2 OVERVIEW

WHAT IS THE RLM? Answer: The RLM (Remote LAN Module) is a management card available in FAS6000/V6000, FAS3000/V3000, and FAS3100/V3100 series controllers to provide remote platform management capabilities.

The RLM stays operational regardless of the operating state of the controller. The RLM is powered by standby voltage, which is available as long as the controller has input power to at least one of the controller's power supplies.

WHAT ARE THE FEATURES? Answer: The RLM provides secure out-of-band access to the controller, which can be used regardless of the state of the controller. The RLM offers a number of remote management capabilities for NetApp® controllers, including remote access, monitoring, troubleshooting, logging, and alerting features.

Some of the features of the RLM are:

• Remote access to controller console without using a serial terminal or a terminal concentrator • Remote access to controller power when you need to power off, power on, or power cycle the controller

remotely, without needing a LAN-based power strip to do so • Remote initiation of a core dump without requiring use of the NMI button on the controller • Remote access to hardware system event logs even when the controller is down

The RLM also extends AutoSupport capabilities of the NetApp controller by sending alerts or "down-filer" notification via an AutoSupport message when the controller goes down, regardless of whether the controller can send AutoSupport messages. These AutoSupport messages also provide proactive alerts to NetApp to help provide faster service.

IS IT SECURE? Answer: Absolutely. The RLM was designed with security as a core requirement.

The RLM implements a dedicated 10/100Mbps Ethernet interface. You must use a secure shell (ssh) client to log in to the RLM. It does not provide plain text-based protocols such as telnet or rsh. You can continue to use the same user credentials as defined in Data ONTAP to log into the RLM.

Page 4

HOW DO YOU ACCESS THE SYSTEM CONSOLE OVER LAN? Answer: Once the RLM is configured, you can connect to the RLM using a secure shell client, such as SSH and OpenSSH on UNIX® hosts or PuTTy on Windows® hosts. You can issue the system console command at the RLM prompt to access the system console.

RLM toaster> system console Type Ctrl-D to exit. (Press the Enter key to see the storage system prompt.)

toaster> toaster> vol status (Information about all of the existing volumes is displayed.)

toaster> (Type "Ctrl-D")

RLM toaster> DOES RLM HAVE A BATTERY?

Answer: No, the RLM does not have a battery. The RLM is powered by the controller's standby voltage, which is available as long as the controller has AC input power to at least one of the controller's power supplies. The RLM continues to operate even if the controller DC power is turned off. For example, issuing the following command from the RLM turns off DC power to the controller, but the RLM will continue to operate:

RLM> system power off

DOES THE RLM CAPTURE LOSS OF AC POWER INPUT?

Answer: Yes. The controller's power supplies were designed to supply power for a few milliseconds after complete power-off (such as removing plugs from the power outlets). In those few milliseconds, the RLM will record the "loss of power" event.

WHICH SYSTEMS ARE SUPPORTED? Answer: RLM is supported on all variants of FAS3000, V3000, FAS3100, V3100, FAS6000, and V6000 platforms. RLM is included by default as part of the base configuration of the supported platforms with the exception of the following platforms:

RLM is available only as an optional add-on card on FAS3020, V3020, FAS3050, and V3050 platforms. However, the cards are shipped as part of the base configuration in these platforms if the customer purchased a SupportEdge Premium service package.

HOW CAN I DETERMINE IF RLM IS INSTALLED?

Answer: Check "sysconfig -a" output for RLM information. A typical "sysconfig -a" output looks like the following:

Remote LAN Module Status Online

Gateway: 10.10.123.1

You can also physically check the presence of the RLM by inserting a network cable into the RLM port on the controller and checking the link light for the link status.

3 RLM SETUP

HOW DO I SET UP THE RLM? (internal) Answer: RLM can be configured in either of the following ways.

1. You can configure the RLM card using the boot menu when you initially set up your controller. NetApp recommends that the RLM be configured at this stage.

