Lucky me, it's the same here (automation product starts and stops JES2).
As long as the volume I'm talking is not the one and only spool volume to that 
LPAR, can I take a chance by just using the VARY command from COMMND00.

Worst case, what'll happen... I'll see a prompt of some sort in the NIP 
console, asking for REPLY DEVICE NAME OR CANCEL.. or some such?

From my experience in various shops, I'd say that it's unusual not to have all 
JES2 volumes online at IPL. Timing is the key issue. As long as all needed 
volumes are online at JES2 start, then there is no problem. If JES2 cannot find 
a volume that CHECKPOINT says is needed, then there will be intervention 
required.

One question is how you start JES2. We have this in IEFSSNxx:

SUBSYS SUBNAME(JES2)
  PRIMARY(YES)  START(NO)

This means that automation (in our case Netview SA) will start JES2 at a point 
we choose. Even if you have START(YES), I would think that the VARY command 
would execute first. However device manipulation commands can get delayed 
especially during early IPL. No point in taking chances.

'at IPL time' in this context can be detailed further. The volume must be 
online at JES2 starttime, which is a little later than IPL time.
