No.  There should be a class called SCSI PASSTHRU or some such.  It's not a
pseudo device, it's a SCSI passthrough driver than sends the scsi commands
to the device unaltered.

What rev of MPE are you on?

It's been well over a decade, so bear with me.

The ldev for the SCSI address of the tape unit is configured as a standard
DDS or DLT.  The robot is configured as a scsi-passthru device.  You will
need software to drive the robot, unless you configure it in semi-automatic
mode.  

What auto-changer are we talking about here?

Does anyone remember how to configure an HP auto-changer tape unit on the
HP3000?  It has two scsi addresses.  One for the tape unit, the other for
the changer itself.
