HMC• Updates and Upgrades

Partition Maintenance• i5/OS & LIC, AIX, Linux



Check HMC code level and eFixes installed

Starting with V4R5, this interface was enhanced to automatically show eFix information along with Version Release, even from a WebSM session

To view Version/Release, Expand License Internal Code Maintenance and select HMC Code Update. Prior to V4R5, the only way to see eFixes was to select ‘Help’ on the HMC Code Update panel on the HMC. eFix information was not available from a WebSM session

Notice that HMC code uses a Version/Release format and maintenance is identified by MHxxxxx ptf IDs. MHxxxxx PTF’s are also used for i5/OS server firmware maintenance.



Multiple ways to check HMC code level on V7.310Just hover the cursor over the HMC Version on the Welcome screen or select Updates.

Select the Updates tab



Upgrading and Updating the HMCTerms

– Upgrading the HMC– Changing the HMC to a new

Version or a new release level– Recovery Media = Upgrade

– Updating the HMC– Updating the HMC within the

current release– Install Corrective Service

– i.e. Applying a V5R2.0 required efix

– Bring the HMC to a new point release by installing an update PTF

Upgrading or Updating the HMC is a Concurrent Process (performed independent of the servers that it manages)

Obtain the HMC code maintenance – Traditional

– Order the fix as a PTF and is received on media

– Internet– Fix or Update file can be downloaded

directly to the HMC– Zip file can be downloaded

– Zip file can be used with the updhmc command or copied from a FTP server that’s behind the firewall

– ISO file can be downloaded and burned– Image of the media, requires an

authoring program

– FTP– Files can be downloaded to any FTP

server that HMC can access



Upgrading the HMC to a New ReleaseVer/Rel/point_level of HMC i.e. (V6.1.3 = version 6, release 1, point level 3)HMC version upgrade required Recovery media.

– Starting with version 5, release upgrades require recovery media– V4.x to V4.x (Could be done using Recovery media or Update media)– V4.5 to V5.1 – Recovery media required– V4.5 (with special steps) to V6.1 – Recovery media required– V5.2 to V6.1.x – Recovery media required– V6.1.2 to V7.310 – Recovery media required– V7.3.3 must use recovery media AND come from V7.3.1 or V7.3.2

Recovery Media is an Upgrade - (boot the HMC from media)– One step short of a scratch install– Upgrade option preserves saved upgrade data on hard drive and/or media– Overwrites all other HMC code and configuration files

Update the HMC release using Corrective Service– Uses an update PTF instead of Recovery Media – Overwrites existing files, adds those needed, does not change the recovery point– Can increase time need for Backup Critical Console Data

Starting with V5R1can upgrade

and install the HMCfrom a server on

the network

HMC V7 R3.3.0 (Released on 5/7/08) upgrade notes

Prerequisite task required to preserve existing HMC configuration

Save Upgrade Data

Upgrading from HMC V6.1.2 or higher HMC V6 is a two-step process. You must first upgrade via Recovery media to HMC V7 R3.1.0 or HMC V7 R3.2.0 before you can upgrade to HMC V7 R3.3.0

Required for upgrade from lower level of HMC V7.

Optional Network install or Upgradehttps://www14.software.ibm.com/webapp/set2/sas/f/hmc/power6/install/v7.Recover_Network.html#PXE

This is an example using Network images



Upgrade procedure using DVD media



Back Up Critical Console Data

• What gets Backed Up• Where can the Back Up be Saved• Performing a Back Up• Restoring Critical Data



What gets Backed Up

Those files with a timestamp later than the trigger file are candidates for backup.

The data that is backed up can be divided into 2 categories

– HMC specific– User Profiles– Roles and Tasks– Network Configuration– Applied Corrective Service Updates

– HMC operating system– Service packs, eFixes– OS Security update– Infocenter

In general, Backup Critical Console Data archives:

– Code Changes to the HMC Application(s) since the last install or recovery upgrade

– HMC unique configuration changes since the last install or recovery upgrade

– User Profiles– Network Configuration– Service Data– Etc.

– Platform specific information since the last install

– Managed Systems– Partition Profiles – Etc.

– HMC operating system updates applied since the last install



Save Critical Console Data (Save CCD) vs. Save Upgrade data

CCD is not a ‘bootable’ save of the HMC– In a recovery scenario you need:

– The HMC Recovery CDs (or DVDs) that were used with the install or the last upgrade – PLUS the Save CCD data.

