NetApp AFF A Series User Manual

• If you are using NetApp Storage Encryption, you must have reset the MSID using the instructions in the
Returning SEDs to unprotected mode.
•
If you have a SAN system, you must have checked event messages (
cluster kernel-service show)
for impaired controller SCSI blade. The
cluster kernel-service show command displays the node
name, quorum status of that node, availability status of that node, and operational status of that node.
Each SCSI-blade process should be in quorum with the other nodes in the cluster. Any issues must be
resolved before you proceed with the replacement.
• 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
Synchronize a node with the cluster.
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
When you see Do you want to disable auto-giveback?, enter y.
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
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.
Step 2: Remove the controller module
You must remove the controller module from the chassis when you replace the controller module or replace a
component inside the controller module.
1. If you are not already grounded, properly ground yourself.
2. Unplug the controller module power supplies from the source.
