I had an unexpected occurrence this past weekend. I needed to add to 2
volumes to the cp owned list in the SYSTEM CONFIG file. I try to keep
the list in volume order. I inserted the two volumes and thus pushed
everything else down on the list, thus changing the slot assignment. Of
the volumes that got shifted to new slots were two volumes I use for
spool packs. Everything went smoothly until I IPL'd. When VM came back
up, at the point after you reply with resetting the TOD, VM fussed about
the spool packs and asked if I wanted to delete all the entries in the
spool file.
This came as a complete surprise to me. I didn't know VM, or whatever,
keep track of slots and what they were assigned to. I replied stop,
hoping that it would ignore the problem and go on. Nope, VM does stop.
Luckily I had a mini VM system installed for DR testing and was able to
get the problem corrected.
My question is: does VM keep track of slot assignments? I wouldn't
think so, but . . .
Below are three versions of the config files. The first one is the
original before I started moving things around.
CP_Owned Slot 1 540RES
CP_Owned Slot 2 540SPL <--- spool pack
CP_Owned Slot 3 540PG1
CP_Owned Slot 4 540W01
CP_Owned Slot 5 540W02
CP_Owned Slot 6 540W03
CP_Owned Slot 7 540W04
CP_Owned Slot 8 540W05 <--- spare entry. I always keep one
spare entry in the list. Volume didn't exist at this point in time.
CP_Owned Slot 9 VMWRK1 <--- spool pack
CP_Owned Slot 10 VMWRK2
CP_Owned Slot 11 VMWRK3 <--- spool pack
CP_Owned Slot 12 VMWRK4
CP_Owned Slot 13 540PG2
CP_Owned Slot 14 540PG3
CP_Owned Slot 15 RESERVED
CP_Owned Slot 16 RESERVED
CP_Owned Slot 17 RESERVED
CP_Owned Slot 18 RESERVED
CP_Owned Slot 19 RESERVED
CP_Owned Slot 20 RESERVED
This next one is where I inserted the two new volumes and shifted the
volumes below down to new slots. This version of the list is what
caused the problems.
