How would Partition Mobility work if the WPAR is part of the local root volume group?
With Partition Mobility (PM), the whole AIX image (what in WPAR terms many people also call the global AIX level) is moved to the new POWER6 machine. This will include all the WPAR details and content. Partition Mobility does this by moving the SAN disk connection and Network (both of which have to be via the Virtual I/O Server) to the new machine. For example, a WPAR using a file system in the rootvg or other volume group would move with the LPAR.