– Options to Save to: – DVD-RAM– FTP server– NFS server

Save Upgrade data is different from CCD– Use this option only before HMC Upgrade– Saves only user modified System configuration, User Profile & Security info,

Service information



HMC Backup options

Saving Critical Console data should be part of your normal system management process. A backup should be performed following any significant change. i.e. upgrades, updates, security changes – other user customizations, etc. It will save all changes to the HMC firmware and all users modifications.

To back up the HMC (Back-up Critical Console Data), you must be a member of one of the following roles:

• super administrator • operator • service representative To back up the HMC, do the following: 1. In the Navigation area, click the Licensed Internal Code

Maintenance icon. 2. In the Contents area, click the HMC Code Update icon. 3. Select Back up Critical Console Data. 4. Select an archive option. You can back up to DVD on the

HMC, back up to a remote system mounted to the HMC file system (such as NFS), or a remote site through FTP.

5. Follow the instructions on the panel to back up the data.

Recovery mediaRequired for version upgrades / Suggested for release upgrades.

Benefit to install from Recovery CD'sBecomes the new the recovery point Reset the Save CCD data pointReduces the volume of data to be save by Save CCD

Upgrade release level using update.zip files. Increased the volume of data to be saved by 'Save Critical Consol Data‘ (save CCD).

Makes a copy of every object that has changed since the base install or last recovery media Example: system ships with V4R1.0 preloaded.

Update using Update.Zip files to move to V4R2.0 then V4R3.0 then V4R4.0Recovery point is still V4R1 Recovery CD’s plus the Critical Console Data after V4R4.0

Recommended: Upgrade procedure with Recovery media:Example: Upgrade from V4R1 to V4R4 the procedure would be:

1) optional – Save CCD2) Save Upgrade Data3) Boot from the V4R4 Recovery CD's MH002214) Restore the saved Upgrade Data (will occur automatically as part of the upgrade)5) Apply any V4 R4.0 Required Maintenance efix (MH00219 in this example)6) Save Critical Console Data7) Recovery point is now V4R4 CD’s, plus CCD taken after maintenance



Why CCD backup can take a while…Two methods of HMC software Release Upgrades

– Update via corrective service –‘Update.zip’ files

– Upgrade with new release Recovery CD’s (V5R1 and later uses DVD media) For example upgrading from V5R1 to V5R2 or directly to V5R2.1

Size matters – could be +1GBSave performance is improved

HMC Network Connection options



POWER5 570 with “optional” redundant FSP and single HMCNOTE: POWER6 570 – 5-way or larger, automatically has redundant FSP

The option for dual service processors on the POWER5 570 was introduced in October, 2005. Dual service processor support is available only on the 5/8 way or larger 570 systems and requires anHMC to manage this. The HMC and server firmware must be on minimum HMC code level and server firmware level, and HMC must be correctly networked to support dynamic FSP failover.

The HMC must attach to both FSPs on the 570 using an Ethernet switch or hub. Typically this would be HMC0 ports. The HMC can provide DHCP services for IP address assignment or static IP addressing may be used

Attach a standard Ethernet cable (or cross-over cable) from HMC1 port on the first service processor directly to HMC1 port on the second service processor. This is required for failure detection and dynamic failover.

POWER6 570 two enclosure (5/8 way or larger) comes standard with dual FSPs and the HMC1 to HMC1 connecting cable is no longer needed.

HMC provides multiple User Interfaces and AccessLocal GUI (on HMC)– Starts automatically whenever the HMC is started– Requires user login prior to access– HMC V7.310 introduced Browser based user interface

– (eliminates need for WebSM for remote access & management)

Remote GUI (on network PC)– Uses an installable standalone remote client application (WebSM Client)

– Windows (NT,XP) or Linux– Downloadable as an installable application directly from the HMC, via web browser

– Also supported from one HMC to another, also to/from AIX 5L– Can be SSL secured through public/private key files

– Generate on the HMC, and transfer to client systems

Local Command Line (on HMC)– Launched from the HMC desktop– Linux based commands - Restricted to a set of supported HMC commands

Remote Command Line (on network PC)– Accessed through encryption-protected Secure Shell (SSH)– Key files can be set up and exchanged to avoid password prompts

– Very useful for automation and scripting without human intervention



HMC V6 and earlier - Remote GUI management requires WebSM:(Web-based System Manager)

