Hi Jon,
If the zpool import command shows the old rpool and associated disk
(c1t1d0s0), then you might able to import it like this:
# zpool import rpool rpool2
Which renames the original pool, rpool, to rpool2, upon import.
If the disk c1t1d0s0 was overwritten in any way then I'm not sure
this operation will work.

I'm new to ZFS and a scenario recently came up that I couldn't figure
out. We are used to using Veritas Volume Mgr so that may affect our
thinking to this approach.
Here it is.
1. ServerA was originally built let's say in January '09 with the
Solaris 10 build from 10/08 with zfs as its default filesystem and was
setup to mirror. So zpool status might show something like this:
pool: rpool
state: ONLINE
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0
0 0
mirror ONLINE 0
0 0
c1t0d0s0 ONLINE 0 0 0
c1t1d0s0 ONLINE 0 0 0
errors: No known data errors
2. Now lets say someone came in and thought that this box was no
longer needed, and reinstalled with the Solaris 10 build from 05/09 with
zfs but didn't mirror it but the root pool is also called rpool. Now
looking like this:
pool: rpool
state: ONLINE
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0
0 0
c1t0d0s0 ONLINE 0 0 0
errors: No known data errors
3. Now the part I can't figure out. It was discovered that there
is data you need from the system before it was rebuilt. How do you get
the data off c1t1d0s0 keeping all your current build, yet pulling off
the old data you need?
I was thinking it might be as simple as doing a zfs import but how do
you do that when your root filesystem is already called rpool?
