Troubleshooting RLM problems

Verify the RLM is online and the IP configuration is correct by entering the following command:

toaster*> rlm status

If the RLM is configured using DHCP, reconfigure the RLM using a static IP address by entering the following command:

toaster*> rlm setup

Verify you are using a secure shell client to connect to the RLM. For information on secure shell client applications, see Prerequisite for logging in to the RLM.

From the storage system, verify the RLM is online and the IP configuration is correct by entering the following command:

toaster> rlm status

From the administration host, test the network connection for the RLM by entering the following command:

ra_host> ping rlm_IP_address

If the ping fails:

• Verify the RLM network port on the back of the storage system is cabled and active. For more information, see the Installation and Setup Instructions for your storage system.
• Verify the RLM has a valid IP address. (At the storage system, enter the rlm setup command to use the DHCP server or assign a valid IP address.).
• Verify the administration host has a route to the RLM.

From the storage system, reboot the RLM by entering the following command:

toaster> rlm reboot

Note
It takes approximately one minute for the RLM to reboot.

If the RLM does not reboot, repeat Steps 2 through 4. If the RLM still does not reboot, contact technical support for assistance.

Select test or feature by number [0]: 

From the RLM diagnostic prompt, enter test number 1 as shown:

Select test or feature by number [0]: 1

Note
It takes approximately ten minutes to complete this test.

Result

This initiates a comprehensive test that includes running tests 2 through 8, and 11. The results of each test are displayed.

Based on the results of Step 3, diagnose the problem. If the problem persists, reseat the RLM and repeat Steps 1 to 4.

If the problem still persists, replace the RLM.

Verify the RLM is online by entering the following command:

toaster> rlm status

Update the firmware by entering the commands described at Using the Data ONTAP CLI.

Note
Verify you are using the correct filename (filename.zip) of the RLM firmware.

Reboot RLM by entering the following command:

toaster> rlm reboot

Note
It takes approximately one minute for the RLM to reboot.

If the RLM does not reboot, repeat Steps 1 through 3. If the RLM still does not reboot, contact technical support for assistance.

Verify the RLM is online by entering the following command:

toaster> rlm status

From a browser, access the RLM firmware file on your Web server.

Note
Verify you are using the correct filename (filename.tar.gz) of the RLM firmware.

Update the firmware by entering the following command.

RLM toaster> rlm update http://path_hostname/RLM.FW.tar.gz

If this command fails, replace the path_hostname with the correct IP address.

Reboot the RLM by entering the following command:

toaster> rlm reboot
