Ahhh, thanks.  In the test scenario, I have two different items, an
LPAR and a z/VM instance and both were configured with relatively
small disks. (6GB total).  The zVM one at least had a couple extra
DASDs added that I could add via LVM and that helped a lot.  The other
did not so I'm waiting for IS to expand it or give me more storage
somewhere.

Thanks a lot Colin
