter>.
20 In order to provide a redundant boot source which protects from a possible
error in a new kernel, you should keep the original kernel available.
Depending on which loader you are using, this can be accomplished by
either updating the /boot/grub/grub.conf file or the /etc/lilo.conf file.
21 If you are using GRUB, skip to step 27.
22 Use a text editor to add your new kernel to LILO. Copy the following lines to
the new one and modify it to boot your new kernel image (and initrd image
if you have any SCSI devices and created an initrd image). Also, rename the
label of the old kernel to something such as “linux-old.”

Session Menu
From this menu you may select from the available options: “Establish,” “Shutdown,” or “Terminate Requests.” The Establish option performs the necessary task of making a connection to the AdminiStor Server. The Disconnect option closes off the connection with the AdminiStor Server. The Terminate Requests option allows you to stop all commands that have been submitted.
Session Menu
Domains Menu
From this menu you can access and log into the AdminiStor Host(s) physical and logical domains. You are provided the options to Open a connection to a specific domain (or a local system), open a connection to one of the Alive or All Known Physical Domains, refresh the current display, or Select All open domains. You can also Close, or Modify a domain, or Edit the names of the open domains.
NOTE: Only the Open menu choice is available with AdminiStor RCU.
Domains Menu
The physical domain consist of a host system and it’s devices (i.e., host computer, controller, physical disks, enclosures, channels, logical drives (LUNs), etc.). It is the physical components that compose the host system.
The logical domain comprise a mixture of the physical attributes of the physical domains and can include components of other previously created logical domains. Once you have logged into the physical domains, you can create a logical domain by choosing components of those physical domains which will be contained in the logical domain. This allows the user the ability to create customized domains by creating and performing a single login for a specific logical domain.
Session Menu
Chapter 3 - Startup & Navigation
Adm6.book Page 57 Thursday, May 6, 2004 10:06 AM
Rather than having to log into each physical domain which could be numerous
depending on the size and number of the topology of storage within the user’s
environment. These logical domains may or may not contain a subset of the
components of the physical domain, and allows the administrator the ability to
grant access privileges only to that subset.
This is a very powerful feature of AdminiStor Plus which allows the administrator to
customize and manage storage and user access to the storage.
For example; the user could log into several physical domains then pick disks from
one physical domain, and/or disks from another physical domain, selected
controllers, and logical drives and then create a new logical domain. Once created
then the login becomes necessary for the logical domain thus providing a view and
access to all of those physical domain devices. You can also specify the type of
access of that logical domain (<Viewer>, <Operator>, and <Administrator>) and
create additional logical domains from the original logical domain. The maximum
access level is only available to the access rights you have logged in with and
cannot be greater. This means that if you log in as an <Operator> you can only
grant <Viewer> or <Operator> access, not <Administrator>, since you were only
logged in as <Operator>. Refer to “Domains” on page 167.
Notification Menu
NOTE: These Notification options are enabled only for AdminiStor Plus
installations and are not available in AdminiStor RCU.
The Notification Menu provides the administrator or user’s with administrator
access rights the ability to setup recipients of Email notifications.
Notification Email Setup Menu
The Setup sub-menu provides the option to setup Email recipients.
To configure AdminiStor for E-mail services and SNMP traps, you will need to log
into the system as “admin” and access the Preferences option. From here you can
select the E-mail or SNMP tabs, and complete the necessary fields. Refer to
“E-mail Setup and Configuration” on page 77.

Passive Ownership (Redundant Path)
As described in the Introduction chapter, each AdminiStor Host will perform a
discovery of the storage systems and the AdminiStor Host which is first to identify
the storage system will take ownership of that storage system. The other
subsequent AdminiStor Host(s) will display the icons representing the storage
systems owned by the primary or active AdminiStor Host with a blue “P”
overlaid. This indicates it has a redundant path to the storage system besides the
AdminiStor Host you are logged into. Should the AdminiStor Host which has
ownership shutdown or experience a failure, the other AdminiStor Host(s) will
poll and identify the storage systems providing a redundant path. Again, the first
AdminiStor Host to identify the storage system will become the new owner.
If you are logged in with the appropriate access rights to an AdminiStor Host that
is a passive path, you will still have full access to manage and configure that
storage. However, you will be accessing the storage system through the primary
path of the AdminiStor Host that has primary or active ownership.

SNMP Preferences
AdminiStor can be configured to send SNMP traps to any number of network
management systems (NMS). These SNMP traps carry all of the information that
appears in the AdminiStor log entries for all the monitored storage systems and
their components.
All SNMP traps are sent from the AdminiStor Server regardless of where the event
originated. Therefore, all of the AdminiStor Host names and/or IP addresses
given in the list of SNMP managers are interpreted from the point of view of the
server system.
NOTE: All SNMP traps are sent with the community value “public” using the
UDP protocol and directed to port 162. If these values do not work in
your environment, please contact technical support for special
instructions to change these values.
The SNMP configuration can be set with a severity level, and no traps will be sent
for messages that are lower than a specified level. The severity level is used to
derive the specific trap number that will be sent to the network manager. Every
SNMP trap is associated with the nStor enterprise (.1.3.6.1..4.1.1793) and
references the nStor.administor.admTrap.admTrapInfo object
(.1.3.6.1.4.1.1793.2.1.1). The traps are all enterprise specific, with specific trap
numbers as defined in the following table.
reportOK 9984 The log entry is reporting that the situation is normal.
reportINFO 9985 The log entry is reporting some information that may be of interest, but does not require immediate attention.
reportWARNING 9986 The log entry is giving a warning of minor problems or the potential for an error.
reportERROR 9987 This reports a problem that is serious, and often means loss of redundant capability.

