The problem with corruption is that mirroring does not fix/prevent this.

Do you have any backups?

What is the extent/symptoms of the corruption?

First check  the /etc/vfstab.
Use the init 0 then enter OpenBoot PROM(ok promt) and then show-disks command.
ok show-devs
ok nvalias backup_root device_path
ok printenv boot_device
ok setenv boot_device disk backup_root
ok boot backup_root
then
/usr/sbin/metastat <disk name ex:d10>
