If the initiator does not set the Additional Page Length field of the Mode Page to the
value indicated in the Mode Page definition (for example, 10h for the Device
Configuration Page), the drive terminates the Mode Select command and returns
Check Condition status bytes with an Illegal Request sense key. The Additional
Sense Code and Additional Sense Code Qualifier are set to Invalid Field in
Parameter List.
The Disconnect/Reconnect page allows the host to set the maximum burst size for
data transfer.