Adm6.book Page 82 Thursday, May 6, 2004 10:06 AM
Along with every trap is message text that defines the exact problem. This is sent
as ASN.1 (Abstract Syntax Notation One) type “Octet String” (4) as defined in
ISO/IS 8824 and ISO/IS 8825 and may be up to 440 characters in length. This
message is in the same language as used by Email notification, and has the same
contents. In order to make the message more useful in network manager
environments, multiple spaces are compressed to a single space, and multiple
lines are joined into a single line.
Most users would configure their network manager to respond to AdminiStor
traps by launching a browser and pointing it at the AdminiStor Server. This allows
the administrator to investigate and further deal with the problem reported.
To configure the SNMP Notification system:
1 Log in to your AdminiStor Server using the Domain ID “admin.” Do this by
clicking on the Domains menu and choosing Open.
2 Enter the Domain ID “admin” (case sensitive) or the name you choose to

Introduction
This chapter will provide information on how to use the RCU component of
AdminiStor to configure the imageRAID SCSI Controller (JSS122). These
controllers are referred to as the “imageRAID Controller” for the Ultra160-
to-Ultra160 models (JSS122).
Configuration activities involve some of the following:
� Setting up the controller options
� Creating logical arrays and partitions
Other activities that are accomplished through the RCU component are:
� Managing specific tasks and controller parameters
� Modifying existing logical arrays or partitions
� Deleting logical arrays or partitions
� Modifying array capacity by adding drives to the logical array.
NOTE: During configuration, some RAID Wizard screens will have a “Notes”
section appear in the window to assist you with any question you may
have relevant to the object selected. The screen captures in this chapter
have those note sections removed for printing layout purposes.

battery was configured as new or a specific age set in the Flash Utility.
(Note that you can move a battery from one controller to another, and a
feature in the Flash Utility allows you to set the existing number of
months already accumulated on the battery being installed. For example
if the battery had been used for 12 months in another controller and it is
a 36 month battery, when you install it in a different controller, you
would use the Flash Utility to set its age at 12 months. Then with each
new month, based on the computer systems’ date/time, the monitor will
increment the age of the battery accordingly.

External Target ID Control – Check to enable and uncheck to disable.
This allows the external enclosure to provide the SCSI target ID.
Environmental Temperature Enable – Check to enable. This option
allows the controller’s temperature information to be sent to the
environmentals package.
Environmental Auto Slot Flags – Check to enable and uncheck to disable.
This option allows the “slot flags,” which controls whether the controller
sends commands to the SEP to update the status of each enclosure slot.
The default setting should be enabled.
Environmental Global Slot Flags – Check to enable and uncheck to
disable. This option determines whether the controller sends commands
to the SEP to update the overall status of the enclosure.
Disable Battery Option – Check to disable. This option allows the user to
disable the battery condition monitor which also puts the controller in
write-back mode. If you have a backup battery pack in your controller,
you will see a notification when its life time has expired. (Refer to the
Environmentals tab to view the current age of the battery.) If you do not
have a battery pack installed you will also receive a notification for that
condition. If you do not have a backup battery installed and wish to
eliminate the alarm, you can disable the battery option. The default
setting is enabled (unchecked).
If you have replaced a battery you will need to reset the Battery Age
and Life monitor. This operation is accomplished through the VT-100
terminal using the Flash Utility. Refer to Chapter 5 of the VT-100
Software Guide for imageRAID SCSI Controller and follow the
procedures described. This process requires that you have a VT-100
terminal (or emulation) connected to one of the controller RS-232
ports.
Alarm Mute – Check to enable and uncheck to disable. An audible alarm
sounds when the controller becomes too hot, detects low or high
voltage, or an array becomes critical or offline. Changing the mute setting
lets you turn off the alarm when it is sounding. You should turn it back
on after resolving the problem causing the alarm.

Cache Lock – Check to enable and uncheck to disable. You can prevent
host systems from using SCSI mode select commands to change the
controller’s write-back cache setting. Some operating systems disable
write cache. If cache lock is enabled, the host cannot modify the cache
setting. The default setting is disabled (unchecked).
Operating Mode – Click the pull-down menu to select the appropriate
operating mode. You can change controller’s operating mode:
Stand-Alone Single Port, Stand-Alone Dual Port, Active-Active Single Port,
Active-Active Dual Port, and Active-Passive Dual Port. If you are using a
dual configuration (Active-Active/Active-Passive) a change to either
controller’s setting is immediately sent to the other controller, unless you
change to a Stand-Alone mode.
Operating Mode Models Available Description
Stand-Alone Dual Port
JSS122 This option allows the controller to operate with two host ports. In this mode, the same LUNs display on the two separate host ports. Stand-Alone Dual Port mode allows the host to achieve greater throughput by balancing I/O operations across the two host ports. Host port fault tolerance is also achieved, because the host can continue to access the controller if one host channel fails.
Stand-Alone Single Port
JSS122 This option allows the controller to operate with one host port and three or four disk channels. Select Stand-Alone Single Port mode if you do not want to run in dual port mode, or your host operating system does not support it
Active-Active Single Port
JSS122 This option allows both controllers to operate independently and as in an active-active pair. Active-Active modes allow two controllers to cooperate in system operation in a fault-tolerant manner. If one controller fails while in Active-Active mode, the other controller assumes its activities, allowing host access to continue.
When both controllers are online, each controller presents its LUNs on only one port.
Active-Passive Dual Port
JSS122 This option allows you to use just one controller with the second controller acting only as a backup in case of a failure of the controller in use.
When you change to this mode on one controller, you must reboot both controllers at the same time. After rebooting, both controllers will automatically be in Active-Passive Dual Port mode.

NOTE: You must reboot the controller for these changes to take effect.
Internal Hubs – This feature allows the user to enable (checked) or
disable (unchecked) the internal hubs. When enabled, the internal hubs
provide built-in connections for up to four (4) independent hosts. The
internal hubs replace the requirement for an external hub.
Environmental Poll Interval – This is the time interval, in seconds, that
the controller polls the SEPs for changes in status. The default setting is 5
seconds.
Create Array Backoff Percent – This setting backs off or reduces the
capacity of the array by the given percentage. The backoff percentage
helps when you assign spares by compensating for minor capacity
differences that occur between drive vendors. The default setting is 1%.
Drive Write Back Cache – You can control the write-back cache setting
for all of your disk drives at once. Changes take effect after the next
rescan or reboot. This can be set to “Enable,” “Disable,” or “Don’t
Modify.” The default setting is “Don’t Modify.”
Drive Smart – You can enable or disable the ability to change the
Self-Monitoring, Analysis and Reporting Technology (SMART) settings for
all drives connected to the controller. this can be set to “Enable,”
“Disable,” or “Don’t Modify (which means the controller should not
change any drive’s SMART settings.) The default setting is “Don’t
Modify.”
Utility Priority – You can change the priority at which all utilities (Verify,
Reconstruct, Expand, Initialize, etc.) run when there are active I/O
operations competing for the controller’s CPU time. The choices are:
High (default), Medium, and Low.
Dynamic Spare Rescan Rate – This tells the controller how often it should
look for an available drive by rescanning the bus. Remember that
rescanning the bus frequently can affect performance. If you have a SEP,
the dynamic spare configuration will not rescan the bus. The SEP will
detect the new drive and tell the controller to rescan; the rescan rate you
set here will not affect the system. Adjust the slider control to set the
rescan rate in minutes.

Running RAID Wizard
RAID Wizard is the AdminiStor GUI “assistant” for setting up, configuring, and
modifying new and existing logical arrays.
Drive Requirements for Specific RAID Levels
You can create an array at anytime. The table below describes the drive
requirements for each RAID level.
NOTE: Before you create more than one array, you must be sure that your host
operating system supports multiple Logical Unit Numbers (LUNs). Most
operating systems do, or have an option you can enable to support
multiple LUNs. If your operating system does not support multiple LUNs,
the host will only be able to see one array at LUN 0.
Before you create an array, you must decide whether you want to partition the
array. You can create an array one of two ways:
� Single-partition array – an array that stores all data in a single partition and
is accessed by a single LUN.
� Multiple-partition array – an array that can has more than one partition,
where each partition is assigned its own LUN.
NOTE: You must create at least one partition before using the array.

WARNING: Selecting a new configuration in either configuration mode
(Automatic, Assisted, or Manual), will delete the current
configuration and all data will be lost. To add another array to
existing configurations, choose Edit Configuration.
The configuration is a file that contains all the information about the
logical arrays, partitions, and controller parameters. Selecting New
Configuration will delete the contents of this file.
The selection New Configuration should only be used on a new
installation or when all existing arrays and partitions are no longer

Automatic Configuration
The Automatic Configuration option allows the RAID Wizard to automatically
create an optimum configuration based on the number of available drives. The
automatic configuration feature uses the maximum number of drives for the
auto-selected RAID level, and the full capacity of the drives to provide a fault
tolerant RAID level when able. The process creates at least one hot spare drive
for every eight (8) drives used. If the maximum number of drives for the RAID
level is reached, then a second array is automatically created if more drives are
available. The number of logical drives created is dependent on the total number
of physical drives discovered and the maximum number allowable.
To Start an Automatic New Configuration:
1 Sign on to the Administor Server, refer to “Signing On to a Domain” on
page 52.
2 Click on the Session menu and choose Client View, then select Logical.
3 Start the RAID Wizard, double-click the Controller icon that you wish to

The Assisted Configuration through the RAID Wizard walks the user through a
series of screen prompts to perform an optimum configuration. The user is
prompted to set options such as High Availability, RAID levels, Access and
Number of Arrays, and Optimization. The Assisted Configuration uses the
maximum number of drives for the selected RAID level, and the full capacity of
the drives to provide a fault tolerant RAID level when able. If the maximum
number of drives for the RAID level is reached, then a second array is
automatically created if more drives are available. Remember the New
Configuration option sets up a new configuration file which deletes any previous

