The PERSISTENT RESERVE IN command is used to obtain information about persistent reservations and reservation keys
that are active within the controller. This command is used in conjunction with the PERSISTENT RESERVE OUT command
"PERSISTENT RESERVE OUT (5F)" on page 201.
The Allocation Length indicates how much space has been allocated for the returned parameter list. If the length is not suffi-
cient to contain all parameter data, the first portion of the data will be returned. If the remainder of the data is required, the ini-
tiator should send a new PERSISTENT RESERVE IN command and an Allocation Length large enough to contain all data.
