The replacement controller takes back its storage and completes booting.
If you are prompted to override the system ID due to a system ID mismatch, you should enter
y.
If the giveback is vetoed, you can consider overriding the vetoes.
Find the High-Availability Configuration Guide for your version of ONTAP 9
b. After the giveback has been completed, confirm that the HA pair is healthy and that takeover is
possible:
storage failover show
The output from the storage failover show command should not include the System ID changed
on partner message.
6.
Verify that the disks were assigned correctly:
storage disk show -ownership
The disks belonging to the replacement controller should show the new system ID. In the following
example, the disks owned by node1 now show the new system ID, 1873775277:
node1> `storage disk show -ownership`
Disk Aggregate Home Owner DR Home Home ID Owner ID DR Home ID
Reserver Pool
----- ------ ----- ------ -------- ------- ------- -------

7.
Verify that the expected volumes are present for each controller:
vol show -node node-name
8.
If you disabled automatic takeover on reboot, enable it from the healthy controller:
storage failover
modify -node replacement-node-name -onreboot true
Restore Storage and Volume Encryption functionality
After replacing the controller module or NVRAM module for a storage system that you
previously configured to use Storage or Volume Encryption, you must perform additional
steps to provide uninterrupted Encryption functionality. You can skip this task on storage
systems that do not have Storage or Volume Encryption enabled.
Step
1. Restore Storage or Volume Encryption functionality by using the appropriate procedure in
NetApp
Encryption overview with the CLI.