Expanding Array Capacity
You can expand array capacity without stopping I/O activity, so you can
continue using the array while the expansion process runs. You can only expand
one array at a time.
NOTE: Expanding an array does not change the size of the host operating system
partitions that reside on the array, this is due to our controller working at
the block level not the file system level of the operating system. To use
the new space, you must create a new partition using the newly added
space or use a third-party application specific to the operating system to
change the partition size.
How you create a new partition or resize an existing one depends upon
the operating system. Most operating systems cannot resize an existing
partition. Refer to your operating system documentation.
The number of drives you can add to an array depends upon the RAID level as
shown in the table on the following page. You also cannot exceed the maximum
number of drives for each RAID level.
NOTE: When expanding a RAID 50 array, you must choose the exact number of
drives in the RAID 5 array that comprise the RAID 50 array. Example: if
your RAID 5 array contains three (3) drives, you must choose a total of
three (3) drives to perform the expansion. Choosing a different number of
drives, greater or less than, will cause the expansion operation to fail.
Drive Additions by RAID Level
RAID Level Number of Drives You Can Add Maximum Number of Drives
RAID 0 1 to 4 at a time up to the maximum. 16
RAID 1 (mirrored) Cannot expand N/A
Volume Cannot expand N/A
RAID 10 2 or 4 at a time up to the maximum. 16
RAID 3, 4, or 5 1 to 4 at a time up to the maximum. 16
RAID 50 All RAID 5 arrays must contain the same number of drives. You must choose the exact number of drives in the RAID 5 array to perform the expansion. Choosing a number of drives that are different from the RAID 5 array will cause the expansion to fail.

If you are expanding a multiple-partition array, you add free space at the end of

expand function may take an hour or more to complete, depending on the array
type, array size, drive speed, and other processes running on the controller.
Increasing the Capacity (Expanding Array Size or Expanding Partition Size)
You can expand an existing array by adding additional drives to the array thus

To Expand the Partition:
When you choose to expand a partition, the free space must occur directly after
the partition you wish to expand. When you select the Disk(s) item and add
drive(s), the “free space” will always occur after the last partition. So only the last
partition can be expanded. However, if a partition that is not last in the list must
be expanded, then you must delete all the remaining partitions first before adding
the new drives. This will cause the “free space” to occur after the desired partition.
WARNING: If you delete a partition, you will lose the data on that partition.
Therefore, in order to preserve any data on partitions that must be
deleted, copy that data to another drive or back up the data, then
delete the partitions, perform the expansion and recreate the
partitions from a portion of the new free space.

controller. Changing ownership allows you to continue using an array without
interruption and makes the array visible on the controller you change it to. You
can no longer see the array on the original controller that owned the array.
NOTE: When you change the ownership of an array, the LUNs assigned to the
array’s partition become invalid. After changing ownership, you must
assign a new LUN to each array partition.
To change array ownership:
1 Sign on to the Administor Server, refer to “Signing On to a Domain” on
page 52.

Trusting an Array
You can use the Trust Array function to bring an array back online by
re-synchronizing the time and date stamp and any other metadata on a bad disk.
This makes the disk an active member of the array again. You might need to do
this when:
� One or more disks of an array start up more slowly or were powered on
after the rest of the disks in the array. This causes the date and time stamps
to differ, which the controller interprets as a problem with the “late” disks.
In this case, the array will function normally after using Trust Array.
� An array is offline because a drive is failing, you have no data backup, and
you want to try to recover the data from the array. In this case, the Trust
Array function may work, but only as long as the failing drive continues to
operate.
Before you can use this function, your array must be offline. When the array is
offline the “Trust Array” button becomes active.
CAUTION: It is highly recommended that you immediately backup your data
when the array is brought online using the Trust Array feature.
Afterwards, you can troubleshoot the problem through the log files.
WARNING: The Trust Array feature can cause unstable operations and data loss
if used improperly. This allows possible corrupt data to be seen by
the host system. This feature is intended for disaster recovery.
To trust an array:
1 Sign on to the Administor Server, refer to “Signing On to a Domain” on
page 52.
2 Click on the Session menu and choose Client View, then select Logical.

Changing the Operating Mode
You can change the controller’s operating mode: In a dual controller configuration
(Active-Active or Active-Passive mode), a change to either controller’s setting is
immediately sent to the other controller, unless you change to a Stand-Alone mode.
CAUTION: When using any dual port mode, the host operating system and
drivers must support dual port accesses. If the host system does not
support dual port access, do not configure the controller in dual port
mode, because the operating system may believe that a single LUN is
really two independent arrays, resulting in possible data corruption.
Host Channel Setting Description
Stand-Alone Single Port This option allows the controller to operate as one of two controllers in an Active-Active pair. Active-Active mode allows two controllers to cooperate in system operation in a fault-tolerant manner. If one controller fails while in Active-Active mode, the other controller assumes its activities, allowing host access to continue.
Stand-Alone Dual Port This option allows the controller to operate with two host ports. In this mode, the same LUNs display on the two separate host ports. Stand-Alone Dual Port mode allows the host to achieve greater throughput by balancing I/O operations across the two host ports. Host port fault tolerance is also achieved, because the host can continue to access the controller if one host channel fails.
Active-Active Single Port This option allows both controllers to operate independently and as in an active-active pair. Active-Active modes allow two controllers to cooperate in system operation in a fault-tolerant manner. If one controller fails while in Active-Active mode, the other controller assumes its activities, allowing host access to continue.
When both controllers are online, each controller presents its LUNs on only one port.
Active-Passive Dual Port This option allows you to use just one controller with the second controller acting only as a backup in case of a failure of the controller in use.
When you change to this mode on one controller, you must reboot both controllers at the same time. After rebooting, both controllers will automatically be in Active-Passive Dual Port mode.

