I need to install a magneto-optical 3.5" external SCSI unit
to a DIGITAL workstation ALPHA 500/500 (Digital UNIX 4.0B).
The unit has been connected to the workstation and has been recognized
at hardware level.
The ALPHA workstation recognizes it as "optical" (not "rz?")
at the selected SCSI address

After the execution of command:
/dev/MAKEDEV rz5
(for SCSI address 5), it is not possible to execute the disklabel
command on such a special device file.

Please, could anyone help me in installing this non-DIGITAL device ?

Thanking you ,
