Script to force-offline and enable nodes

[Cowboy Denny]

This script is created to make it easy to force-offline a node or pool member and then reenable it.

Create a file called node-maint.sh and paste the following

#!/bin/bash
# format to follow:
# $1 node-enable|node-forceoffline|poolnode-enable|poolnode-forceoffline
# $2 node-ipaddress|node-fqdn|member ip/fqdn and port
# example node: node-maint.sh node-forceoffline 10.6.0.141
# example node: node-maint.sh node-enable 10.6.0.141
# example member: node-maint.sh poolnode-forceoffline
# example member: node-maint.sh poolnode-enable /Production/10.40.152.116:8101 /Production/pool.alfa-fnt.hosangit.com.8101

echo "******* HELP *********"
echo "ACTION options are:"
echo "node-enable or node-forceoffline"

echo "NODE options are:"
echo "ip address or fqnd (you have to use however its configured)"
echo "POOL MEMBER options are:"
