View all Volumes
When the external LU is part of a LUSE volume, displays all LDEVs that make up the LUSE
volume in the LDEV list. However, LDEVs in other external LUs are not displayed, even though
those LDEVs might be part of the LUSE volume. To check all LDEVs configuring a LUSE volume,
use the Volume Detail command (see
Displaying configuration information for external LUs
(Volume Detail) ).
•
Previous and Next buttons
If you select multiple external LUs in the Device list in the LU Operation pane, click Previous
to change the LDEV list to the external LU appearing just above the currently displayed LU.
Click Next to change the LDEV list to the external LU appearing just below the currently
displayed LU.
•
OK button
Closes the LDEV Information window, and returns to the LU Operation pane. Contents specified
in the LDEV Information window appear in blue italics in the Device list, and settings appear
in the Preset list.

Cancel button
Cancels all setting operations, closes the LDEV Information window, and returns to the LU
Operation pane.
Restoring external LUs (Restore)
Use the Restore command to restore the status of external LUs.
When errors occur in all paths between the local array and external array, the local array changes
the status of the external LU to Blockade. In this case, see
Troubleshooting External Storage XP and
restore the path to the external array according to the troubleshooting instructions. 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 Restore command from the LDEV
Information window.
NOTE: If paths between the local array and external array are not restored, the external LU
cannot be restored to a usable status, even though you execute the Restore command.
NOTE: If you set a mainframe-system emulation type (such as 3390-3) when you mapped the
external LU, and you restore the mapped LU without formatting the LU or performing the Write to
Control Blocks operation, data in the volume cannot be read correctly.
1. Select the LU Operation tab. The LU Operation pane appears.
2. In the Device tree, select the external LU group number. Information about the external LU
mapped as an internal LDEV appears in the Device list.

The LDEV Information window appears. The LDEV list displays information about the external
LU selected in the Device list on the LU Operation pane.
