The "Reservation Key" field contains an 8-byte key code provided by the application client to identify the initiator that is the source of the PERSISTENT RESERVE OUT command. The drive checks whether the contents of the "Reservation Key" field received with the PERSISTENT RESERVE OUT command matches the Reservation Key registered by the INIT that has issued the command. However, if all the registered Reservation Keys are zero (not registered), the value specified in this field is ignored. If a key that is different from the Reservation Key for the relevant INIT is specified by the PERSISTENT RESERVE OUT command, the drive reports a RESERVATION CONFLICT status. All the Reservation Keys of this INIT are valid for Service Actions and scopes.
