Is the UC07 supported by 2.11BSD? I know that
when I considered
installing it on my PDP-11/73 that it had issues with my Viking QDT
SCSI Adapter.
http://minnie.tuhs.org/PUPS/Setup/2.11bsd_setup.html
"MSCP disks and TMSCP tapes include SCSI drives attached to the RQZX1
controller on the PDP-11/93. MSCP disks and TMSCP tapes also include
SCSI drives attached to the Emulex UC07 or UC08 Q-BUS controllers on
Q-bus systems as well as the UC17 and UC18 controllers on UNIBUS systems."
But, I'm starting to think maybe the boostrap is more restrictive.
As far as tape issues, I use a DEC TLZ06 4mm DAT
on my PDP-11/73, as
well as a TK50. I was able to install RSTS/E from 4mm without any
problem, but couldn't install layered products from 4mm, for those I
had to use TK50's. I don't know if there could be any strange
issues like that or not. A DLT8000 drive is quite a bit different
from a TK50.
I'll check with a couple people I know, and see if they have any
idea. I am wondering if you can even boot from a DLT8000 drive.
BTW, is the drive HVD, or something else? I believe that all of the
DLT8000 drives we had were HVD.
My DLT8000 is LVD, and will run SE.
When connected to the pdp11/53, the "SE" LED lights on the terminator
plugged into the drive, The UC07 is also correctly identifying:
"Drive #1 is Online , QUANTUM , DLT8000"
The UC07 is successfully able to perform it's F.R.D. tape read and write tests.
When connected to the Sun, the drive operates in LVD mode, and tapes can be
written and read fine. I don't have a HVD controller in the Sun.
