BRMS can support some third party (non-IBM) media libraries. To add third-party media libraries to BRMS, take the following steps:
myCommand dev(&DEVICE) vol(&VOLUME) mlb(&MLBNAME)
Customers or manufacturers can use the following variables with each of the MLB commands. The tape exit supplies the values for these variables.
BRMS supplies the following messages for users of third-party media libraries. You can find them in message file Q1AMSGF in library QBRM.
If BRMS issues these messages as escape messages, then BRMS retries (BRM1990) or fails (BRM1991) the job as appropriate. Use the Work with Registration Information (WRKREGINF) command to add and register a program to an exit point.