Clearing Metadata from a Drive
All of the member drives in an array contain metadata in the first sectors of the
drive. The controller uses the metadata to identify array members after restarting
or changing controllers.
You can clear the metadata from a drive if you have a drive that was previously a
member of an array. Drives in this state display Leftover in the Display Drives
screen. After you clear the metadata, you can use the drive in an array or as a spare.

Adding a Hot Spare
Dedicated spares are unused disk drives that you assign as a spare to a specific
array. The disk must be as large as the smallest member of the array. You cannot
use a dedicated spare drive in an array as a pool spare.
Although using a dedicated spare is the most secure way to provide spares for
your arrays, it is also expensive to keep an idle drive assigned to each array. An
alternative method is to assign one or more idle drives to the spare pool. See
“Adding A Pool Spare” on page 118.
You assign dedicated spare drives to a specific array. If a member drive in the
array fails, the controller uses a dedicated spare drive to automatically reconstruct
the array. You can add dedicated spare drives to mirrored (RAID 1 and RAID 10)
and parity (RAID 3, RAID 4, RAID 5, and RAID 50) arrays when you create the
array or afterward. You can assign up to four dedicated spare drives to an array.
CAUTION: A spare cannot be added that does not have enough capacity to
replace the smallest member in the array.
To add a dedicated spare:
1 Sign on to the Administor Server, refer to “Signing On to a Domain” on
page 52.
2 Click on the Session menu and choose Client View, then select Logical.

You can upgrade the firmware on the controller. Information regarding the latest
release of firmware and firmware updates is available on our support web site.
AdminiStor’s Flash Utility button is not the same as the Flash Utility provided
through VT-100 controller boot operation. AdminiStor’s Flash Utility button
allows the user to update the controller firmware and it prevents a situation with
dual controllers, where one controller has newly updated firmware and it is now
different from the other controller. Under this condition, the first controller to
boot senses the difference in firmware and kills the other controller. To prevent
this, AdminiStor employs a method that updates both controllers at one time.
Also, AdminiStor uses an in-band method to update the firmware by using the
SCSI bus rather than the RS-232 port.
You use the Flash Utility to download a new firmware file (.fla file) for your
controller.
If your controller is set to Active-Active/Active-Passive mode, you must stop all
I/O operations prior to updating the firmware.
To upgrade the controller’s firmware:
1 Sign on to the Administor Server, refer to “Signing On to a Domain” on

Active-Active Mode In Active-Active mode, two controllers cooperate to provide redundancy. If one controller fails, the remaining controller will take over the failed controller’s functionality.
Active-Passive Mode In Active-Passive mode, one controller enables both its host ports and presents all LUNs on both ports. The other controller keeps both its host ports passive, and does not service any LUNs. Both controllers monitor each other’s heart beats and the passive controller receives write data and parity logs from the active controller.
BBU See “Battery Backup Unit” on page 157.
Bad Block Table (or Bad Data Table)
There are two bad-block tables that the controller automatically maintains: The Rebuild Bad Block Table stores information on bad blocks encountered during a rebuild or consistency check process. The Write-Back Bad Block Table stores information on all irrecoverable write-back errors that occur. AdminiStor provides an Error Table in which you can see Bad Block Data and Request Sense Data.
Battery Backup Unit A Battery Backup Unit is an add-on module that provides power to an the imageRAID Controller cache memory in the event of a power failure. The battery backup module monitors the write back cache on the controller, and provides power to the cache if it contains data not yet written to the drives when power is lost.
Cache Controller memory used to speed up data transfer to and from a disk.
Cache Flush Refers to an operation where all unwritten blocks in a Write-Back Cache are written to the target disk. This operation is necessary before powering down the system.

