PDC CHASSIS Codes

Kingbee76051 — Fri, 04 Apr 2025 11:56:22 GMT

I am booting an older B132L (HP-UX 10.20) and at random spots during the boot, I am seeing the following message:

PDC CHASSIS: State=FAULT Code=BC00

The boot process never reaches the point where the RC scripts begin to execute. I'm just looking for the meaning of that message. I found an older discussion post from 2001 "Where can I look up PDC codes?", but being that old, the links are broken.

Any help with this would be greatly appreciated.

Thanks,

Brian

Hi Brian,

Being an OLDER workstation , we no longer have any documents available internally.

However, I found an external Service guide available with PDC codes for this workstation.

I looked out for "BC00" , but couldn't find it. You may look for other chassis codes that you see along with "BC00" and see if it helps to isolate the problem.

Thanks.

Hi Brian,

Any luck in isolating the fault using the chassis codes available in the guide?

Let me know.

Thanks

The series of chassis codes starting with B are all pointing to a system panic (crash)..

Determining the reason for the crash will be difficult as HP-UX stops running.

If the system ever gets booted, immediately look in /var/adm/syslog and tail the syslog.log OLDsyslog.log files for more details.
