An HA pair |
After the impaired node is displaying the Waiting for Giveback...
message, perform a giveback from the healthy node:
- Perform a giveback from
the healthy node: storage failover giveback -ofnode
partner_node_name
This
initiates the process of returning ownership of the impaired
node's aggregates and volumes from the healthy node back to
the impaired node.
- Monitor the progress of
the giveback operation by using the storage
failover show-giveback command.
- After the giveback
operation is complete, confirm that the HA pair is healthy and
that takeover is possible by using the storage failover show command.
- Restore automatic
giveback if you disabled it by using the storage failover modify command.
