9.1.7.2 Emulated tape devices from the BS2000 viewpoint
Instead of the EMFILEs and CDROM files, BS2000 sees tape devices of the type
BM1662FS which are addressed by means of their mnemonics. In the drives tapes of the
type T6250 (T9G) are visible which are addressed using their VSNs and are handled in the
same way.
EMFILEs
The following BS2000 commands are relevant for tape drives which are emulated by
EMFILEs:
ATTACH-DEVICE
Attaches a tape device; mandatory before use.
DETACH-DEVICE
Detaches a tape device. The actions uploading, downloading, deletion of the data, and
removal of the emulated device via the SE Manager only make sense in the “detached”
status.
INIT utility routine
Initialization of a tape using the INIT utility routine; mandatory if a new EMFILE
emulates a tape. For details, see the "Utility Routines" manual [11]. Specify “T9G” as
the volume type and define the VSN.
CDROM files
The following BS2000 commands are relevant for tape devices which are emulated by
CDROM files:
ATTACH-DEVICE
Attaches a tape device; mandatory before use. Even if the CD or DVD drive is empty,
the corresponding tape device can be attached in BS2000. When you have inserted a
CD/DVD later, enter the CHECK-TAPE command to make the mounted volume known
to BS2000.
CHECK-TAPE
Makes a mounted volume (CD/DVD) in the emulated tape drive known to BS2000. The
CHECK-TAPE command is needed if the drive was still empty when a previous
ATTACH-DEVICE command was issued or the CD/DVD was changed after UNLOAD-
TAPE.
