Hi Sudheer,

As suggested by Christian, check if zpool clear brings the pool online. There was a bug which recently got fixed, which will take care of this problem. Your
    Solaris version is on the lower side.

Thanks,
Deepak.

1)The FC Luns are available after reboot.
ok, you are using FC Luns and do not enable MPXIO?
2) The Os level of the machine : Oracle Solaris 10 8/11
s10x_u10wos_17b X86.


3)bash-3.2# zpool status
   pool: pool name
  state: UNAVAIL
status: One or more devices could not be opened.  There are insufficient
         replicas for the pool to continue functioning.
action: Attach the missing device and online it using 'zpool online'.
    see: http://www.sun.com/msg/ZFS-8000-3C
  scan: none requested
config:NAME        STATE     READ WRITE CKSUM
         pool name      UNAVAIL      0     0     0  insufficient replicas
           c5t1d1    UNAVAIL      0     0     0  cannot open


4) at the time of reboot the machine itself imports the zpool&  no
need to import it again.
bash-3.2# zpool import pool name
cannot import 'pool name': a pool with that name is already
created/imported,
and no additional pools with that name were found.


And the important thing is when I export&  import the zpool, then I
was able to access it.
As Gary and Bob mentioned, I saw this Issue with ISCSI Devices.
Instead of export / import is a zpool clear also working?

mpathadm list LU
mpathadm show LU /dev/rdsk/c5t1d1s2
