File module software problems

This section helps you to identify and resolve file module software problems.
About this task

Logical devices and physical port locations

Use this table to help identify logical devices, file module roles used, and physical
locations.

Management node role failover procedures

The following procedures either restart the management service or initiate a
management service failover from the file module hosting the active management
node role to the file module hosting the passive management node role.
Once complete, the file module that previously hosted the active management
node role now hosts the passive management node role. The file module that
previously hosted the passive management node role now hosts the active
management node role.
Note: All of these tasks require a user that is configured as a CLI admin. Other
users cannot perform these tasks.
Determining the service IP for the management node roles
Use this procedure to identify the service IP addresses for the file modules that
host the management node roles.
About this task
You need the service IP address of a file module that hosts a management node
role to perform a management failover from the file module that hosts the active
management node role to the file module that hosts the passive management node
role, when the active management node fails and the current management IP does
not respond.
Connect to imm to reboot.
Issuing reset command to imm.
Checking if the imm has reset yet. (attempt 0)
imm has started the reset.
Disconnect from imm
b. Wait for about 2 minutes to allow the iMM to completely reboot.
