Re: HP DAT72 and disks on same bus on a PWS
Which Qlogic card are you using specifically ?
> but once booted the tape was missing.
By missing do you mean the /dev/tz* device wasn't present ? (I'm assuming you're using 4.0x). Is it the case that you just need to create the device files with MAKEDEV ?
What does the output of "scu show edt" show you ?
Cheers,
Rob

Re: HP DAT72 and disks on same bus on a PWS
This is the situation:
I have now confirmed that the tape and at least two disks can work together on the internal scsi bus provided that "Force Single-Ended mode" is enabled on all disks, using tru64 V4.0F.
I have now
dkc0
dkc100
mkc500
and nothing connected to my LSI Logic KZPCA-AX interface for the moment. My QLogic KZPBR-CY did not work, so I put it aside.
After booting a pre-installed V5.1B-4 disk (installed without the tape or tape connected to a different scsi configuration) I am not able to get the tape into the system. genvmunix/doconfig is NOT doing the trick. Someone suggested it is necessary to REINSTALL V5.1B to detect and get new hardware support. Is this really true?
./MAKEDEV tz21 did not produce any working nrmt0h device. # file /dev/nrmt0h claims scsi id#0 which is not true.
Should some other tool be used in V5.1B to install new hardware?
For now, my prime target is to vdump my 5.1B-4 disk on tape, since I put a lot of work in the configuration of some external hardware support, and I need this physical disk to replace a failing 4.0F system disk on another "production" machine.
I tried to do the vdump operation from the 4.0F disk, but strangely enough, I can mount the /usr/users file system on the V5.1B-4 disk but not / or /usr, Mount claims they do not contain a valid AdvFS file system, while disklabel -l says it does.
So I guess I have to boot on the 5.1B-4 disk to do the vdump, but now I have no tape support in it.

Re: HP DAT72 and disks on same bus on a PWS
# hwmgr -scan scsi
The "mt" command is now working, and also "vdump".
Question:
Which device file is now connected to my tape, if any?
If I do "# file /dev/*mt*" the info I get points to SCSI ID #0, which is wrong, should be 5. The same for /dev/tape and /dev/ntape.
So I am confused.
Any comments?

> it aside.
If that was actually a KZPBA-CB/CY (lots of
plug-in terminator resistor packs), then I'd
expect it to be a differential SCSI card
("HVD", in modern lingo), so I wouldn't
expect it to work with LVD/SE devices. (I
was once (2002) the only bidder ($8) on Ebay
for a "K2BPR-CX" card. Apparently, no one
else noticed that it was really a KZPBA-CX,
being offered by a seller who read it
wrong.)

Tell that person to stand on one leg and
scream like a chicken, and then try:
dn_setup -boot
See, for example:

What makes you think that any "0" there is
related to SCSI ID 0? (Is it true for the
disks in "/dev/disk"?)

Ok, I see now that I did not realize the change in device files between 4.0F and 5.1B. "# file /dev/...." does not show the same info as in 4.0F, if any useful at all.
So I will RTFM and study hwmgr instead.
I think all is covered now.
I learnt (by myself actually) not to mix LVD/SE and LVD devices on the same bus;
I learnt not to assume ANY similarities between device management in 4.0F and 5.1B;
Thanks a lot!

Device management was one of the major changes between 4.0x and 5.x.
Glad to hear that you figured it out.
Remember to say thanks by assigning points.
Cheers,
Rob
