I think this is what you need: At first you need to install sshpass on your machine. then you can write your own script:

while read pass port user ip; do
sshpass -p$pass ssh -p $port $user@$ip <<ENDSSH1
    COMMAND 1
    .
    .
    .
    COMMAND n
ENDSSH1
done <<____HERE
    PASS    PORT    USER    IP
      .      .       .       .
      .      .       .       .
      .      .       .       .
    PASS    PORT    USER    IP    
____HERE

If you are passing some variable to remote server inside a command, then those variable must be defined at that remote server.

Like, if you hardcoded the command in script like "echo "$server hdiskpower$i \c" ; ssh $server lsattr -El hdiskpower71 |grep XYZ" then it surely works for you.

Meanwhile i will work to make it workable with variables.

You must use -t parameter to set ssh to use pseudo-tty. If you'd like to run that command on a remote machine, you'd do it by

ssh $server -t "lsattr -El hdiskpower$i|grep $somestr"
