Hi Ranga: Do your second level VM system packs start on real cylinder 0? z/VM will install just fine to a full pack minus one cylinder so I recommend having your second level system use mdisks that start on real cylinder 1. So you can label your 2nd level systems ZVM520 if you want to - and label cylinder 0 something that makes your DASD managers happy.

I need to relabel the volumes for my 2nd level z/VM, which is our test environment. This is something coming from our z/OS sysprogs. Is there any way to change all references to volume label using some utility? If not where all would I need to change the volume labels? I can think of SYSTEM CONFIG, extent control (dont remember how to access this) and the directory entries.
The DASD at 2nd level does not share any DASD with level 1.
Appreciate your help.
