4. From the healthy controller, verify that any coredumps are saved:
a.
Change to the advanced privilege level:
set -privilege advanced
You can respond Y when prompted to continue into advanced mode. The advanced mode prompt
appears (*>).
b.
Save any coredumps:
system node run -node local-node-name partner savecore
c. Wait for the `savecore`command to complete before issuing the giveback.
You can enter the following command to monitor the progress of the savecore command:
system
node run -node local-node-name partner savecore -s
d.
Return to the admin privilege level:
set -privilege admin
5. Give back the controller:
a.
From the healthy controller, give back the replaced controller’s storage:
storage failover
giveback -ofnode replacement_node_name
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 content 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:
260
