Field Description

Service

Action

A service action of 05h identifies this as the REPORT DEVICE IDENTIFIER

command.

Allocation

Length

If the Allocation Length is not large enough to hold all of the parameter data, the

drive truncates the data it returns. This is not 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 must send a new REPORT DEVICE IDENTIFIER command with a value

in the Allocation Length field large enough to hold all of the data.
