4.Run the SYSGEN utility, IO subsystem:

:SYSGEN

SYSGEN>IO

For a SCSI tape library (DLT) device, add:•The path and device for autochanger:

IO>PATH PATH=56/52.0 ID=PSEUDO

IO>ADEV LDEV=30 PATH=56/52.0.0 ID=PICKER

•Paths and devices for tapes:

IO>APATH PATH=56/52.2 ID=PSEUDO

IO>ADEV LDEV=31 PATH=56/52.2.0 ID=DLT8000

MODE=AUTOREPLY

IO>APATH PATH=56/52.3 ID=PSEUDO

IO>ADEV LDEV=32 PATH=56/52.3.0 ID=DLT8000

MODE=AUTOREPLY

The MAPPER utility lists the path number (for example, PATH=56/52.0) and the device ID (use the first word from Component Name, for example ID=DLT8000).

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.

5.For path number (PATH=56/52.0-PATH=56/52.0.0) from MAPPER utility, for ID use the first word from Component Name (ID=DLT8000), for autochanger use PICKER (ID=PICKER) and for LDEV numbers use any free number from 1-255.

NOTE:

For SCSI devices, use PSEUDO as the device identifier.
