CA TLMS lets you use any combination of tape volume serial numbers, as long as each volume serial number is unique. Volume serial numbers may be from one to six alphabetic or numeric characters. For example, 11223, A1A222.
All volume serial numbers in the VMF are six characters. If you have tapes with a VSN of five or less characters, use the VSNPAD option to extend the VSN to six characters. The VSNPAD option specifies a character that left pads the tape VSN to make it six characters in length.
For example, VSNPAD=V pads VSN 123 to VVV123. Your JCL specifies VOL=SER=123, the VMF tracks it as VVV123, and displays and reports show VVV123.
CA TLMS manages VSNs in ranges. VSNs in a range have a matching prefix and an incremental numeric suffix. The prefix is the left most part of a VSN which contains alphabetic characters. For example:
