5. For a standalone (DDS) device, add:
• Path for device and identify it as PSEUDO:
• Tape drive device (always on path address ending with 0), set ID and mode
as AUTOREPLY:
IO>ADEV LDEV=30 PATH=52.3.0 ID=HPC1533A MODE=AUTOREPLY
• Autochanger (robotics) device and identify it as PICKER:
IO>ADEV LDEV=31 PATH=52.3.1 ID=PICKER
The MAPPER utility lists the path number (for example, PATH=52.3) and ID for
the device (use the first word from Component Name, for example
ID=HPC1533A).
The LDEV number is any free number from 1-255. You can check already used
numbers by listing all devices with SYSGEN, IO subsystem, or the showdev
command:
:SYSGEN
SYSGEN>IO
IO>LDEV
:SHOWDEV
The path address for autochanger is usually the path address for tape +1.
NOTE:
For SCSI devices, use PSEUDO as the device identifier.
