6. On the source system - Remove the VLUN exports to the destination system from the source
system.
7. On the source system - Remove the host representing the destination system from the
source system.
If a failure occurs after volume import tasks have started, the hosts' access to the volumes on the
source system will have been interrupted. A failed import returns the system to the point where the
import can be retried after the cause of failure is resolved. A full rollback to the system state before
the volume import failure is possible.
To return the system to its state before a volume import failure:
1. On the host - Cleanly stop access to the destination system from the host. The host will lose
access to the volumes being migrated. To prevent consistency issues, any active applications
should be cleanly shutdown.
2. On the destination system - Remove the VLUNs on the destination system for the volumes
exported to the host.
3. On the destination system - Remove the admitted volumes from the destination system.
4. On the destination system - Remove the host from the destination system.
5. On the source system - Remove the VLUN exports to the destination system from the source
system.
6. On the source system - Remove the host representing the destination system from the source
system.
7. On the source system - Issue the setvv – clralua CLI command for the volumes that were
being migrated and that are in "standby" state in the VLUN table.
8. On the fabric and host - Rezone the host back to the source system.
9. On the fabric and host - Restart the host and any applications that were shutdown at the
beginning of this process.
