Replace the NVMEM battery - AFF A150
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
When you see Do you want to disable auto-giveback?, enter y.
3. Take the impaired controller to the LOADER prompt:
