Disable/Enable Servers via scripting

We run a clustered environment and we are trying to automate our maintenance process.

We would like to script out the disabling of all servers on one node.

We would then wait some time, apply the patches, and reboot the servers.

At that point we would then execute the script to re-enable the servers.

It doesn't look like we can do this via the RESTful services. Is there other scripting that we can use so the process of disabling/enabling the servers on the nodes can be automated?
