v480 panic and continually reboots

[Sparci]

I am getting the following error in my sun-Fire_V480 which has mirrored
metadevices and "should" be part of a 3.1 cluster. Arrays are 3510s connected via fibre.

Looks like your root file system is corrupted. Also looks like the root file system is mirrored. Have you tried to boot to the root filesystem mirror? If so, I suggest you boot to CD (Software Disk 1) and try fsck and then mount the root partition manually.

bfitzmai,

Tried all that and yes the root disk is mirrored. Tried both disks and no avail. Fsck'd both disk also with no luck.

Any other suggestions?

Try booting to CD and attempt to mount the root partition. I don't understand why you are getting a CPU[Panic]. Even if the file system was corrupted, the CPU should not go into a Panic State. Could it be possible that you have a bad CPU?

well, if the system boots from diagdevices (net, CD, DVD) without panic there should be no HW fault!
I suggest to try to boot a OS from Disk, without mirror:
boot from CD, mount root-FS, edit /a/etc/system -> *-out the whole SDS stuff, edit /a/etc/vfstab #-out all the /dev/md/ stuff and replace it by it's /dev/dsk and /dev/rdsk paths; rename the init Files /a//etc/rcS.d/S35svm.init and /a/etc/rc2.d/S95svm.sync
reboot and press thumbs! ;-)
If your system won't boot something in your root FS is missing or is severely damaged. I suggest to restore System ether from scratch or from backup, depending on what's less time intensive...
