Rhetorical question: When, oh when, will IBM document adding PAGE and SPOOL volumes dynamically in a clear, concise manner?
This question is asked at least 3 or 4 times per year. And more often as we get more new z/VM sysprogs (WELCOME!). None of the lengthy calculations used to determine the initial PAGE and SPOOL volumes apply when someone wants to dynamically add a volume. The answer is always the same - and pretty simple (but scary to the uninitiated, and their managers). "Just DO IT"! :-) To answer your question: It is to adding a PAGE volume dynamically. One important caveat. -------------------------- When you add the SLOT to CP_OWNED in SYSTEM CONFIG, you don't ever get to change the SLOT number without first scheduling stand-alone time to use SPXTAPE to backup ALL your SPOOL files (including all SDF's -System Data Files, e.g CMS and many more). And I mean NEVER change a SPOOL volume SLOT number, not even "by accident" when you're doing regular "housekeeping" to neaten up the SYSTEM CONFIG file sometime in the future. That's why in my SHARE session "z/VM Installation - It's Installed, NOW What? (or: What we learned "on the Job")" (http://linuxvm.org/Present/SHARE111/S9120mw.pdf see slides 12-14) I recommend when installing z/VM to place the SPOOL volumes at the top of the CP_OWNED list -- and documenting why they should not be moved without understanding the implication of changing a SLOT number (loss of "*ALL* SPOOL files). So, to cut/paste from Scott Wandschneider's posts of just last week asking about a dynamic PAGE volume addition, adjusting for SPOOL: 1) CP ATTach rdev to MAINT. 2) CPFMTXA FORMAT 0-end on a new volume, with your chosen volser. 3) ALLOCATE 0-0 PERM and 1-END SPOL. additions... 4) Update SYSTEM CONFIG with new CP_OWNED SPOOL volume. Remember the SLOT number. (see comments above about never changing the SLOT number - maybe you want to slip it in right after an existing SPOOL SLOT if there's room available). 5) Run CPSYNTAX (on MAINT's 193 disk) against the updated SYSTEM CONFIG (as usual, after any change). 6) DETach rdev (from MAINT) 7) ATT rdev SYSTEM volser 8) CP DEFINE CPOWNED SLOT nnnn volser OWN (nnnn=SLOT number from SYSTEM CONFIG) 9) CP START DASD rdev SPOOL 10) CP Q ALLOC SPOOL (check that the new volume it looks right) Let me us know if I left anything out (detailed instructions were obviously not included for CPFMTXA, or updating SYSTEM CONFIG). Maybe IBM can use the results for a simple update to "CP Planning and Use".
