Cartridge entry installation exit (CBRUXENT) return codes

The following are the return codes that can be passed back from the exit:

Code: Meaning
0: Perform cartridge entry as requested. No changes have been made to the parameter list (CBRUXEPL). Use what existed at the time the installation exit was called.
4: Perform cartridge entry and note that one or more fields in the parameter list (CBRUXEPL) have changed.
8: Do not allow this cartridge to be entered. For an automated tape library dataserver, OAM schedules the cartridge to be ejected.
12: Ignore the cartridge entry request. For an automated tape library dataserver, OAM leaves the cartridge in the library (volume left in the insert category).
16: Do not call the cartridge entry installation exit again. Perform cartridge entry as requested using the attributes that existed at the time that the exit was originally called.

If an invalid return code is passed back, OAM discontinues cartridge entry processing.

Note: Once OAM is told not to invoke the installation exit again (return code 16) or cartridge entry processing is discontinued, the only way to reactivate the exit is to stop and restart OAM, or to issue the LIBRARY RESET,CBRUXENT command.
