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. 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, or Failed. Before cancelling an agentless import session, shut down the host application and reconfigure the host application that is accessing the import's destination volume or volumes back to the source volume or volumes. Shutdown of and reconfiguring the host application is applicable only when the import session is being cancelled after the host application has been reconfigured to use the destination volume in
PowerStore.
The cancel operation sets the state of the import session to
CANCELLED and disables access to the destination volume or volume group. It also deletes the destination volume or volume group associated with the import session.
NOTE:A
Force Stop option is not available for Cancel during an agentless import.
The following steps show the manual cancel workflow in
PowerStore Manager:
Select the import session to cancel.
Select the
Cancel import action to cancel the import session.
Click
CANCEL THE IMPORT in the pop up screen.
NOTE:To enable
Cancel The Import, check the checkbox to confirm that the host application has been shutdown or taken offline.
The following cancel processing occurs:
The destination volume is disabled.
The state of the import session is set to
CANCELLED on the successful completion of the operation.
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 is dependent 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. You must repeat the cancel operation again until it succeeds and the status for the volume group becomes
CANCELLED.
The destination volume is deleted.
NOTE:Import sessions are not deleted but can be deleted through the REST API. Manual intervention is required to reconfigure the host to access the source volumes again.