Cache Line Size The Cache Line Size function, available in Controller Options or Manual Configuration, is set in conjunction with stripe size and represents the size of the data “chunk” that will be read or written at one time. The cache line size should be based on the stripe size you selected.
Channel Refers to one bus on the imageRAID Controller. Each controller provides at least one channel, and additional channels with optional upgrades.
Chunk Size The chunk size is the amount of contiguous data that is written to an array member before moving to the next member of the array. This is also know as stripe size.
Consistency Check Refers to a process where the integrity of redundant data is verified. For example, a consistency check of a mirrored drive will make sure that the data on both drives of the mirrored pair is exactly the same. For RAID Level 5 redundancy, a consistency “connect” is a function that allows a target device (typically a disk drive that received a request to perform a relatively long I/O operation) to release the bus so that the controller can send commands to other devices. When the operation is complete and the bus is needed by the disconnected target again, it is “reconnected.”
Critical: A Logical Drive is in a “critical” state if...
It has been configured at RAID level 1, 3, 5, or 0+1; andOne (and only one) of its member drives is not “online.”A logical drive is considered “critical” because any failure of another of its member drives may result in a loss of data.
NOTE: I/O operation can only be performed with logical drives that are online or critical.
Dead: A disk drive is in a “dead” state if it...
Is not present; or
If it is present but not powered on; or
If it failed to operate properly and was “killed” by the RAID Controller.
When the controller detects a failure on a disk, it “kills” that disk by changing its state to “dead.” A drive in a dead state does not participate in any I/O activity. No commands are issued to dead drives.
Disk Failure Detection The controller automatically detects disk failures. A monitoring process running on the controller checks, among other things, elapsed time on all commands issued to disks. A time-out causes the disk to be “reset” and the command to be retried. If the command times out again, the disk could be “killed” (taken “offline”) by the controller (its state changed to “dead”).

Disk Media Error Management
The RAID Controllers transparently manage disk media errors. Disks are programmed to report errors, even ECC-recoverable errors. When a disk reports a media error during a read, the controller reads the data from the mirror (RAID 1 or 0+1), or computes the data from the other blocks (RAID 3, RAID 5), and writes the data back to the disk that encountered the error. If the write fails (media error on write), the controller issues a “reassign” command to the disk, and then writes the data to a new location. Since the problem has been resolved, no error is reported to the system.When a disk reports a media error during a write, the controller issues a “reassign” command to the disk, and writes the data out to a new location on the disk.
Disk Array A disk array is a group of individual disk drives (preferably identical) that are logically tied to each other and are addressed as a single unit. In some cases this may be called a drive “pack” when referring to just the physical devices.All the physical devices in a drive array should have the same size, otherwise each of the disks in the group will effectively have the capacity of the smallest member. The total size of the drive array will be the size of the smallest disk in the group multiplied by the number of disks in the group. For example, if you have 4 disks of 400MB each, and 1 disk of 200MB in a pack, the effective capacity available for use is only 1000MB (4*200), not 1800MB
Dual-Active (Duplex) Mode
A method of interconnecting multiple RAID controllers that share a common set of drives. In addition to increasing overall performance, this method allows a surviving controller to take over resources of a failed controller. This “failover” process is transparent to the host.
Duplex Mode See “Dual-Active (Duplex) Mode” on page 159.
Error Table See ““Bad Block Table (or Bad Data Table)” on page 157”.
Failback In Active-Active mode, failback is the act of returning ownership of controller resources from a surviving controller to a previously failed (but now active) controller. The resources include disk arrays, cache data, and host ID information.
Failover In Active-Active mode, failover is the act of temporarily transferring ownership of controller resources from a failed controller to a surviving controller. The resources include disk arrays, cache data, and host ID information.

Hot Replacement of Disks (“Hot Swap”)
The design of the RAID Controllers allows for the replacement of failed hard disk drives without interruption of system service. In the event of a drive failure on a properly configured system (where the data redundancy features of the controller are used), system service continues without interruption. A message is generated by the system to alert the system operator.When a replacement drive becomes available, the system operator can remove the failed disk drive, install a new disk drive, and instruct the controller to “rebuild” the data on the new drive, all without interrupting system operations.Once the rebuild is complete, the controller will be brought back into a fault tolerant state.
Host To LUN Mapping The Host To LUN mapping feature is intended for use in configurations in which multiple host computers attach to one or more RAID Controllers. This is also referred to as a Storage Area Network (SAN) configuration. The host to LUN mapping feature restricts host access to configured system drives. Access to a configured system drive is granted only to a single host or group of hosts. (3000F Only.)
Intelligent Battery Backup Unit
The Intelligent Battery Backup Unit (IBBU) is an add-on module that provides power to the RAID Controller cache memory in the event of a power failure. The battery backup module monitors the write back cache on the controller, and provides power to the cache if it contains data not yet written to the drives when power is lost.
JBOD Sometimes referred to as “Just a Bunch of Drives.” Each drive is operated independently like a normal disk drive, or drives may be spanned and seen as a single drive. This level does not provide data redundancy.
NOTE: The host operating system drivers and software utilities remain unchanged regardless of the level of RAID chosen. The controller makes the physical configuration and RAID level implementation transparent to the host operating system.
Logical Drives A logical drive is equivalent to a “system” drive. Logical drives are presented to the operating system as available disk drives, each with a capacity specified by the RAID Controller.
Logical Drive States The state of a logical (system) drive can be either ONLINE, CRITICAL, or OFFLINE. Notice that the same term “online” is used for both physical and logical drives.
Logical Unit Number (LUN)
A representation of a system drive (logical drive) on a given channel and target ID.

