RESTful API Support • Allows an HTTP-based interface to manage the array Command Effect Similar to HTTP GET Retrieves and lists existing configuration of an object or multiple objects. XMS CLI ‘show’ commands HTTP POST Creates a new configuration for an object. XMS CLI ‘add’ commands HTTP PUT Updates the existing configuration for an object. XMS CLI ‘modify’ commands HTTP DELETE Deletes the existing configuration of an object. XMS CLI ‘remove’ commands • Uses the Java.
