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” on page 121 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. For more information, see ”Restoring external LUs (Restore)” on page 96.
Restoring volumes in an external array

Restore.
The selected external array appears in blue italics in the Device tree and Device list. The contents of the
setting appears in the Preset list. To check setting details, right-click the setting in the Preset list, and
select Detail. To cancel the setting, right-click the setting in the Preset list, and select Delete.
3. Click Apply. A confirmation message appears.

For the external LUs of the selected external array, the Status column of the Device list changes to the

When errors occur during a status change for the external LU, the failed setting and error code appears
in the Preset list. To check the error message, right-click the failed setting, and select Detail.
