8. Click OK.
The status of the external LU set in the LDEV Information window changes to Restore (restored),
and the external LU can be used in XP Command View Advanced Edition Software or Remote
Web Console.
If errors occur when changing the external LU's status, failed settings and error codes appear in
the Preset list. To check error messages, right-click the failed setting, and select Detail.
Displaying configuration information for external LUs (Volume Detail)
To display the Volume Detail window, right-click a row with an external LU from the LDEV list in the
LDEV Information window, and select Volume Detail (
Figure 57 ). If you select an external LU that is
a LUSE volume in the LDEV list, the Volume Detail window displays a list of all LDEVs that make up
the LUSE volume.
Figure 58 Volume Detail window
.
You can also check the LDEVs making up a LUSE volume by selecting View all Volumes at the bottom
of the LDEV Information window. However, only LDEVs in the specified external LU appear. The
Volume Detail window displays all LDEVs, including LDEVs of other external LUs.
The Volume Detail command is available after you restore the external LU using the Restore command.
Disconnecting external arrays or LUs
Use the Disconnect Subsystem and Disconnect Volume commands to disconnect external LUs. This is
necessary, for example, before turning off the power on local arrays or external arrays for maintenance
or before deleting an external LU's mapping.
The Disconnect Subsystem or Disconnect Volume command stops all host I/O to the mapped external
LU, and writes all data in the XP12000/XP10000/SVS200 cache memory to the external LU (all
data is destaged).
Mapping settings are preserved, even though the external LU is disconnected using the Disconnect
Subsystem or Disconnect Volume command. Therefore, you can resume using the external LU as a
mapped volume with the former settings. For instructions, see
Checking the connection status and
resuming external LU operations (Check Paths & Restore Vol.) .
