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? – Vignesh Mainframe Infrastructure -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Jesse 1 Robinson Sent: 19 November 2018 17:16 To: [email protected] Subject: [EXTERNAL] Re: Spool volume 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. . .

The volume must be online at JES2 starttime, which is a little later than IPL time.
