You can use the fmthard command to mirror disk layouts. Something like this:

Code:
prtvtoc /dev/rdsk/cXtXdXs2 | fmthard -s - /dev/rdsk/cYtYdYs2
And a snapshot is not like a mirror, a mirror is maintained at all times. Any changes in the data are reflected on all disks in the mirror. A snapshot is used to get a point-in-time image of a disk. It will fall out of sync after any updates occur on the actual data.

Well, that depends on what you are working with. Can you provide details like the OS version, the volume manager in use and such?
