Troubleshooting RLM problems
Communication problems
If there is a communication failure between the storage system and the RLM, search for EMS events titled:
[rlm.orftp.failed:warning]: RLM communication error, (reason)
Configuration problems
If you are having difficulty configuring the RLM, view detailed configuration information and assign a new IP address by completing the following steps.
Step
|
Action
|
|
1
|
Verify the RLM is online and the IP configuration is correct by entering the following command:
toaster*> rlm status
|
|
2
|
If the RLM is configured using DHCP, reconfigure the RLM using a static IP address by entering the following command:
toaster*> rlm setup
|
Connection problems
If you are having difficulty connecting to the RLM, check the connection by completing the following steps.
Step
|
Action
|
|
1
|
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.
|
|
2
|
From the storage system, verify the RLM is online and the IP configuration is correct by entering the following command:
toaster> rlm status
|
|
3
|
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.
|
|
4
|
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.
|
|
5
|
If the RLM does not reboot, repeat Steps 2 through 4. If the RLM still does not reboot, contact technical support for assistance.

RLM failures
An RLM failure can occur for one of the following reasons:
- A communication link between the RLM and the storage system is broken.
- A hardware failure has occurred on the RLM.
If the RLM fails, search for EMS events titled:
[rlm.heartbeat.stopped:warning]: Have not received a Heartbeat from
the Remote LAN Module in the last n seconds, (reason)
To troubleshoot an RLM failure, complete the following steps.
Step
|
Action
|
|
1

|
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.

RLM firmware update problems
A firmware update failure can occur for one of the following reasons:
- The firmware image is incorrect or corrupted.
- A communication error occurred while sending firmware to the RLM.
- The update failed when you attempted to install the new firmware at the RLM.
- The storage system was reset during the update.
- There was a power loss during update.
To troubleshoot a firmware failure, search for EMS events titled:
[rlm.orftp.failed:warning]: RLM firmware update failed, (reason)
Example
[rlm.orftp.failed:warning]: RLM firmware update failed:
ORFTP couldn't send info.symlinks to RLM.
This error message indicates that the firmware update failure is due to a communication error.
Troubleshooting with the Data ONTAP CLI.
To troubleshoot updating the firmware using the Data ONTAP CLI, complete the following steps.
Step
|
Action
|
|
1
|
Verify the RLM is online by entering the following command:
toaster> rlm status
|
|
2
|
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.
|
|
3
|
Reboot RLM by entering the following command:
toaster> rlm reboot
Note It takes approximately one minute for the RLM to reboot.
|
