Deleting an LDEV (converting to free space)

You can convert one or more of the LDEVs on a selected parity group into free space by deleting
the LDEVs. That free space can be used to either create one or more variable-sized volumes (CVs)
using the Create LDEVs function, or left as free space for future use. You can also delete a system
disk if you no longer need it.

WARNING!

Deleting LDEVs will erase your data. Back up your data before deleting LDEVs.

An LDEV cannot be deleted successfully if it is:

In the defined path (including the pair volumes of Continuous Access Synchronous and
Continuous Access Journal).

A configuration element of LUSE.

A reserved volume of Auto LUN.

A pool-VOL (including LUSE).

A journal volume.

A remote command device.

A volume security volume.

A quorum disk.

An LDEV that has the Read/Write access attribute.

Online data migration volume.

An LDEV with the Volume Security for Mainframe setting.

When you delete an LDEV, the alias information contained in the LDEV is also deleted. Therefore,
if you delete an LDEV related to an alias device, you should do one of the following:

Allocate another LDEV to the alias device, and then delete the LDEV.

Delete the LDEV first, and then allocate another LDEV to the alias device.

For information about how to delete a registered external volume, see the HP XP P9000 External
