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.
