Step 5. The next step depends on your system configuration:
If your system is in...
Then...
An HA pair
After the impaired node is displaying the
Waiting for Giveback... message, perform a
giveback from the healthy node:
1. Perform a giveback from the healthy node:
storage failover giveback -ofnode partner_

This initiates the process of returning
ownership of the impaired node's
aggregates and volumes from the healthy
node back to the impaired node.
Note: If the giveback is vetoed, you can
consider overriding the vetoes.
If giveback
is vetoed
2. Monitor the progress of the giveback

4. Restore automatic giveback if you
disabled it by using the
storage failover
modify command.