2. You can also configure the RLM by running the "setup" command after the system has booted. The RLM setup script is automatically invoked at the end of controller setup.

3. You can also set up the RLM after the controller has been set up by running the Data ONTAP "rlm setup" command.

HOW DO I SET UP FROM THE BOOT MENU OR USING THE “SETUP” COMMAND? Answer: The following two examples show how to set up the RLM during initial setup of the controller. The first example shows an RLM configuration with DHCP and the second example shows an RLM configuration with a static IP address.

DHCP toaster> setup <... At the end of system setup, RLM setup questions are automatically asked if an RLM is detected in the controller. ...> The Remote LAN Module (RLM) provides remote management capabilities including console redirection, logging and power control. It also extends AutoSupport by sending additional system alerts. Your AutoSupport settings are used for sending these alerts via email over the RLM LAN interface.

Please enter the name or IP address of the mail host []: mailhost.xyz.com Please enter the IP address for mailhost.xyz.com []:10.57.160.114

HOW DO I CONFIGURE WITH DATA ONTAP? Answer: The RLM card needs to be configured with a network address (IP address, netmask, gateway) for its dedicated 10/100Mbps Ethernet port. The RLM also uses Data ONTAP settings for AutoSupport, including the mail host address and the list of e-mail recipients.

You can configure the RLM card as part of the "setup" command as shown above.

You can also set up the RLM after the controller has been set up by running Data ONTAP's "rlm setup" command.

Here's an example of using the "rlm setup" command with a static IP address:

toaster> rlm setup The Remote LAN Module (RLM) provides remote management capabilities including console redirection, logging and power control. It also extends autosupport by sending additional system alerts. Your autosupport settings are used for sending these alerts via email over the RLM LAN interface. Would you like to configure the RLM? y Would you like to enable DHCP on the RLM LAN interface? n Please enter the IP address for the RLM []: 10.10.123.45 Please enter the netmask for the RLM []: 255.255.224.0 Please enter the IP address for the RLM gateway []: 10.10.123.1

WHAT IS THE NETAPP BEST PRACTICE FOR SETUP? Answer: RLM can be set up as part of the initial controller setup or later as a standalone component of the system. In either case, the following sequence will help you correctly set up the RLM:

1. Configure the RLM with correct network information by running the "setup" or "rlm setup" command from Data ONTAP.

2. Verify the RLM configuration using the "rlm status" command. If the "rlm status" does not show RLM to be "online," check that the network cable is correctly plugged into RLM’s Ethernet port and that the link is active.

3. Verify that AutoSupport options in Data ONTAP are correctly set up. 4. Use RLM to send a test AutoSupport message by running "rlm test autosupport" from Data ONTAP.

WHAT NETWORK INFORMATION WILL I NEED FOR SETUP? Answer:

- DHCP If you will be using DHCP addressing for the RLM, configure your DHCP server to assign a static IP address to RLM's MAC address. You can find RLM's MAC address by issuing the Data ONTAP command "rlm status" or by reading it off the MAC address label on the RLM module itself.

- Static IP

Page 7

If you are not using DHCP, you will need to collect the following network information before configuring the RLM:

- Static IP address to assign to the RLM - Network mask for the IP address - Gateway IP address

WHAT AUTOSUPPORT INFORMATION DO I NEED FOR SETUP? Answer: When setting up your controller from the boot menu or running the "setup" command, you will need to supply information for the mail host that can be used by the AutoSupport feature of the RLM. The mail host is a SMTP server that can be used by the RLM to send "down-filer" e-mail alerts. You will need: - Network name for the mail host or - IP address for the mail host

Note: The RLM uses "SMTP" to send AutoSupport messages. Even if your system AutoSupport is configured to use "http" or "https" transport, the RLM will use SMTP. You will need to configure the AutoSupport mail host and recipients for this to work. If the network name is specified for the mail host, DNS needs to be enabled so that Data ONTAP can resolve the hostname before sending to the RLM.

