kernel logging causes a system crash?

Daniel Gowans — Tue, 25 Mar 2003 18:38:53 GMT

On a C3000 running HPUX 11.11

In SAM I enabled Kernel logging to help me figure out a problem that was going on. A subsequent reboot, and the system crashed.

A. Is there a way to use the IPL to see what all the information is that it prints to the screen when it crashes, or another way to capture that information?

B. I unplugged a SCSI drive while the system was turned off and plugged it back in. Now of course this shouldn't do anything, but systems can be tempermental.

C. Is there a way to get in and turn off kernel logging by booting from CD or something, to make sure it wasn't something else?

Did the system dump? If so it needs to bve read to determine what happened.

If it crashed, the dump will be in /var/adm/crash.

Well, it was much simpler than that. It had nothing to do with kernel logging. I looked at the crash files and one of the hardware devices (a second SCSI drive) wasn't showing up. I took it out, cleaned the contacts, checked the cables, put it back, and now everything is fine.

Thanks!
