Members
Generation[4]
The Generation field contains a 32-bit counter that is maintained by the device server, which is incremented every time a Persistent Reserve Out command requests a REGISTER, REGISTER AND IGNORE EXISTING KEY, CLEAR, PREEMPT, or PREEMPT AND ABORT service action.
AdditionalLength[4]
The AdditionalLength field contains a count of the number of bytes in the reservation key list.
ReservationKeyList[0]
The reservation key list contains the 8-byte reservation keys for all initiators that have registered by using all ports with the device server.
Remarks
The IOCTL_STORAGE_PERSISTENT_RESERVE_IN request is used to obtain information about persistent reservations and reservation keys that are active within a device server.
