Vsc Operations - HP StorageWorks XP128 User Manual

If the XP disk array has firmware version 21.06.22 or later installed, you can reset an unregistered LUSE
volume to the state before it was created. However, you cannot recover any LUSE volumes that have been
released already to the state when they were created. If the LUSE volume that you have created consists of
any LDEVs (those in blue bold italics) that have once been released from a different LUSE volume, you can
only reset your LUSE volume to the state when the constituting LDEVs were released from the other LUSE
volume.
1. In the Volume Management pane, select the CU number from which you want to reset an unregistered
LUSE volume. The LDEV Information table shows all LDEVs that the selected CU contains.
2. In the LDEV Information table, right-click an unregistered LUSE volume (displayed in blue bold italics)
and select Reset Selected Volume. A confirmation message appears.
3. Verify the information in the dialog box and click OK. The unregistered LUSE volume will be reset to the
state before this LUSE volume was created. The LDEV Information table displays the LUSE volumes or the
LDEVs constituting the selected LUSE volume that has just been reset.

Parity Group - LDEV tree
This tree shows a hierarchical structure of a disk group number (Box 1), parity group numbers (for
example, 1-1), RAID levels (for example, 3D+1P), and VDEV numbers (for example, 1-1-1).
An LDEV number that ends with a # indicates that the LDEV is an external LU (for example, 00:01#).
The RAID level is left unspecified with a hyphen (-) when the LDEV is an external LU.
