A Page Code Valid (PF) bit of one indicates that the parameters conform to the page structure as
specified in the standard. Users of the ATTO FibreBridge should always set PF to 1.
Setting the SelfTest bit in conjunction with the DevOffL bit causes the ATTO FibreBridge to reset itself,
perform power on self-test, then continue operation. To avoid possible command errors in multi-initiator
systems, The ATTO FibreBridge should be RESERVED before issuing a SelfTest Command.
The SEND DIAGNOSTIC parameter list must contain Control data, in the format of the Enclosure Control
page, in order to complete properly. Note that the complete Enclosure Control page must be sent with
every SEND DIAGNOSTIC command.
