Unsparing operation on the PV can be done as follows:

# pvchange -z n /dev/dsk/c3t2d0

this makes /dev/dsk/c3t2d0 a regular PV which can be vgreduce'ed out of vg00. To move PRDu01 onto vg01 create a large enough lvol on vg01; backup and unmount PRDu01; restore PRDu01 data from backup onto the vg01 lvol.

Ok, Thanks in advance, but I thinks that first I reduce the logical volum, and other thing, I need the action plan, because I don't know unix, please, thanks for all.
