Tru64 installation fails on DS20L

[Steven Guberman]

I have tried NHD7 with the same results as indicated above. The drive
is still not recognized.
The HP specified cable kit for the SCSI drive is CK-DS20L-AA. However,
this kit is no longer available. The drive is connected to a
Symbios riser card and the cable is for 68 pin UltraSCSI3, LVD160.
Can any one tell me the maximum length of the required cable and the
type of termination needed? Many thanks.

Scsi cacble ought to terminator at both ends. That DS20 cable kit might provide that, but I doubt it. Does the cable go straight to the drive or with a mini pcb board in between.
Does the drive have a jumber setting for termination?

Do you happen have a generic cable with terminator slot? One of those 1 1/2 inch wide white flat-cable with a couple of black connector blobs?

SE-scsi can go for some (3) meters, so anything that fits in an DS20L should be fine.

That drive is like an RZ29 right? 4GB, wide, Single Ended.
I believe that the Symbios (LSI) 53C100 with auto-detect LVD versus SE... with the right cable.

>> PCI device at bus 0, slot 3, function 0 could not be configured.
And the Console reports the drive to be in that slot. Nasty.

Now the console also seems to report 2 CD-roms. Is that correct? How about keeping dqb for the CD and try using an IDE system disk as DQA, at least to try and maybe for keeps? It will easily be bigger than 4gb :-).

Thanks, Hein, for your message.

From the NHD-6 Release Notes:

2.1.9.1 DS20L or DS25 Boot Messages
During a DS20L or DS25 system boot, you may see the following PCI table
error message:
PCI device at bus 0, slot 3, function 0 could not be configured:
Vendor ID 0x1000, Device ID 0x21, Base class 0x1, Sub class 0x0
Sub-VID 0x14d9
Sub-DID 0x8002
has no matching entry in the PCI option table
You also may see the following unrelated driver error message:
< fatal="" error="">
fd internal driver error: FDI PROBE FAIL (A,11).
Both of these messages reflect known errors and can be ignored.

Yes, that's the configuration. I'm using a 40" Amphenol cable, AWM 80C LL31941 CSA with 68 pins and active termination. Shouldn't this work? According to SCSI specifications, the cable is not too long and the bus should run in single ended mode with that disk drive.
I will probably try the IDE drive although I don't expect it to work in Tru64.

The last sentence in my prior message was:
" I will probably try the IDE drive although I don't expect it to work in Tru64." My expectations were proven wrong upon hooking up an old IDE drive to one of the two IDE connectors on the mother board. It works! I was able to set up a bootable ide drive with Tru64 installed. Thanks Hein for the suggestion--I owe you some points.

Separately, I am having some trouble with licenses but I will start a separate thread for this.

Excellent. That's _so_ much more convenient to use as a base to figure out what is wrong with the SCSI, or you could even just leave it as OS disk.

It worked for me on a DS10, so I had good hope.

Cheers,
Hein.
