[comp.unix.ultrix] Sony Optical on DS3100

hhd0@GTE.COM (Horace Dediu) (09/20/90)

I'm still trying to set up a Sony Read/Write SCSI Optical Drive on a DS3100.
It's set up as unit 3 along with an RZ55 and a TK50 on the SCSI bus.
The hardware is visible to the console monitor and I did a 
	>>scsi fm 3
which worked.  The drive passed the DEC extended mode self test, but failed the 
	>>scsi cd 3
(Read/write test for SCSI hard drive) with 
"illegal data out length specified"
and 
"Drive write error***".
The drive can be set up and it returns inquiry respones and a ready status.

The problem is when using rzdisk.  I issued
	#/bin/rzdisk -f /dev/rrz3c
and the system just went away hung (^C did nothing).  It came back only after 
turning the power to the drive off.  Any other rzdisk options have the same 
effect.  I am running Ultrix 4.0.  I had similar problems with earlier versions
of Ultrix, and thought that 4.0 would solve them.  What can I do?
