The drives are in Coraid  connected to the server via Coraid 10G HBA card.
Its exported and imported on the same host but after OS upgrade ( format OS
disk and install again ). Before OS upgrade, zpool export was issued and
when tried to import it faults as below. The pool is not functional in any
system now.  Tried -d /dev/dsk option but no luck.


root at storage1:~# zpool import
   pool: pool1
     id: 10136140719439709374
  state: FAULTED
 status: The pool was last accessed by another system.
 action: The pool cannot be imported due to damaged devices or data.
        The pool may be active on another system, but can be imported using
        the '-f' flag.

       Destroy and re-create the pool from
       a backup source.
