• You must be replacing a controller module with a controller module of the same model type. You cannot
upgrade your system by just replacing the controller module.
• You cannot change any drives or drive shelves as part of this procedure.
• In this procedure, the boot device is moved from the impaired controller to the
replacement
controller so
that the
replacement
controller will boot up in the same version of ONTAP as the old controller module.
• It is important that you apply the commands in these steps on the correct systems:
◦
The
impaired
controller is the controller that is being replaced.
◦
The
replacement
controller is the new controller that is replacing the impaired controller.
◦
The
healthy
controller is the surviving controller.
• You must always capture the controller’s console output to a text file.
This provides you a record of the procedure so that you can troubleshoot any issues that you might
encounter during the replacement process.
Shut down the controller - FAS2600
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
