How to export zpool from alternate disk slice?

by

I need some help in recovering ZFS pool. Here is scenerio. There are two disks –
c0t0d0 – This is good disk. I cloned it from other server and boot server from this disk.
c0t1d0 – This is original disk of this server, having errors. I am able to mount it on /mnt. So that I can copy required data from this to c0t0d0

Below pool is not imported yet and copy of another server, from where I have cloned

# zpool import
  pool: zplctpool
    id: 11623878967666942759
 state: DEGRADED
status: The pool was last accessed by another system.
action: The pool can be imported despite missing or damaged devices.  The
        fault tolerance of the pool may be compromised if imported.
   see: http://www.sun.com/msg/ZFS-8000-EY
config:

        zplctpool          DEGRADED
          mirror      DEGRADED
            c0t0d0s7  FAULTED  corrupted data
            c0t0d0s7  ONLINE

I do not want this zplctpool, it can be deleted. Instead, I want zplctpool, which is sitting on c0t1d0s7

Regards

Not sure I completely follow what you’re trying to accomplish, but the end goal seems to be to move a zpool from one system to another.

The first warning is that you probably didn’t issue a zpool export on the drive from the other system.

I’m perplexed that your pool is listing a mirror across c0t0d0s7 and itself (c0t0d0s7). When you say you cloned a drive, did you mirror? To do that, you need to split the mirror to make both drives usable–which I think is a new feature in Solaris 11.