DOES THE RLM MAINTAIN ITS CONFIGURATION AFTER REBOOTS AND POWER CYCLES? Answer: Yes. The RLM keeps its configuration info at all times. Once configured, the RLM won't ever need to be configured again unless the user desires to change the configuration.

HOW DO I UNCONFIGURE THE RLM? Answer: In the extreme case that you want to leave the network cable disconnected and not use the RLM features, the following sequence of commands can "unconfigure" the RLM so that Data ONTAP stops monitoring for this error condition.

toaster> priv set advanced toaster*> options rlm.setup off toaster*> registry delete state.rlm.lan.dhcp toaster*> registry delete state.rlm.lan.ip toaster*> registry delete state.rlm.lan.netmask toaster*> registry delete state.rlm.lan.gateway Note that RLM features will not work after the above sequence of commands.

4 CONNECTION TO THE RLM HOW DO I CONNECT TO THE RLM?

Answer: You must use a secure client to connect to the RLM. ssh is a good UNIX/Linux client. Putty is a good Windows client.

unix-host% ssh naroot@<RLM_IP_address_or_hostname> You must supply a user name. The user name is the same user name that you use to log into your controller (Data ONTAP, Data ONTAP GX). The account must have administrative privileges on the controller. naroot is the default user name; by default the password for naroot is empty.

WHAT USER NAME DO I USE?

Answer: "naroot" is the default user name to connect to the RLM, with an empty password. If the user "root" on the controller is configured to have a password, the same password should be entered for user "naroot" on the RLM.

Page 8

Other users created by the "useradmin" command who have administrative privileges in Data ONTAP also can connect to RLM. You can create other user accounts on the RLM, but you cannot do it from the RLM's CLI. New user accounts can be created in Data ONTAP via the "useradmin user create" command. The users with the role "admin" are also given access to RLM. Passwords modified via the "password" command in Data ONTAP are updated on the RLM. Other password modification methods do not update the password on the RLM. Any modifications to a user profile are propagated instantaneously on the RLM.

Caution: NetApp strongly recommends that you create a password for the system administration account (root) for NetApp systems with an RLM installed. This provides additional security against unauthorized access to the system.

CAN I TELNET OR RSH INTO THE RLM?

Answer: No. Telnet/rsh is not secure. The only way to connect to the RLM is via ssh.

5 INSTALLING FIRMWARE

WHERE CAN I ACCESS FIRMWARE UPDATES? Answer: RLM firmware will be available at the NOW™ (NetApp on the Web) site.

HOW CAN I UPDATE FIRMWARE FROM DATA ONTAP? Answer: Updating RLM firmware from Data ONTAP is done in two easy steps.

1. Download RLM firmware to Data ONTAP using the "software" command. 2. Install the new firmware on the RLM using the "rlm update" command.

toaster> software install http://mywebserver.com/path/RLM_FW.zip -f software: copying to /etc/software/RLM_FW.zip software: 100% file read from location. software: /etc/software/RLM_FW.zip has been copied. software: installing software, this could take a few minutes... toaster> toaster> rlm update After new firmware is installed on the RLM, the controller will prompt you to reboot the RLM for new firmware to take effect.

Note: You must reboot the RLM for new firmware to take effect. Otherwise, the RLM will continue to be operational with older firmware.

HOW CAN I UPDATE FROM THE RLM CLI? Answer: You can use the "rlm update" command from the RLM CLI to update the firmware on the RLM.

8 AUTOSUPPORT INTEGRATION

HOW DO RLM AND AUTOSUPPORT WORK TOGETHER? Answer: The RLM automatically uses the AutoSupport configuration options from Data ONTAP. You can set up or modify "autosupport.to" and "autosupport.mailhost" options in Data ONTAP to configure AutoSupport. These changes will automatically be sent to RLM. If AutoSupport is enabled in Data ONTAP, RLM will send mail to recipients in the "autosupport.to" list. It will use the SMTP mail server specified in "autosupport.mailhost."

When the RLM detects that the system has failed, it will automatically send a "down-filer" AutoSupport e-mail to all addresses configured in Data ONTAP's "autosupport.to" option.

