Handover Overview
A handover is a controlled way to migrate all volumes associated with a particular volume collection to a replication partner without any loss of data. The new owner must be a downstream replication partner for replicas based on this volume collection.
When you perform a handover, the system displays a confirmation prompt. You can set up a CLI command to prevent the prompt from appearing. See the volcoll command in the Command Reference for more information.
The results of handing over a volume collection are:
- The volumes associated with the volume collection on this array are set offline.
- For snapshot replication only: Snapshots of the associated volumes are taken.
- For snapshot replication only: The snapshots are replicated to the downstream replication partner.
- Volume collection ownership is transferred to the replication partner.
- The volumes associated with the volume collection on the replication partner are set online.
- Schedules that apply to the other downstream partner halt.
By default, the direction of replication is automatically reversed. That is, when the downstream group becomes the owner of the volume collection, the upstream group becomes its replication partner.
