Dell PowerStore Importing External Storage to PowerStore Guide

Cancel workflow for agentless import

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.

The following steps show the manual cancel workflow in PowerStore Manager:

1. Select the import session to cancel.
2. Select the Cancel import action to cancel the import session.
3. 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:
   1. The destination volume is disabled.
   2. 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.
   3. The destination volume is deleted.
