zfs discuss - Jan 2009 - ZFS import on pool with same name?

I have an OpenSolaris snv_101 box with ZFS on it. (Sun Ultra 20 M2)
zpool name is rpool.  The

I have a 2nd hard drive in the box that I am trying to recover the ZFS 
data from (long story but that HD became unbootable after installing IPS 
on the machine)

Both drives have a pool named "rpool", so I can''t import the
rpool from
the 2nd drive.

root at hyperion:~# zpool status
   pool: rpool
  state: ONLINE
  scrub: none requested
config:

         NAME        STATE     READ WRITE CKSUM
         rpool       ONLINE       0     0     0
           c2t0d0s0  ONLINE       0     0     0

errors: No known data errors

root at hyperion:~# zpool import
   pool: rpool
     id: 6530745808930953819
  state: ONLINE
action: The pool can be imported using its name or numeric identifier.
config:

         rpool       ONLINE
           c2t1d0s0  ONLINE

If I run ''zpool import rpool'' I get "cannot import
''rpool'': pool already
exists" (which makes sense)

How can I import the rpool from the 2nd hard drive and have it mount on 
a different partition or something so I can recover the data from it?

Thanks,
Josh

You rename it as you import it, eg:

zpool import 6530745808930953819 newname

Cheers,

I was able to do  ''zfs import rpool monkey'' but then I
can''t seem to
mount the data anywhere to get the data off.

I imported it, then did ''zfs set mountpoint=/monkey monkey''
and did a
''zfs mount monkey'' but I don''t see anything from
/export/zones, etc.

I''m sure there''s a simple workaround for this and that
I''m just missing
the obvious here....

Thanks.

root at somemachine:~# zpool
missing command
usage: zpool command args ...
where ''command'' is one of the following:

...

        import [-d dir] [-D]
        import [-o mntopts] [-o property=value] ...
            [-d dir | -c cachefile] [-D] [-f] [-R root] -a
        import [-o mntopts] [-o property=value] ...
            [-d dir | -c cachefile] [-D] [-f] [-R root] <pool | id>
[newpool]

give a new name at newpool..
