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
.
Option 2: Controller is in a MetroCluster
Do not use this procedure if your system is in a two-node MetroCluster 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
.
• 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:
62
