• READ KEYS
The READ KEYS service action requests that the device server return a
parameter list containing a header and a list of each currently registered initiator's
reservation key.
If multiple initiators have registered with the same key, then that key value shall
be listed multiple times, once for each such registration.
• READ RESERVATIONS
The READ RESERVATIONS service action requests that the device server return
a parameter list containing a header and the persistent reservation(s), if any, that
is present in the device server. Multiple persistent reservations may be returned
only if element reservations are present.
