[indiana-discuss] Cannot Mirror RPOOL, Can't Label Disk to SMI

[Cindy.Swearingen at Sun.COM]

To create a mirrored root pool, you need to use the zpool attach 
command. In addition, you need to specify the slice identifier.
For example:

# zpool attach rpool c1t0d0s0 c1t1d0s0

On an x86 system, you also must have a Solaris fdisk partition.

If you can provide your existing zpool status output, we could
provide more guidance.
