Restoring external LUs (LDEV Restore)
The external LU's status might be blocked (Blockade) if errors occur during the setting operation or
the volume-formatting process fails. In this case, see
Troubleshooting External Storage XP and restore
the path to the external array according to the troubleshooting procedure. Then execute the Check
Paths & Restore Vol. command to make the external LU in Blockade status usable. If the external LU's
status remains Blockade, even though you restored the path to the external array and executed the
Check Paths & Restore Vol. command, execute the LDEV Restore command to restore the volume.
NOTE:
If the path between the local array and external array is not restored, you cannot restore the external
array's status to be usable, even though you execute the
LDEV Restore command.
NOTE:
You can also restore the external LU by executing the Restore command on the LDEV Information window.
