Summary : Sun Fire 240 keeps rebooting

Thanks every one for help and quick response.
Specially, Jeffrey Seul, mid xinef and Stefan Varga
 
Mirror had problem, so booted the server from cdrom and mounted root file
system,
Changed vfstab to boot from native devices rather than meta device.
deleted meta device files in /etc/lvm, and removed md line from /etc/system
and rebooted.

Server came back ok, then recreated the meta devices and mirrored disks.

The most important part was to remove the /etc/lvm files or removing two LVM
start up
Script to prevent the sync at the start up even when we boot from native
devices.


In my case there was some corrupted files which recovered it from backup
that I had.
For example sd.conf file size was 0 and that was causing problem.

Hi

one of our server keeps rebooting with following error

can not mount root on /pseudo/md@0:0,3,blk
panic[cpu0]/thread=10408000: vfs_mountroot: cannot mount root

=============================================

I have tried "boot -avs" to boot the server on one side of the mirror
but system throw above error right after loading glm1 driver.

I can mount from cdrom with "boot cdrom -s" command and mount root partition
and /var/ but don't know why system can not be booted normally.

any idea ?
