Shut down the impaired controller - AFF A200
To shut down the impaired node, you must determine the status of the node and, if necessary, take over the node so that the healthy node continues to serve data from the impaired node 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 node shows false for eligibility and health, you must correct the issue before shutting down the impaired node; see the Administration overview with the CLI.
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
Disable automatic giveback from the console of the healthy node:
storage failover modify –node local -auto-giveback false
Take the impaired node to the LOADER prompt:
If the impaired node is displaying… Then…
The LOADER prompt
Go to the next step.
Waiting for giveback…
Press Ctrl-C, and then respond
System prompt or password prompt (enter system password)
Take over or halt the impaired node:
For an HA pair, take over the impaired node from the healthy node:
storage failover takeover -ofnode impaired_node_name
When the impaired node shows Waiting for giveback…, press Ctrl-C, and then respond
If the system has only one controller module in the chassis, turn off the power supplies, and then unplug the impaired node’s power cords from the power source.
