C180 crashes and reboots suddenly

[Jeroen_D]

Hi,

we have a C180 that has crashed twice yesterday and again today.
I have checked the syslog and OLDsyslog file and typed dmesg but there does not seem to be anything wrong.
I thought I would find some SCSI bus reset error but no.

In the /var/adm/crash I found an index file in a core.0 directory :

comment savecore core dump INDEX file

Does anyone know what this means ?
Thanks in advance. I think that a software crash should not reboot a machine but maybe I am wrong ?

Best regards,
Jeroen.

This panic is usually caused by I/O errors while reading from a paging area. Try to read from your swapdevices. Maybe you are able to isolate the problem this way, e.g.:

dd if=/dev/vg00/rlvol2 of=/dev/null bs=256k
dd if=/dev/rdsk/c0t6d0 of=/dev/null bs=256k

Be prepared to replace the disk.

Best regards...

panic reactivate: cannot bring in U area
This indicates the probability of a failing disc area, where you have assigned swap space.
What does your /etc/shutdownlog show for hte last few entries?

What are you asssinging for swap, i.e. what is in your /etc/fstab, other han primary swap?

Hi,

in the /etc/shutdownlog :

shutdownlog :
10:01 Mon Jan 20 2003. Reboot after panic: reactivate: cannot bring in U area
17:02 Wed Jan 22 2003. Reboot after panic: reactivate: cannot bring in U area
17:08 Tue Jan 28 2003. Reboot after panic: vfdswapi: syncpageio detected an error
13:56 Wed Jan 29 2003. Reboot after panic: vfdswapo: syncpageio detected error
10:58 Thu Jan 30 2003. Reboot after panic: reactivate: cannot bring in U area
12:40 Thu Jan 30 2003. Reboot after panic: vfdswapo: syncpageio detected error


=> I'll call HP support to check the warranty and support contract on this C180 station. Guess this puppy has had it.

Thanks for the help !

Regards,
Jeroen.

Yes, looks like you need a new disk
