PERSISTENT RESERVATION IN Command (5Eh)

The PERSISTENT RESERVATION IN command is a 10-byte command used to
obtain information about persistent reservations and reservations that are active within
a device server. It is used in conjunction with the PERSISTENT RESERVATION
OUT command.
Note that a if device that has RESERVE (10), RESERVE (6), extent reservations, or
SCSI Media Changer (SMC) element reservations active receives a PERSISTENT
RESERVATION IN command, the PERSISTENT RESERVATION IN
command is rejected with a RESERVATION CONFLICT status reported.
Table 5-102 illustrates the format of the PERSISTENT RESERVATION IN
command. Table 5-103 explains the data fields of the command.
