Question

do
    for server in server1 server2
    do
        somestr="Some String"
        echo "$server hdiskpower$i \c" ; ssh $server "lsattr -El hdiskpower$i |grep $somestr "
    done
done

Answer 1

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"
