Varying the disks off of LPAR 1 and then varying them on LPAR 2 makes the assumption that both LPARs share the same DASD. This is often, but not always the case. Do your two LPARs share the same DASD (and use the same rdev's - which is almost always the case when they are shared)? If so, then the methodology that Rogerio describes, which does a move not a copy, will work. If not, you will need to copy the data somehow.
