Volume to Space function
This function converts one or more LDEVs (FVs or CVs) into free space, which deletes the selected LDEVs
from that VDEV.
The following are the restrictions on LDEVs and LUSE volumes for the Volume to Space operation:
• The LDEV must not be path-defined (including TrueCopy for z/OS, Continuous Access XP,
ShadowImage for z/OS, Business Copy XP, and Continuous Access XP Journal pair volumes).
• The LDEV must not be a component of a LUSE volume.
• TheLDEVmustnotbereservedforAutoLUNXP.
