Thanks, I changed some locations but none dealing with spool. So I should be ok with a WARM start. I think I will take your advice and RESERVE the SLOTS right after the last spool for additional spool. BTW, is there a practical limit on the number of SLOTS that can be defined?

To get the list of all disks that contain spool areas the way the running system sees them, do CP Q ALLOC SPOOL. If you changed the order of disks that contain spool areas, the safest way to go is to backup the spool with SPXTAPE DUMP, do CLEAN start, restore the spool with SPXTAPE LOAD and re-IPL the system. COLD start erases all ordinary spool files but leaves SDF files which you don't want to lose. If you change the order of the spool packs, doing COLD start may not save you - you can still lose some SDF files and Murphy's law says that CMS NSS will be one of them. CLEAN start erases everything and, if you are in a hurry, you *have* to restore at least SDF files (use SDF option of SPXTAPE LOAD) and re-IPL to have the system the way you know it. You can then restore the rest of the spool (RDR, PRT and PUN files) at your leisure. One more word of warning: immediately after CLEAN start, you will not have CMS NSS, so you will not be able to IPL CMS anywhere. Use IPL 190 instead. Ivica