Two WebSM clients available:– Web-based System Manager Remote Client– Web-based System Manager Remote Client for Java Web Start – Either client works the same after installation

Remotely access your HMC by installing WebSM client on your PC workstation

WebSM client allows you to manage your system from virtually anywhere – Up to 5 remote clients can be logged in simultaneously

The HMC and WebSM can negotiate SSL encryption for additional security

Some tasks not available using the remote client– These tasks include restarting the HMC interface and configuring System Manager Security for

certificate authority or viewing overview and status information. – Some of these functions are available remotely using SSH command line interface

– V7.310 remote management resolved some of these limitations, such as rebooting the HMC

HMC V7 and after - Remote GUI access via Secure Browser - WebSM is no longer needed or supported.

– The uncapped partitions will share all the available cycles: – They consume an entire processor if available

(when dedicated at 0%) and – Split a processor when the dedicated processor is

fully utilized.

– The total processor capacity in the system is better utilized.

– Dedicated proc LPs still maintain their perf characteristics and predictability



HMC R7V3.1.0 – HMC Management EnhancementsNew monhmc command

– Can gather disk space usage and system memory usage

– Some specific processes on the HMC are monitored

Clickable SRCs– The new browser-based interface allows a user

to click on an SRC or Progress Code and pop-up a description of the SRC.

– Concurrent GX+ adapter add & cold repair for L4 / ML– Redundant Service Processor for ML – Enabled at EM320 – Energy Scale (Active Energy) Support – Scheduled Operations for Utility Capacity on Demand

Virtualization Management– Partition Mobility (between servers managed by same HMC)– Multiple Shared Processor Pool Support

HMC Management – User Authentication via Kerberos – Enhanced HMC Monitoring – Ongoing HMC Performance Improvements

Power HMC – V7R3.2.0 Content Overview



HMC V7R3.2.0 – Hardware Discovery OverviewThis function requires 320 level system firmware (or newer).

Functional improvements: – Provides capability to collect I/O device information before partitions and OS’s

are configured or booted to make configuration easier. – Provides HMC users more detailed view of slot contents especially child

devices.– Can view storage device information (what’s on the SCSI bus). – Can view Ethernet MAC addresses and FibreChannel WWN’s via HMC. – Can even be done before partitions are configured.

– Provides more detailed inventory to System Plan Tool to verify system configuration and validate customer orders.

Hardware Discovery can be performed three ways1. Initial Power On (after system leaves IBM): Hardware Discovery performed

automatically. • Only when system is in non-partitioned mode and IO data hasn’t already been collected.

2. New Power On “Hardware Discovery” option.• I/O data collected for both assign and unassigned I/O.

• Existing LPs booted into Hardware Discovery; later returned to (bootable) state.• Special LP used to collect I/O data for unassigned I/O.

• System left in Operating state (no auto-boot of partitions).3. Is initiated automatically by System Plans tool. (see next function)



User initiated Hardware Discovery from the HMC.

System Powers On and collects IOR data utilizing service partition.

System left in “Operating” state upon completion.

Partition auto-boot settings not enforced on this type of power on (are persisted for future).

When to use this option:

After repair and verify.

After attaching new expansion unit.

After firmware upgrade.

Create System from HMC – (export / import SPT)

The System Planning Tool (SPT) is free, it runs on a stand-alone workstation and enables the user to design a new system. Select the Machine Type and Model, processors, memory and IO hardware, and design the partitions. This can be sent to IBM order processing and manufacturing can build to the plan specifications. The SPT output can also be imported by the HMC and the DEPLOY option can automatically create the partitions.http://www-304.ibm.com/systems/support/tools/systemplanningtool/

HMC / ASM provides a small subset of the EnergyScale features.– Enable / Disable of Power Saver Mode– Schedule Operation for Power Saver Mode– Pass through channel for PowerExecutive / Director

PowerExecutive / Director provides the complete set of EnergyScale functions.

– PowerExecutive was originally a power management plugin for System x. It is now the official management console for EngeryScale feature



HMC V7R3.2.0 – Energy Scale CapabilitiesHMC displays 2 capabilities for power saver mode:

– Firmware power saver capable –Whether the firmware running on the server is capable for power saver mode

– Hardware power saver capable –Whether the hardware supports the power saver mode.

