To display the Volume Detail window, select a row with an external LU from the LDEV list in the LDEV
Information window, right-click, and select Volume Detail. 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.
You can also check the LDEVs making up a LUSE volume by selecting View all Volumes at the bottom of the
LDEV Information window. This option displays only the LDEVs emanating from the specified external LU.
The Volume Detail window lists all LDEVs, including those of other external LUs.
NOTE: The Volume Detail command is available after you restore the External Storage XP volume using
the Restore command.
Disconnecting external disk arrays or external LUs
Use the Disconnect Subsystem and Disconnect Volume commands to disconnect external LUs. This is
necessary, for example, before you turn off the power supply of the local disk arrays or external disk arrays
for maintenance or before deleting an external LU’s mapping.
When you execute the Disconnect Subsystem or Disconnect Volume command, External Storage XP stops
all host I/O to the mapped external LU, and all data in the XP10000/XP12000 cache memory is written
to the external LU (all data is destaged).
