Well, once again "it depends"... you can adjust it (use CPFMTXA to change the cylinders allocated to "TEMP") on the fly. But CP only reads the allocation but map when the DASD is brought online.
Since TDISK are in your CP_Owned list, they can't be brought offline on a running system. So CP cannot re-read the allocation bit map to find the added or removed TEMP cylinders. (Note: CP does update bits in the allocation bits to indicate usage of the previously defined areas - so changing the use of previously allocated areas will end up with CP re-writing them anyway - not a good idea). You can add a while new volume for some purpose (temp disk, page, spool, etc.) on the fly, and CP can read that new DASD's bitmap when it comes online.
