It appears that an application (Courseinfo/mysql) is causing the panic

reboots and there's nothing wrong with mirroring or the hardware. We

haven't actually confirmed this yet . . .

But, our backup script was shutting down Courseinfo and then restarting it

after the dump was complete. We found errors in the startup scripts for

Courseinfo that we think are the problems. I've taken the Courseinfo stop

and start entries out of the backup script and we'll see what happens

tonight.

As far as the message:

"Apr 13 04:27:11 courses syslog: /usr/sbin/pmconfig: /etc/power.conf line

(31) failed to convert mount point /dev/md/dsk/d3 to prom name"

the cause is:

"pmconfig for autoshutdown needs to write state information to a partition.

that partition must be available at the prom level. if you have a mirrored

configuration, the prom cannot save to a metadevice. if your system does

not

use autoshutdown, you can ignore the message or remove the Power Management

packages."

An additional note about mirroring and DiskSuite. savecore was failing as

dumpadm must be reconfigured after switching to metadevices.

/etc/dumpadm.conf was using /dev/dsk/c0t0d0s1. I used the command:

"#>dumpadm -c all -d /dev/md/dsk/d2 -m 5%" to reconfigure"

If I get a panic reboot tonight we'll find out if that works.
