A mount for a tape volume is about to be requested on unitaddr. The type of tape volume specified in this message indicates the appropriate type of cartridge to be mounted. If the message indicates that the required media type is STANDARD CAPACITY, the operator should mount a tape volume of standard capacity. If the message indicates that the required media type is ENHANCED CAPACITY, the operator should mount a tape volume of enhanced capacity. If the message indicates a MEDIAn cartridge, where n is a number, then MEDIAn identifies the type of media needed. After a tape volume of the requested type is mounted, reply ‘Y’ to the outstanding message to allow processing to continue. If the requested type of tape volume cannot be mounted, also reply ‘Y’ to continue. In this case, the particular TAPECOPY of that volume fails, but the TAPECOPY command continues with the next volume copied. Any reply other than ‘Y’ causes the TAPECOPY not to continue, and the TAPECOPY waits until a reply of ‘Y’ is entered.
DFSMShsm processing for that task waits for the tape mount requested by OPEN to be satisfied, and the operator replies to the outstanding message before continuing. All other DFSMShsm processing continues.
This message is issued only if requested by a patch of the MCVT + 4C3 BITS(.......1). Otherwise, ARC0332A is issued for the TAPEOUTPUTPROMPT processing.