LUN See “Logical Unit Number (LUN)” on page 160.
LUN Mapping (3000F Only)
LUN Mapping allows logical drives (or system drives) to be made available or unavailable on one or more host ports. The mapping is performed by assigning Logical Unit Numbers (LUNs) to logical drives. The LUN assignments are per host port and are independent of the assignments on other host ports.By not assigning a LUN to a logical drive on a particular host port, that logical drive is made inaccessible to that host port.
Management Information Base (MIB)
A MIB is a database of managed objects accessed by network management protocols. An SNMP MIB is a set of parameters that an SNMP management station can query or set in the SNMP agent of a network device.
Mirroring Refers to the 100% duplication of data on one disk drive to another disk drive. Each disk will be the mirror image of the other.
Online: A Logical Drive is in an “online” state if...
All of its member drives are “online” and available.
Offline: A Logical Drive is in an “offline” state if...
No data can be read from it or written to it.System commands issued to offline logical drives are returned with an error status: no operations can be performed on offline logical drives. A logical drive can be “offline” under one of two situations described below:
• It is configured with a redundant RAID level (1, 3, 5, or 0+1), and two or more of its member drives are not “online”; or
• It is configured at RAID level 0, JBOD, or in a spanned set (PCI only), and one or more of its member drives are not “online.”
Online: A disk drive is in an “online” state if it...
Is powered on; and
Has been defined as a member of a drive array; and
Is operating properly.
Other Controller In Active-Active mode, the opposite controller from the one currently being used (that is, not the local controller) is referred to as the other controller.
Ownership In an Active-Active configuration, a single controller has ownership of he following resources: arrays and dedicated spares. When a controller fails, the other controller assumes temporary ownership of its resources.
Pack See “Disk Array” on page 159.

Parity See “Rotated XOR Redundancy” on page 163.
Physical Drive States Refers to a drive’s current operational status. At any given time, a drive can be in one of five states: READY, ONLINE, STANDBY, DEAD, or REBUILD.The controller stores the state of the attached drives in its non-volatile memory. This information is retained even after power-off. Hence, if a disk drive is labeled DEAD in one session, it will stay in the DEAD state until a change is made either by using a system level utility or after a rebuild. Each of the states is described below:
Pool Spare Pool spares are one or more disk drives set aside for redundant arrays that will automatically be selected to replace a failed drive, should that occur. These are different from hot spare drives where hot spares are assigned to a specific redundant array.
RAID RAID stands for Redundant Array of Independent Disks. Several different forms of RAID implementation have been defined. Each form is usually referred to as a “RAID level.” The basic RAID levels supported by the RAID Controllers are shown below.
The appropriate RAID level for a system is selected by the system manager or integrator. This decision will be based on which of the following are to be emphasized:
• Disk Capacity
• Data Availability (redundancy or fault tolerance)
• Disk Performance
RAID Controller The controller acts as a bridge between host channels and drive channels, and implements the RAID function. On the drive channels, the controller acts as an initiator. The host channel ports are implemented as target IDs, with logical drives presented as LUNs under the target IDs.
RAID Operation imageRAID Controllers use their host ports to connect to one or more Host Bus Adapters in one or more host computer systems.Each configured logical drive consumes a particular bus-target ID-LUN on the host system. Multiple sets of disk drives are connected to the controller via its drive channels.
In duplex, or Active-Active mode, two identical imageRAID Controllers are connected to the same hosts via their host ports, to the same drives via their drive channels, and to each other via a special hardware link for heartbeat sensing. This forms a redundant controller system. The two controllers work together handling data traffic and mirror their write data in each other’s cache memory. If one of the controllers fails or otherwise becomes non-operational, the surviving controller takes over its responsibilities with no loss of data.

RAID Levels RAID Advisory Board-approved RAID levels (RAID 0, RAID 1, RAID 3, RAID 5) and several special RAID levels (RAID 0+1, RAID 00, RAID 10, RAID 30, RAID 50, and JBOD).
Level 0 Block “striping” across multiple drives is provided, yielding higher performance than is possible with individual drives. This level does not provide any redundancy.
Level 1 Drives are paired and mirrored. All data is 100% duplicated on a drive of equivalent size.
Level 3 Data is “striped” across several physical drives. Maintains parity information which can be used for data recovery.
Level 5 Data is “striped” across several physical drives. For data redundancy, drives are encoded with rotated XOR redundancy.
Level 0+1 Combines RAID 0 striping and RAID 1 mirroring. This level provides redundancy through mirroring.
Levels 00, 10, 30, and 50.
Multi-layer RAID levels which span RAID levels 0, 1, 3, and 5 by striping data across drive arrays (RAID Drives).
Rebuild: A disk drive is in a “rebuild” state...
While it is in the process of being rebuilt. During this process, data is regenerated and written to the disk drive. This state is sometimes referred to as “Write-Only”’ (WRO).
Rotated XOR Redundancy This term (also known as “parity” or “consistency data”) refers to a method of providing complete data redundancy while requiring only a fraction of the storage capacity of mirroring. In a system configured under RAID 3 or RAID 5 (which require at least three drives), all data and parity blocks are divided between the drives in such a way that if any single drive is removed (or fails), the data on it can be reconstructed using the data on the remaining drives. (XOR refers to the Boolean “Exclusive-OR” operator.) In any RAID 3 or RAID 5 array, the capacity allocated to redundancy is the equivalent of one drive.
SCSI Drive A disk drive equipped with a SCSI interface (sometimes referred to as a SCSI Disk). Each disk drive will be assigned a SCSI address (or SCSI ID), which is a number from 0 to 7 (0 to 15 under Wide or Ultra SCSI). The SCSI address uniquely identifies the drive on the SCSI bus or channel.
Simplex Mode See “Single Controller (Simplex) Mode” on page 163.
Single Controller (Simplex) Mode
A single controller attached to a set of drives that offers RAID functionality without the controller fault tolerance inherent in dual-active mode.

