External LU's capacity. When the mapped external LU's emulation type is for open systems, capacity
is displayed in 512-byte blocks. When the mapped external LU's emulation type is for mainframe
systems, capacity is displayed in cylinders.
NOTE:
When you use the Custom Volume Size (CVS) function to make an S-VOL for an XP Flex Copy
pair that has the same capacity as the P-VOL, set the S-VOL's capacity in blocks or cylinders
according to the emulation type.
• LDEV list
The status of external LU mapped as internal LDEV. The following information appears:
• CU:LDEV: CU:LDEV number of the internal LDEV to which the external LU is mapped.
• Path: Number of set paths.
• Emulation Type: External LU's emulation type set when it was mapped.
• Capacity: External LU's capacity.
• Status: External LU's status. Possible values: Normal, Unknown, Blockade, Warning, and
Format. Warning indicates that some alternate paths are blocked. Format indicates the external
LU is currently being formatted.
• View all LUs
Displays information about all external LUs in the LDEV list.
• 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.
