zfs discuss - Jan 2009 - I/O error when import

I have a 3 disk raidz configuration, one disk reports lots of error so I decided
to replace it.
At the same time I replaced the system disk and reinstalled the system(the same
version).
When I try to import mypool, I got an I/O error.
What could I do to import it, replace the new disk(c2d0) with the original disk
used in raidz and try again?

bash-3.2# zpool import -f     
  pool: mypool
    id: 4052179541023957932
 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.

config:

	mypool      FAULTED  corrupted data
	  raidz1    DEGRADED

I wonder if your problem is related to mine:
(can''t import zpool after upgrade to solaris 10u6 -
http://www.opensolaris.org/jive/thread.jspa?messageID=324994#324994).

What does zdb -l give you?

zdb -l /dev/dsk/c1d1
zdb -l /dev/dsk/c2d0
zdb -l /dev/dsk/c2d1
