If automatic giveback was disabled, reenable it:
storage failover modify -node local
-auto-giveback true
== Step 5: Return the failed part to NetApp
Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the
Part
Return & Replacements
page for further information.
= Replace the NVMEM battery - ASA C250

To replace an NVMEM battery in the system, you must remove the controller module
from the system, open it, replace the battery, and close and replace the controller
module.
All other components in the system must be functioning properly; if not, you must contact technical
support.
== Step 1: Shut down the impaired controller
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.
About this task
• 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
