Table 47 Persistent
Reserve Out
Parameter List
Field Name Description
Reservation This field contains an 8-byte token that is provided by the application client to
Key the device server to identify which initiator is the source of the PERSISTENT
RESERVE OUT command. For all service actions except Register and Ignore
Existing Key, the device server verifies that the Reservation Key in the
PERSISTENT RESERVE OUT command matches the Reservation Key that is
registered for the initiator from which the command is received. If there is no
match, the device server returns a RESERVATION CONFLICT status. The
Reservation Key of the initiator is valid for all Service action and Scope
values.
Service Action This field contains information needed for 3 service actions: the Register
Reservation service action, the Pre-empt service action, and the Pre-empt & Clear service
Key action. The Service Action Reservation Key is ignored for all other service
actions.
For the Register service action, the Service Action Reservation Key field
contains the new Reservation Key to be registered.
For the Pre-empt and the Pre-empt & Clear service actions, the Service Action
Reservation Key contains the reservation key of the persistent reservations
that are being pre-empted. For the Pre-empt and the Pre-empt & Clear
actions, any failure of the Service Action Reservation Key to match any
registered keys results in the device server returning a RESERVATION
CONFLICT status.
