Looks safe, but… In our plan to test a new release of VSE (3.1)
we plan to isolate a copy of our production VM system as a 2ndlevel

would give us duplicate volsers for all the volumes in the System
Config. If we specify the address range of the ‘restored’ dasd as
‘Offline_at_IPL’ are we assured that this statement will be
processed/respected before the Ipl proceeds so we will not
encounter CP picking up our ‘restored’ volume instead of the real
production volume?
Yes.
That said, it still makes me twitchy to do so: some day, someone,
somewhere, is going to delete those statements from SYSTEM CONFIG.
You're better off, if you can arrange it, clipping the disks...but if
the last cylinder of your disks is in use, that doesn't work.
At the very least put in a comment in SYSTEM CONFIG explaining *why*
those volumes are Offline_at_IPL.
