The issue is not rebooting gcc119 AIX VM or wiping out the AIX /home filesystem. To expand the VIOS partition I need to reboot the hypervisor host and all of the AIX partitions, which is more difficult to schedule. Also, there does not appear to be a mechanism to squeeze down the physical volume on the disk array and carve out new devices. Thanks, David