Simple Network Management Protocol (SNMP)
SNMP is the Internet standard protocol, defined in STD 15, RFC 1157, developed to manage nodes on an Internet Protocol (IP) network.
Standard Disk Drive This term refers to a hard disk drive with SCSI, IDE, or other interface, that is attached to the host system through a standard disk controller.
Standby Replacement of Disks (“Hot Spare”)
The “Standby Replacement” (or “Hot Spare”) is one of the most important features the controller provides to achieve automatic, non-stop service with a high degree of fault-tolerance. The rebuild operation will be carried out by the controller automatically when a disk drive fails and both of the following conditions are true:
• A “standby” disk drive of identical or larger size is found attached to the same controller;
• All of the system drives that are dependent on the failed disk are redundant system drives, e.g., RAID 1, RAID 3, RAID 5, RAID 0+1.
NOTE: The automatic rebuild will only happen on the SAME controller, never across controllers.
During the automatic rebuild process, system activity continues as normal. System performance may degrade slightly during the rebuild process.
To use the automatic rebuild feature, you should always maintain a hot spare drive in your system. When a drive fails, the hot spare will automatically replace the failed drive and the data will be rebuilt. The system administrator can disconnect and remove the bad drive and replace it with a new drive. The administrator can then make this new drive a hot spare.
Stripe Order The order in which disk drives appear within a drive array. This order must be maintained to access the data correctly, and is critical to the controller’s ability to ‘Rebuild’ failed drives.
Stripe Size The stripe size is defined as the size, in kilobytes (1024 bytes) of a single I/O operation. A stripe of data (data residing in actual physical disk sectors, which are logically ordered first to last) is divided over all drive array disks.
Stripe Width The number of striped drives within a drive array.
Striping Refers to the storing of a sequential block of incoming data across multiple drives in a group. For example, if there are 3 drives in a group, the data will be separated into blocks and block 1 of the data will be stored on drive 1, block 2 on drive 2, block 3 on drive 3, block 4 on drive 1, block 5 on drive 2 and so on. This storage method increases the disk system throughput by ensuring a balanced load among all drives.

System Drive Affinity See “LUN Mapping (3000F Only)” on page 161.
System Drives See ““Logical Drives” on page 160”.
Target A target is a device (peripheral) that responds to an operation requested by an initiator (host system). Although peripherals are generally targets, a peripheral may be required to at temporarily as an initiator for some commands (for example, SCSI EXTENDED COPY command).
Target ID A target ID is the ID of a device attached to a controller.
Topology A network topology refers to the physical layout of nodes on a network. Topologies range from local network topologies to WAN topologies. FC topologies include point-to-point, FC-AL, and fabric.
Trap In the context of SNMP, a trap is an unsolicited message sent by an agent to a management station. The purpose is to notify the management station of some unusual event.
Unconfigured: A disk drive is in a “unconfigured” state if it...
Is powered on; and
Is able to operate properly; and
Was NOT defined as part of any drive array.
Unkill In Active-Active mode, when a surviving controller removes the reset from the other controller, it unkills it. The other controller will reboot and attempt to come online.
Write Back Cache Refers to a caching strategy whereby write operations result in a completion signal being sent to the host operating system as soon as the cache (not the disk drive) receives the data to be written. The target drive will receive the data at a more appropriate time, in order to increase controller performance. An optional cache battery backup or an Uninterruptable Power Supply (UPS) can be used to protect against data loss as a result of a power failure or system crash during the time the data is only in the cache.
Write Through Cache Refers to a caching strategy whereby data is written to the drive before completion status is returned to the host OS. This caching strategy is considered more secure, since a power failure is less likely to cause loss of data. However, a write through cache results in a slightly lower performance.

Domains
As described in chapter 3 – Startup and Navigation, the Domains menu provides
administrator’s of AdminiStor Plus with the ability to customize the viewing and
managing of enterprise wide imageRAID SCSI Series Storage System. This is
accomplished through the creation of logical domains, which differs from the
physical domains.
The physical domain consist of a host system and it’s devices (i.e., host computer, controller, physical disks, enclosures, channels, logical drives (LUNs), etc.). It is the physical components that compose the host system.
The logical domain comprise a mixture of the physical attributes of the physical domains and can include components of other previously created logical domains. Once you have logged into the physical domains or logical domains, you can create a logical domain by choosing components of those physical domains which will be contained in the logical domain. Creating logical domains is useful when a user is responsible for devices on more than one physical domain. If you add all the devices in the physical domain they “own”, then they will only have to log on to one logical domain as opposed to the physical domain. This allows the user the ability to create customized domains by creating and performing a single login for a specific logical domain.
To maintain a proper topology, if a device is added to a logical domain but the “parent” of that device is not added, the parent will show in the Client View tree but no access is given to the Client View panel.
In this appendix we will describe using the Domains menu features to enable
you to create and manage customized logical domains.
