What happens during giveback

The local node returns ownership of the aggregates and volumes to the partner node after any issues on the partner node are resolved or maintenance is complete. In addition, the local node returns ownership when the partner node has booted up and giveback is initiated either manually or automatically.

The following process takes place in a normal giveback. In this discussion, node A has taken over node B. Any issues on Node B have been resolved and it is ready to resume serving data.

1. Any issues on node B have been resolved and it is displaying the following message:
   Waiting for giveback
2. The giveback is initiated by the storage failover giveback command or by automatic giveback if the system is configured for it.

   This initiates the process of returning ownership of the node B's aggregates and volumes from node A back to node B.

3. Node A returns control of the root aggregate first.
4. Node B proceeds to complete the process of booting up to its normal operating state.
5. As soon as Node B is at the point in the boot process where it can accept the non-root aggregates, Node A returns ownership of the other aggregates one at a time until giveback is complete.

   You can monitor the progress of the giveback with the storage failover show-giveback command.

I/O resumes for each aggregate once giveback is complete for that aggregate, therefore reducing the overall outage window of each aggregate.
