In the command output, you should see a message that the system ID has changed on the impaired node,
showing the correct old and new IDs. In the following example, node2 has undergone replacement and has
a new system ID of 151759706.

4. From the healthy node, 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 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 node:
a. From the healthy node, give back the replaced node’s storage:
storage failover giveback
-ofnode
replacement_node_name
the
replacement
node 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
