If you need to work on vi,just export your EDITOR and TERMINAL
just check for ZFS file systems mounted
2) #export EDITOR=vi
export TERM=vt100
# zfs list
no datasets available
--------------------------------------------------------------------------------
as there are no pools we have to import pools and
this will tell what all pools are there to import
3)# zpool import
pool: zpool
id: 12781544736217994069
state: ONLINE
action: The pool can be imported using its name or numeric identifier.
config:
zpool ONLINE
c1t0d0s0 ONLINE
--------------------------------------------------------------------------------
import the pool required and it will display the following message.
These ZFS file systems doesn't get mounted but still it exists
4)# zpool import zpool
cannot mount '/export': failed to create mountpoint
cannot mount '/export/home': failed to create mountpoint
cannot mount '/zpool': failed to create mountpoint
--------------------------------------------------------------------------------
now check for the ZFS filesystems mounted,we can notice that the /etc/shadow file
that we need to access is in zpool/ROOT/s10s_u9wos_14a which is mounted on / is in use

(its difficult for vi rditor to work in some systems..in that case please make use of other unix commands to make changes to the file.For me also this didn't work.what i did was using vi commands like-w,cw,dw-i made changes)

if you want to check again,got to /etc/shadow and again delete the entry in
encrypted shadow region(What i did was i took the encypted shadow part from a server for which i knew the root password and pasted here)
---------------------------------------------------------------------------------
10)init 6
now u can login to the server without a password if you have deleted the entry in /etc/shadow or with the password of the server from which you have taken the encrypted field /etc/shadow
