28696 SCSI Card

[BONNAFOUS Jean Marc]

Sorry if my english isn't good: I am french.

I want to add a 28696A F/W SCSI Card on a G50 (HP-UX 10.20). When I add scsi3 driver in kernel the server don't boot. It stop at :

:disc(52.4.0 /stand/vmunix
3783660 + 327680 + 475392 start 0x15b0e8

I must to cut power and remove the SCSI card. Then the server boot again.

Please can you take me a solution ? Thanks.

What chassis code does the consloe show when the system hangs (Ctrl-b in the bottom line) I bet CEF2, right?
At this point tries the kernel to initiate the IO tree. If there are some IO problem it does not compete this task and panics after a while. Did you connect anything to the 28696A? If yes, try to disconnect the whole SCSI bus and terminate the Interface. Or didn't you connect anything to the SCSI host bus adapter? in that case you need to check the selftest LED of the interface and the term power. Did you terminate the interface? Remember, you need to terminate both ends of a SCSI bus, even when it's just a few cm long.

The chassis code is CEF2.
I have test with and without disk connect to the interface: the problem is the same in the two cases.
The power led is on, the "selftest fail" led is off. The led on the terminator is on but the system don't boot (and don't panic).

It sounds like you may have a faulty adapter, do you have another one to test?
Also, try rebooting from the previous kernel, prior to adding the driver, and see what happens.

[Patrick Wessel]

What kind of Terminator do you use? Terminators with an LED mounted are usually Ultra/SE terminators.

(The system will panic if you give it enough time)

Aside from the scsi3 driver you may also need the disk3 driver in the kernal.

I had a same problem.
I solved it by replacing the card.
I know new f/w for 28696 card was released. But I don't think the old f/w is a problem.
I think replacing is the best.
