You can cutover an import when the import session reaches the
Ready For Cutover state. After cutover, the source volume, LUN, or consistency group is no longer accessible to the associated hosts and the
PowerStore cluster.
The following steps show the manual import workflow in
PowerStore Manager:
Select the import session to cutover.
Select the
Cutover import action to cutover to the
PowerStore cluster. The following cutover processing occurs:
Forwarding of host I/O from the
PowerStore cluster to the source system stops.
The volume or volume group status updates to
Import Complete upon successful cutover.
NOTE:When all the volumes in a volume group are cutover successfully, the state of the import session is set to
Import Complete. However, since the status of the volume group depends on the final status of the member volumes, if one or more of the member volumes are in a state other than
Import Complete, the status of the volume group is set to
Cutover_Failed. Repeat the cutover operation again until it succeeds and the status for the volume group becomes
Import Complete.
Hosts and
PowerStore cluster access to the source volume, LUN, or consistency group is removed.
NOTE: Import sessions are not deleted. If you want to delete the import session, use the delete operation that is available only through the REST API. For more information about the REST API, see the
PowerStore REST API Reference Guide.
