> I think MAINT's 500 minidisk is only 600 cylinders and it may not be enough
We updated the "Servicing z/VM" chapter in the latest Virtualization Cookbook for SLES 11 (at the top of http://linuxvm.org/present/) If this is your problem, we ran into the same thing where the MAINT 500 disk ran out of space trying to apply a z/VM 5.4 RSU (is this z/VM 5.4?). We documented *one method* of creating a new disk to work around the issue. See section 5.2. Hope this helps. "Mike MacIsaac" <mike...@us.ibm.com> (845) 433-7061
