Asynchronous events at the target

[sanquery <sanquery@myrealbox.com>]

Hi all,
  I wanted to know is there any means by which an initiator can be notified of some asynchronous events at the target. 
 According to SAM2(Page 73), Asynchronous Event Reporting takes place when one of the following events occur:
a)An exception condition was encountered after command completion;
b)A newly initialized device is available;
c)Some other type of unit attention condition has occured; or
d)An asynchronous event has occured.

How does the notification for a newly initialized device available at the target go to the Initiator? Is it done by suddenly sending an Asynchronous PDU with an Async Event value of 0 corresponding to Sense Data? Or is there any other means of handling this notification?

Regards,
Sanquery.