You use the "autosupport.content" option in Data ONTAP to change the amount of information contained in AutoSupport messages from Data ONTAP and RLM. The content can be set either to complete (contains complete configuration details) or minimal (strips private configuration data).

DOES RLM REPLACE AUTOSUPPORT? Answer: No, RLM augments Data ONTAP's AutoSupport features. When RLM detects that the system has failed, it will send an AutoSupport message signaling that an appliance is down—a "down-filer" notification. RLM does not send AutoSupport messages when the appliance is running normally. When Data ONTAP is up and running, it is responsible for its AutoSupport messages.

HOW CAN I TEST THAT AN APPLIANCE IS DOWN? Answer: To verify that the RLM AutoSupport function is working properly, ensure that AutoSupport options are configured in Data ONTAP.

options.autosupport.enable

options.autosupport.to

options.autosupport.mailhost

options.autosupport.content

Page 12

RLM will send an e-mail to recipients specified in autosupport.to.

You can enter the following command to trigger AutoSupport from RLM.

toaster> rlm test autosupport Verify that the e-mail is received from RLM. If options.autosupport.support is enabled, RLM will also send an e-mail to the support recipients specified in options.autosupport.support.to.

9 HARDWARE-ASSISTED TAKEOVER

WHAT IS HARDWARE-ASSISTED TAKEOVER? Answer: Hardware-assisted takeover enables systems with remote management cards to improve the speed with which takeover events are detected, thereby speeding up the takeover time.

When enabled, hardware-assisted takeover takes advantage of remote management card capabilities to detect failures on the local machine that could require a takeover. If a failure is detected, the card sends an alert to the partner node and, depending on the type of failure, the partner performs the takeover. This feature is available in Data ONTAP 7.3 or later on FAS3000, FAS6000, and FAS3100 series systems.

HOW DO I CONFIGURE ASSISTED TAKEOVER? Answer: This feature is enabled by default on systems that use an RLM.

1. Enabling this feature

This feature can be disabled/enabled by the following commands from the Data ONTAP CLI:

options cf.hw_assist.enable

options cf.hw_assist.disable

2. Setting partner IP address

By default, the IP address is the address of port e0a on the partner. It can be changed with this command:

option cf.hw_assist.partner.address address_or_hostname

3. Setting partner port number

The default partner port that will receive the alert is 4004. It can be changed by the following command from the Data ONTAP CLI:

option cf.hw_assist.partner.port port_number

HOW DO I TROUBLESHOOT?

When updating RLM firmware from RLM CLI, I get "FW package download from http://mywebserver.com/RLM_FW.tar.gz failed.....FAILED" This can be caused by the RLM being unable to resolve the Web server name specified in the "rlm update" command. Change the Web server name to an IP address for the Web server and retry the "rlm update" command.

Page 13

RLM toaster> rlm update http://IP-address-for-mywebserver.com/path/RLM_FW.tar.gz

I see this EMS message [rlm.driver.network.failure:warning]: " The network configuration of the Remote LAN Module (RLM) failed due to cable or network errors" This message is generated when:

• There is no network cable connected to the RLM's network interface, or, • The RLM is plugged into an inactive network, or, • The RLM is unable to autonegotiate a link on the network.

Please ensure that the RLM is connected to a 10/100Mbps-capable network and verify that the link status LED on the RLM's RJ45 connector is on.

I see this EMS message [rlm.driver.mailhost:warning]: "RLM setup unable to access mailhost specified in options autosupport.mailhost" This message is generated by the RLM management driver in Data ONTAP when it verifies the mail host specified in autosupport.options.

This message is generated if Data ONTAP is unable to resolve the mail host name to a valid IP address or if it is unable to open a session to the default SMTP port on this mail host.

This error can be corrected by one of the following methods:

1. Verify the current value of autosupport.mailhost using command "options autosupport.mailhost." If it is not correct please set it to the correct value using command "options autosupport.mailhost <mailhost-name or IP address>."

