Here is a poor man's failover scheme.
Copy primary boot disk to second disk. If primary boot disk fails, reboot to the secondary's disk instead of rebuilding the OS.
- umount secondary disk's partition
- newfs the filesystems
- remount the partition
- perform disk to disk copy
- copy prepared /etc/vfstab2 to secondary disk's /etc/vfstab
- issue installboot command

...and so on and so on for remaining partitions
