If the
3rd pty bit is 0, the initiator reserves the drive for itself. If
the 3rd pty bit is 1, the initiator reserves the drive for another
initiator. The SCSI ID of the third-party initiator is specified in the
3rd party device ID field.
The
extent bit must always be 0. The drive does not support
extent reservations. If the extent bit is 1, the drive generates a
check condition status.
3.4.12 Release (6) command (17
H
)
When an initiator that had reserved the drive using the Reserve com-
mand issues the Release command, it cancels the reservation. If the
drive is not currently reserved or is reserved by another initiator and it
receives a Release command, the drive returns a good status and
maintains the reservation.
Note.
For the ST52160WC, the Release (6) command cannot release
SCSI ID’s 8–15. Use the Release (10) command.
