Instructions

When running an API query for the PhysicalDisk field, the response contains a "state" key that does not appear in WSMAN similar query command, DCIM_PhysicalDiskView, as seen in the examples below.
The "state" key was added by accident, as it is not set or used by any component or entity in the system.
The "state" key and various values should be safely ignored.
