NetApp FAS User Manual

• 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.
• If you have a MetroCluster configuration, you must have confirmed that the MetroCluster Configuration
State is configured and that the nodes are in an enabled and normal state (
metrocluster node show).
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_downh
The following AutoSupport message suppresses automatic case creation for two hours: cluster1:*>
system node autosupport invoke -node * -type all -message MAINT=2h
2.
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 when prompted.
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.
Option 3: Controller is in a two-node MetroCluster
To shut down the impaired controller, you must determine the status of the controller and, if necessary, switch
over the controller so that the healthy controller continues to serve data from the impaired controller storage.
About this task
• If you are using NetApp Storage Encryption, you must have reset the MSID using the instructions in the
"Return a FIPS drive or SED to unprotected mode" section of
NetApp Encryption overview with the CLI.
• You must leave the power supplies turned on at the end of this procedure to provide power to the healthy
controller.
Steps
1. Check the MetroCluster status to determine whether the impaired controller has automatically switched
over to the healthy controller:
metrocluster show
2. Depending on whether an automatic switchover has occurred, proceed according to the following table:
