Re: z/VM 5.4; 6.1

[Jeff Gribbin]

Do you already have a z/VM system? If yes, you'll certainly have no
problem installing the new z/VM in a virtual machine using 3390-9
sized minidisks.  Then, once installed, you can DDR the packs onto the
starting cylinders of, 'dedicated' volumes (or even better, complete
the configuration work in the virtual machine, including changing the
volsers, before doing the DDR's so that you can't possibly get
duplicate volsers on the real system).
