Restoring a Root File System that was on a metadevice

Hello I use Solaris 10. I need to restore the root file system, but I don't know how . i can only boot the server in safe mode or with the cd (ok boot cdrom -s)

Do you guys know a good procedure, I don't want to break the mirrors.

( the server is not a cluster).


Its an emergency, i would appreciate a quick help

WARNING: The following files in / differ from the boot archive:


The recommended action is to reboot to the failsafe archive to correct
the above inconsistency. To accomplish this, on a GRUB-based platform,
reboot and select the "Solaris failsafe" option from the boot menu.
On an OBP-based platform, reboot then type "boot -F failsafe". Then
follow the prompts to update the boot archive. Alternately, to continue
booting at your own risk, you may clear the service by running:
"svcadm clear system/boot-archive"

You have to rebuild the boot archive first. After logging into single user mode, run this:
Code:
bootadm update-archive -f

Then clear the service state and reboot the system.

# OK boot failsafe -F
#bootadm update-archive -f
# svcadm clear system/boot-archive
