System Crash

[Vogra]

3 days old, we had a crash in the system (HP-9000-HP-UX10.20). In the syslog, we have (in the first line) the following:
vmunix: 00640 80080000 00500090 00000000
vmunix: NCR chip register dump:
vmunix: 00: SCNTL3:1b SCNTL2:80 SC
NTL1: 10 SCNTL0:d8
vmunix: 04: GPREG:07 SDID:01 SX
FER: 08 SCID:47
vmunix: 08: SBCL:a3 SSID:81 SO
CL: 01 SFBR:00
vmunix: 0c: SSTAT2:09 SSTAT1:03 SS
TAT0: 01 DSTAT: 00
vmunix: 10: DSA: ffffffce
(...)
Although we know it's a little bit, it's possible to someone help us? Can be something with peripherals disconections? If necessary, we can attache syslog file.
Thanx in advance.

What does the /etc/shutdownlog say?
Was a panic dump saved in /var/adm/crash?

[Vincenzo Restuccia]

Verify SCSI termination.

[Vogra]

Nothing in both of them! I checked SCSI termination after de system up. We stand to believe in problem in it...
Thanx so much.

Ol? Claudio.
Can you post the syslog file? It seems to be HW problem.

[Vogra]

Oi Pedro!
Follow de syslog immediately before de problem. Thanx.

"Zalon Fatal Error" is the tip-off - I believe this is a hardware failure condition.

[Pedro Sousa]

Claudio,
"SCSI: Third party detected bus hang -- lbolt: 29496785, bus: 2"
You had problems with your bus from instance 2.
you can check which bus it is by doing "ioscan -fnkC ext_bus"
then you can check what you have connected to it with "ioscan -fnk"

So, you may have some hw problem/failure on that bus. Check every connections and every thing connected to it.
A good idea is to check it with Diagnostics.
boa sorte.

S? mais uma coisa!
Did you plug /unplug some device before the crash? You should never "play" with scsi buses.

Hello Claudio,

Did the whole system crash? Have you examined the ts99 logfile in /var/tombstones?

If you have a ts99 file but don't know how to read it, you can post it here and we can help.

Good Luck,
Curt

Pedro,
"na mosca" - before the crash, a technician was testing a new tape unit...

Thank you for your help.

Hi Curt,
although the friend Pedro Souza appoint the cause of problem, I would like to know how I can interpret ts99.
Thanx.
