4.2.3 Deleting a VLL volume

To delete an individual Virtual LVI/LUN volume within an LDEV or parity group, use the

volume to space operation (refer to section 4.2.1).

To convert a Virtual LVI/LUN volume to a normal volume, you must initialize the volume (see

section 4.2.4).

4.2.4 Initializing a Virtual LVI/LUN Volume

WARNING: The Volume Initialize function is a destructive operation. The data on the Virtual

LVI/LUN volume being converted will be lost when the operation is complete. The user is

responsible for backing up the data as needed before performing this operation.

The Volume Initialize function allows you to convert a Virtual LVI/LUN volume back to a

normal volume. This operation de-installs all variable sized volumes under a Virtual LVI/LUN

volume and then reformats the Virtual LVI/LUN volume as a normal volume (e.g., 3390-3).

The Volume Initialize operation has the following restrictions:

 The LDEV should not have a path definition (including Hitachi TrueCopy-S/390, Hitachi

TrueCopy, ShadowImage-s/390, and ShadowImage pair volumes).

 The LDEV should not be a component of a LUSE volume.

 The LDEV should not be reserved for Hitachi CruiseControl.
