All other components in the system must be functioning properly; if not, you must contact technical support.
You must replace the failed component with a replacement FRU component you received from your provider.

Step 1: Shut down the impaired controller
Shut down or take over the impaired controller using different procedures, depending on the storage system
hardware configuration.
To shut down the impaired controller, you must determine the status of the controller and, if necessary, take
over the controller so that the healthy controller continues to serve data from the impaired controller storage.
If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a healthy
controller shows false for eligibility and health, you must correct the issue before shutting down the impaired
controller; see the
Administration overview with the CLI
.
Steps
1. If AutoSupport is enabled, suppress automatic case creation by invoking an AutoSupport message:
system node autosupport invoke -node * -type all -message
MAINT=_number_of_hours_down_h
The following AutoSupport message suppresses automatic case creation for two hours:
cluster1:*>
system node autosupport invoke -node * -type all -message MAINT=2h
2. If the impaired controller is part of an HA pair, disable automatic giveback from the console of the healthy
controller:
storage failover modify -node local -auto-giveback false
3. Take the impaired controller to the LOADER prompt:
If the impaired controller is
displaying…
Then…
The LOADER prompt
Go to Remove controller module..
Waiting for giveback…
Press Ctrl-C, and then respond
y
.
System prompt or password
prompt (enter system password)
Take over or halt the impaired controller from the healthy controller:
storage failover takeover -ofnode
impaired_node_name
+
When the impaired controller shows Waiting for giveback…, press
Ctrl-C, and then respond
y
.
4. If the system has only one controller module in the chassis, turn off the power supplies, and then unplug
the impaired controller’s power cords from the power source.
Step 2: Remove controller module
To access components inside the controller, you must first remove the controller module from the system and
then remove the cover on the controller module.
