Cancel |
NOTE:For volume, Cancel can be performed only when the import processing state is
Queued,
Scheduled,
Ready To Enable Destination Volume,
Ready to Start Copy,
Copy In Progress,
Paused,
Ready For Cutover, or
Cancel Required, and the host application that is accessing the volume has been shutdown and reconfigured to access the source volume. For volume group, Cancel can be performed only when the import processing state is
Queued,
Scheduled,
In Progress,
Paused,
Ready For Cutover,
Import Cutover Incomplete,
Cancel Required,
Cancel Failed,
Failed and the host application that is accessing the volume has been shutdown. Before cancelling an agentless import session, reconfigure the host application that is accessing the import's destination volume back to the source volume. This action is applicable when the import session is being cancelled after the host application has been reconfigured to use the destination volume in
PowerStore.
Select an import session and under
Import Actions, click
Cancel. The cancel operation sets the state of the import session to
CANCELLED and disables access to the destination volume. It also deletes the destination volume or volume group that is associated with the import session.
NOTE:When all the volumes in a volume group are cancelled successfully, the state of the import session is set to
CANCELLED. 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
CANCELLED, the status of the volume group is set to
Cancel Failed. Repeat the cancel operation again until it succeeds and the status for the volume group becomes
CANCELLED.
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. Manual intervention is required to reconfigure the host to access the source volumes again.
NOTE:A
Force Stop option is not available for Cancel during an agentless import.

Cutover |
NOTE:Before performing the cutover, ensure that you can access your data as expected. You cannot revert after this step.
Select an import session and under
Import Actions, click
Cutover to commit an import session. You can cut over an import session that is in the
Ready For Cutover state.
NOTE:When all the volumes in a consistency group are cut over successfully, the state of the import session is set to
Import Complete. However, since the status of the consistency 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 consistency group is set to
Cutover_Failed. You must remove all the failed volumes from the consistency group and try the import again.
NOTE:After performing the cutover, ensure to remove the host mappings of the source volume in the source array. Also, after one set of imports is completed, run the next set of imports after a delay of 10 minutes. This delay allows enough time for the system to cleanup any connections to the source system.

Pause |
Select an import session and under
Import Actions, click
Pause. Use
Pause to pause an import session that is in the
Copy In Progress state.
NOTE:The Pause import action on a CG only pauses the member volumes that are in the
Copy In Progress state. The CG remains in the
In Progress state. Other member volumes that are in other states, such as
Queued or
In Progress, are not paused and may proceed to the
Ready For Cutover state. The other member volumes can be paused when they reach the
Copy In Progress state by using the Pause import action again on the CG. If any of the member volumes are in the
Paused state but the overall status of the CG is
In Progress, both the Pause and Resume import action options are available for the CG.
