Communicator 3000 MPE/iX Release 6.0 (Platform Software Release C.60.00) (30216-90269)
Chapter 2 35
System Information and Preparation
Special Note on SCSI Device Configuration for MPE/iX 6.0
and MO disk drives. Not adding pseudo devices for an MO device on
MPE/iX 6.0, will cause problems that could lead to the inability to
access data from this device.
Examples:
Pre-MPE/iX 6.0 Configuration
All SCSI devices, except Magneto-Optical devices should have a
"transparent_mgr" configured in systems running MPE/iX versions
prior to MPE/iX 6.0.
This example shows the standard MPE/iX 5.5 SCSI device
configuration, for a C1700A 20GB Magneto-Optical Jukebox. This
library is actually made up of an Autochanger and two disk drives,
resulting in three LDEVs associated with this library. Notice that the
'TRANSPARENT MANAGER' is not used with any of these devices.
Notice also that this happens to be a Precision Bus system.

MPE/iX 6.0 Magneto-Optical Device Configuration
This example is the new/proper configuration for the C1700A 20GB
Magneto-Optical Jukebox on MPE/iX 6.0. This device is made up of the
Autochanger and two disk drives resulting in three LDEVs associated
with this library. Notice that the 'TRANSPARENT MANAGER' must
now be used with both the Autochanger and disk drives. Notice also
that this happens to be a Precision Bus system.
