I think someone mentioned this recently, but one way to do this is to put only the system-owned volumes in the online-at-ipl statement, and then vary on and attach the appropriate volumes in AUTOLOG1 (or your equivalent) before you start autologging machines. It's easier to modify the list there instead of the somewhat cumbersome process of messing with SYSTEM CONFIG (and possibly creating a unbootable system).

(CMS/CTR) (CTR) Sent: Friday, September 03, 2010 6:30 PM To: IBMVM@LISTSERV.UARK.EDU Subject: DEVICES Statement in SYSTEM CONFIG Hi On my system all of the devices come online at IPL time. So if I only want certain devices to come online on certain LPARS can I do something like this where since all of the devices come online at IPL can I vary them all offline and then come back and issue the online command for only the volumes I want online for this LPAR. If there is a better way please by all means let me know!
