The OAM CBRUXENT exit is executed whenever a tape cartridge is inserted into the ATL, or when a virtual volume is imported from a physical tape or defined to the VTS. The CBRUXENT exit provided by CA 1 determines the status of the tape within the TMC. CRBRUXENT 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 provided with CA 1 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 ATL and VTS implementations.
