#run_script_on_instances(script, ec2_instance_hrefs = [], opts = {}) ⇒ Object

Run a script on individual instances in a ServerArray

This was formerly located in Ec2ServerArrayInternal but has been moved here to Ec2ServerArray as the call has been ported from API 0.1 to API 1.0.

Example: array.run_script_on_instances(right_script, server_href, options_hash)
