Panic Reboot without any record in shutdownlog

[Leonard C.]

Dear All,
We are using Oralce RAC10g on HP Integrity servers (HP-UX 11.23)
Sometimes Oracle CRS reboot the server in panic mode.

syslog before reboot :
Jul 29 17:04:07 servername syslog: Oracle CSSD failure 134.
Jul 29 17:04:07 servername syslog: Oracle CRS failure. Rebooting for cluster integrity.
Jul 29 17:04:12 servername syslog: Oracle clsomon failed with fatal status 12.

After rebooting there is no log in /etc/shutdownlog

But sometimes after Panic Reboots, shutdownlog is also indicating the reboot.

Actually we can not always refer to shutdownlog file to check the reboots.

Any idea?

Well if Oracle is rebnooting the box, it has been known to call reboot with a -q (or quiet) option. This reboots the server without leaving an entry in the shutdown log.
You should check with Oracle regarding this.

Shalom,

This is the equivalent of a serviceguard TOC.

Oracle is doing it. Oracle is responsible to log the cause.

Some criteria of the cluster configuration is leading Oracle to believe a split brain problem is coming up and that risks data corruption. So the node gets booted.