2. If the mail host name in autosupport.mailhost is correct, there may be an incorrect entry corresponding to this mail host in the /etc/hosts file. Verify and correct the associated IP address for this mail host stored in the /etc/hosts file. You can do this by mounting the root volume of your appliance on an administrative host and editing the /etc/hosts file under the root volume.

OR, rerun the command "setup" and specify the correct network name and IP address for the mail host to be used by RLM.

I have configured the RLM but still do not get a test e-mail from the RLM. There could be a number of causes for this, from incorrect configuration to network errors. But before we proceed on that path, please verify that you are issuing the following command to generate test e-mail from the RLM. Otherwise, the RLM will not send any e-mails unless there is a down-filer event.

toaster> rlm test autosupport If you have issued the above command and do not get a test e-mail from the RLM, take the following steps to isolate and fix the problem:

1. Check AutoSupport options to ensure AutoSupport is enabled, mail host is correct, and your e-mail address is configured correctly in the AutoSupport .to list.

2. Use Data ONTAP's "rlm status" command to get the IP address of the RLM. Ensure that you can ping RLM's IP address. Using a SSH client utility, verify that you can log into the RLM.

3. If you cannot ping the RLM, verify that a cable is plugged into the RLM's network port and that the link LED on the port is on.

4. If you are still unable to ping the RLM and you are using the DHCP address for the RLM, rerun the "rlm setup" command and try switching to the static IP address.

5. Ensure that your mail host is a valid SMTP mail server and does not require client authentication for sending outbound e-mails.

Page 14

Once the problem is fixed, you can generate a test AutoSupport e-mail from the RLM by issuing the following Data ONTAP command:

toaster> rlm test autosupport The RLM is autoconfigured for 10/100Mbit/s. Why does the network connection still appear to be so slow? The device connected to the RLM should be capable of autonegotiation, and should have autonegotiation enabled by default. Both devices will autonegotiate and choose the best possible mode of operation (e.g., the higher speed of 100Mbit/s is preferred over the lower speed of 10Mbit/s, and full duplex is preferred over a half duplex). If the device is not capable of autonegotiation, the RLM will assume half duplex because it is unable to determine the presence of full duplex. If the other device is capable of full duplex, a duplex mismatch would occur, the effect of which would be a working connection with very low speed.

Firmware Download and Instructions RLM firmware and installation instructions are available on the Download Software page on the NOW site. Here is the direct link.

Page 15

Why do we need to update RLM firmware in the field? The RLM is designed to be field upgradable. The upgrade is nondisruptive to the controller. This allows us to enhance the features provided by the RLM and also add new features to the RLM and to patch releases.

The idea is that you can update the firmware and get access to these improvements without having to replace your existing RLM or send it back to NetApp for upgrades.

What are the requirements for RLM's network interface? (internal) The RLM's network interface must be connected to an autonegotiating 10/100Mbps-capable device (e.g., Ethernet switch).

If you are setting up the RLM on a gigabit network, the network needs to be capable of autonegotiating to 10/100 speeds.

You do not need to tell the RLM if the network is 10 or 100. The RLM requires autonegotiation, so it can determine the network speed automatically.

The device connected to the RLM should be capable of autonegotiation, and should have autonegotiation enabled by default. Both devices will autonegotiate and choose the best possible mode of operation (e.g., the higher speed of 100Mbit/s is preferred over the lower speed of 10Mbit/s, and full duplex is preferred over half duplex). If the device is not capable of autonegotiation, RLM will assume half duplex, because it is unable to determine the presence of full duplex. If the other device is capable of full duplex, a duplex mismatch would occur, the effect of which would be a working connection with very low speed.

How can I use the RLM to control power to the controller (power on/off/cycle)? You can use the RLM "system power" command to control power to the system. For example, to turn the power off on the controller, you would use the command:

RLM toaster> system power off NOTE: Only users with administrative privileges will be able to run this command, because only users with "admin" privileges can log into the RLM and execute commands on the RLM CLI.
