Chapter 4. File module

This topic provides information about troubleshooting the file module, which
includes error codes, problem scenarios, software troubleshooting, and removal
and replacement instructions.

General file module procedures

This section covers file module general maintenance and repair issues.

Rebooting a file module

Use this procedure to initiate a file module reboot.
Events can occur on a file module that require the hardware to be rebooted.
1. Verify that the file module that the reboot is to be performed against is the
2. Log in to the active management node.
3. Shut down and reboot the passive node by using the following CLI command:
4. The node reboot restarts all services that were previously running.

Removing a file module to perform a maintenance action

You can remove an IBM Storwize V7000 Unified file module to perform
maintenance. The procedure that you follow differs slightly, depending on whether
you must unplug the power cables.
If you receive an alert event that requires you to service a file module, use the
following procedure to remove the file module from the system and perform the
required service.
Some field replaceable units (FRUs) are redundant and hot swappable, such as
power supplies. When replacing a hot-swap FRU, you have the option of leaving
the file module turned on and the power cables connected. Always follow the
remove and replace procedure for the FRU. The procedure for the FRU indicates
whether the FRU is hot swappable.
If the removal and replacement procedure does not indicate whether the FRU is
hot swappable, assume that it is not. In that case use the file module-removal
procedure that requires you to disconnect the power cords.
Note: Before removing an file module, you must suspend the file module.
