I have a MicroVAX-II and I want to add a Kennedy 9600 9 track drive.
AFAIK, this drive has a standard Pertec interface and I was planning to use
it with a Dilog DQ132 controller. The drive is capable of both 800 and
1600bpi, and I need to be able to use it at both densities.
I installed it and cabled it all up - VMS (v4.5 in this case) sees the
DQ132 and autoconfigures it as MSA0 (a good sign!), and the drive seems
happy and loads a tape. VMS reports that MSA0 is a TSV05 (which is what I'd
expect) and doesn't log any errors. But, whenever I try to access the
drive, VMS says that it's offline and I can't get it to actually do
anything.
Yes, the Kennedy is actually online (the online LED is lit) and the
"select" LED on the drive flickers for an instant when VMS tries to access
the drive. The drive is set as unit 0, and it was working the last time it
was used (with an Emulex controller in that instance).
Just for fun, I tried the Kennedy drive with a real TSV05 (M7196)
controller that's known to work with a real TSV05 drive - same results.
Is there any obvious reason why this wouldn't work?
The 9600 is Pertec, right? If you Google for this drive you'll find a
couple of places that say it's SCSI, but that seems wrong.
Anybody got a manual for the 9600? Bitsavers has the manual for the 9610,
but it appears that the 9600 is substantially different.
No manual but do check the interrupt grant chain. I've been dinged a few
times because I had a gap in the chain and VMS sorta finds the device
but cant really work it.
