Allocation If the Allocation Length is not sufficient to contain all the
Length parameter data, the first portion of the data shall be
returned. This shall not be considered an error. The
actual length of the parameter data is available in the
Identifier Length field in the parameter data. If the
remainder of the parameter data is required, the
application client should send a new REPORT DEVICE
IDENTIFIER command with an Allocation Length field
large enough to contain all the data.
The REPORT DEVICE IDENTIFIER parameter list contains a four-
byte field that contains the length in bytes of the parameter list and
the logical unit's identifier.
