Bin System (CMS TMCs Only)

You can easily access and manage tapes with duplicate or nonstandard tape numbers by implementing the CA VM:Tape Bin system. The Bin system allows you to define your site’s volsers so they can be referenced by an external bin or slot number instead of the internal volser. By default, the CA VM:Tape Bin system sample user exits assume that all volsers with the first two characters BN are Bin system volumes. You can modify these user exits and change the characters in the volser that indicate Bin system tapes.

Your site may want to implement the CA VM:Tape Bin system for two reasons:

You may have a wide assortment of volsers (for example, TAP001, DECDATA, JOE444 instead of DEV0001, DEV002, DEV003, and so on) that cannot be easily defined using SERIES configuration file records. By using bin numbers to define a series, you can accommodate random internal VOL1 labels in the same library.
You could also use the Bin system if you must handle tapes with identical internal VOL1 labels.

Note: You cannot use either OS Simulation Standard Label Tape Processing Exits (DMSTVI or DMSTVS) with the CA VM:Tape Bin system.

After you have implemented the Bin system, the tape librarian (or a user ID with SAVEFOR, NOMAXRET, and TAPELIBR authorization) can enter tapes into the Bin system. Users can then list and mount bin tapes.
