This command is used to obtain information about persistent reservations and reservation keys that
are active within a device server. This command is used in conjunction with the PERSISTENT
RESERVE OUT command (see 3.1.19).
The actual length of the PERSISTENT RESERVE IN parameter data is available in a parameter
data field. The "Alloation Length" field in the CDB indicates how much space has been reserved
for the returned parameter list. If the length is not sufficient to contain the entire parameter list, the
first portion of the list shall be returned. This shall not be considered an error. If the remainder of
the list is required, the application client should send a new this command with a "Allocation
Length" field large enough to contain the entire list.
