Deleting external LU mappings (Delete LU)
You can start deleting external LU mappings from the LU Operation pane. To delete the external LU
mapping, select Delete LU from the shortcut menu displayed in the LU Operation pane. Although you
can use the Delete LU command to delete the mapping between an internal LDEV and external LU,
you cannot use this command to reliably delete data in the external LU or internal LDEV.
Before deleting the external LU mapping, notice if any of the following are true:
• Whether or not the execution of any application (for example, XP RAID Manager) that is using
the command device is in progress.
If any application using an external LU command device is executing, stop the application.
• Whether the Disconnect Subsystem or Disconnect Volumes command was executed.
All data in cache memory must be written into the mapped external LU using the Disconnect Sub-
system or Disconnect Volume command. For more information about the Disconnect Subsystem
and Disconnect Volume commands, see
Disconnecting external arrays or LUs .
• The volume is part of a LUSE volume.
• A path is set.
• The volume is configured as part of an XP Continuous Access, XP Continuous Access Journal, XP
Business Copy, or XP Snapshot pair.
• The volume is set as a reserved LU for XP Business Copy or XP Auto LUN.
• The volume is set as a pool-VOL.
If any of these conditions are true, you cannot delete the external LU mapping.
1. In the LU Operation pane, select the external LU group number in the Device tree. Information
about the external LU mapped as an internal LDEV appears in the Device list.
