The OAM CBRUXENT exit is executed whenever a tape cartridge is inserted into the ATL. The CBRUXENT exit, which is provided by CA 1 determines the status of the tape within the TMC, then allows or disallows the entry of the tape and sets the status in the TCDB to scratch or private based on the status in the TMC. When installed, the CBRUXENT exit updates TMC fields ROBTY and ROBID to indicate the tape is in the ATL. By default, a foreign tape may not be entered into the ATL. If this is attempted, the tape is left in insert status. This exit must be customized to specify the SMS name of each robot in an internal table for both IBM ATL and IBM VTS implementations.
The CBRUXENT exit calls the module CTSQSTS, to get the status of the TMC volume being entered into the IBM ATL or VTS.
CTSQ returns the following codes:
Tape is in scratch status.
Tape is non-scratch and can be appended.
Tape is full (part of a multivolume chain) or owned by an EDM or CA Dynam/T.
Tape is marked BAD by CA-9/R+ or tape is in delete status and thus out of service.
Tape is not in the TMC (foreign tape).
There was an error trying to obtain the status of the tape.
