ok, Let me explian our problem.
Actually we have 11 disks inside the server
1) using 10 disks we have a created zfs pool using raid 1+0 config.
2) one disk was used for Operating system
3) we are using solaris 10 upate 5
4) suddenly one of the disk inside pool got faulty and also for os file
system we are getting fsck error.
5) we have replaced the disk inside the pool
6 Also we have reinstalled the server using same solaris update 5.
7) once installation completed we are unable to import the pool
8) getting following error
zfs import poolname, .
pool: mypool
id: 7930692275762395656
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.

9) if i tried zpool import -f pool, the server is getting rebooted,
I can see following error in /var/adm/messages.

That's great.
As I said previously, if you included the stack trace from the messages
file, we could have a guess at what bug/problem you're seeing. It will
be the line which starts:
panic[cpuX]/thread=xxxxxxxxxxxxx:
and continues until you see "syncing filesystems..."
Also, as this is Solaris 10, you should be logging a support call and
making use of your support contract. Your kernel patch indicates you are
running around Solaris 10 update 7. Since then, there has been Update 8,
Update 9, and patches from the Update 10 development branch. It may be
that you are hitting a known bug, but I would strongly recommend that
you talk to one of our support personnel as they will take a more
detailed look at your system as a whole and guide you through the
required procedure, rather than me blindly recommending patches.
Regards,
Brian
