my original question:
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
# uerf

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 ?

"Optical" is a distinct SCSI device type from "Direct access"
"Optical" is a distinct SCSI device type from "Direct access"
(disks). The disk driver on Digital UNIX only supports Direct
access devices. Many optical devices have a switch or firmware
option that allows them to become direct access device. Check
your documentation to see if this device is one of those and
switch it if possible. If you'll have to find a way to get the
optical driver from the CAM Layered Components kit.
The drivers in the CLC kits are licensed software, but not sold
independently. I think OSMS, OSDS, Networker and the old HSM
product, are the only ones that license the optical driver.