HMC User Interfaces: – GUI (Managed system properties

panel) and – Command line (lssyscfg -r sys)



HMC V7R3.2.0 – Energy Scale, Power Saver ModeWith power saver capable systems, users can enter static power save through the power saver mode configuration task.

With power saver mode enable, the processing utilization reporting might not be accurate if the OS does not have the proper support.

Commands for power saver mode: chpwrmgmt and lspwrmgmt

Scheduled Operation for Power Saver Mode



Terminology

Additional capacity assigned to a virtual pool for the purpose of reserving uncapped cycles for the VSPP’s use. Must be less than Maximum Pool Capacity. Cannot be stolen by the HMC during partition activation. The units are processor units and for HMC users the granularity is 0.01 processor units.

Reserved Pool Capacity

A computed quantity – not user specified.This is the number of CPU cycles guaranteed to be available to the set of partitions in the virtual pool. It is equal to the sum of the entitled capacities of the partitions in the VSPP (pending processor units of the active and inactive partitions) plus the Reserved Pool Capacity for the VSPP. Must always be Equal to or smaller than Maximum Pool Capacity. The units and granularity are the same as Reserved Pool Capacity.

Entitled Pool Capacity

Maximum Pool Capacity Maximum CPU cycles that can be consumed by the partitions in a VSPP (whole number of proc units).

– Not assigned to an active dedicated processor partition– Assigned to active dedicated processor partition that is capable of donation– Assigned to inactive dedicated processor LPs and system administrator has chosen to

make CPUs available for shared processor work when the LP is powered offVSPP Capacity



Prior to this Multiple VSPP support, all shared processor partitions were in the one and only Virtual Shared Processor Pool, pool 0, also known as the default pool

VSPP attributes:Pool ID – ranging from 0 to 63User Defined Name

“DefaultPool” for pool 0; can’t be changedReserve Pool Capacity

Exception: no Reserve Capacity for pool 0. Can’t be modified, not displayedMaximum Pool Capacity

Exception: pool 0 varies to cover remainder of PSPP. Can’t be modified, not displayedMaximum value (for non-default VSPPs) is maximum system processor capacity

VSPP Pool FunctionVSPPs are configured and unconfigured, not created or deleted, by setting Maximum Pool CapacityAll partitions must be moved out of a VSPP to unconfigure it, i.e. set the Maximum Capacity to zeroVSPP modifications can be done when the system is in the Operating or Standby states, and take effect right awayInitialize Profile Data will initialize all VSPPs, i.e. setting Maximum Pool Capacity and Reserved Pool Capacity to zero and pool names to the default names, after all the partitions are deletedDLPAR Add and Move of shared processing units will fail if target VSPPs Maximum Capacity is exceeded

HMC V7R3.2.0 – Kerberos Authentication, Overview

3. HMC sends principal name / TGT Request to KDC.

5. TGT returned to HMC

Kerberos KDC

(Key Distribution Center) Server

System i/p Server(s)

HMC6. Client (HMC) verifies

TGT with supplied PW.

2. User logs in to HMC (either local or remote)

Supplies User ID & PW

1. Remote User establishes https

session to HMC.

4. KDC computes encrypted TGT

using password.

. . .

7. If PW passes, all HMC operations proceed as normal. No further usage of Kerberos / TGT.

Remote Workstation (Web browser)

Kerberos TGT (Ticket Granting Ticket)



HMC supports MIT Kerberos V5.

Must have hmcsuperadmin authority to configure Kerberos Client IP on HMC.

Must configure (Extended Network Time Protocol) XNTP correctly and make sure both i/p HMC's date/clocks are in sync with all Kerberos KDCs.

HMC V7R3.2.0 – Kerberos Authentication, Configuration

Support both manual login as well as SSH (CLI)

SSH include Kerberos password-less login– Requires HMC Kerberos service key to be set-up– Requires client machine to support ssh GSSAPI (Generic Security Services Application

Programming Interface). This is usually found in the *nix ssh configuration file (hint: look for “GSSAPI” and enable).

– Requires client machine to be configured for Kerberos (i.e., client).– Requires client to obtain “forwardable” credentials prior is issuing ssh command (e.g., kinit

–f foobar@REALM).– Ssh supported GSSAPI options:

ssh -o PreferredAuthentications=gssapi-with-mic foobar@<hmc hostname>ssh -o PreferredAuthentications=gssapi foobar@<hmc hostname>



Option for access authentication:Local, Kerberos, LDAP
