custom script to turn on / off of nodes for bigip v11

A little different, but I think this should work:

!/bin/sh

prog="nodemgmt"

enable() {
    change_status "user-enabled" "user-up"
}

disable() {
    change_status "user-disabled" "user-down"
}

status() {
    show_status
}

show_status () {
    while read line
    do
        a=( $line )
        p=${a[0]}
        m=${a[1]}
        tmsh show ltm pool $p members {$m}
    done < $data
}

change_status() {
    while read line
    do
        a=( $line )
        p=${a[0]}
        m=${a[1]}
        tmsh modify ltm pool $p members modify { $m { session $1 state $2 } }
        echo "$1 pool $p, member $m $2, status: $?"
    done < $data
}

case "$1" in
    user-enabled)
    data=$2
    enable
    ;;
    user-disabled)
    data=$2
    disable
    ;;
    status)
    data=$2
    status
    ;;
    *)
    echo $"Usage: $prog {user-enabled|user-disabled|status} config file "
    RETVAL=1
esac

exit $RETVAL
