After activated by TLMSRIM, the CA TLMS WTO subsystem passes control to CA TLMS for all tape mount messages. If the mount request is nonspecific and requires a tape from a specific pool, the mount message is modified to include the tape pool identification (up to 13 characters). If the mount request is specific, the mount message reflects the location of the volume, and whether it is a CA TLMS controlled volume.
In all cases, a reissued operating system mount message is prefixed with a CA TLMS message identification to notify the operator that the intercept is present and functioning. The original and reissued WTO appears on the SYSLOG and JESLOG; only the new WTO is displayed on the console.
On a system console, a nonpool mount message is prefixed with CTS001, while a pool-controlled mount is prefixed with CTS002.
For example, a MINIREEL scratch pool is assigned the range, MI0001-MI9999, and data sets using a high-level alias of MINI are authorized to write to the MINIREEL pool. When the mount request is issued, CA TLMS modifies the mount message to read:
*CTS002 IEF233A M 05A0,MINIREEL,SL,6250,JOBNAME,STEP1,MINI.DATASET.NAME
For tape mounts not reflecting a data set name prefixed with MINI, the mount message reads:
*CTS001 IEF233A M 05A0,SCRTCH,SL,6250,JOBNAME,STEP1,NON.MINI.DATASET.NAME
JES3 messages use the prefix CTS004 for non-pool mount messages, and CTS005 for pool-controlled mounts.
Note: If using STK silos, you must have an entry coded above the STK silo entry in the subsystem name table. The entry is TLMS.
