Alan,

Ok, I understand this event is for the expander on the HBA. Per your 
suggestion
I opened a ticket with LSI this AM, and, when I get something definitive 
will post
back.

If there is a sound FAQ on I2c, SGPIO, SES/SES-2, cabling along with 
common
problems and use cases I have not found it - I can dream though.

A lot of reading internet posts right or wrong and reading between the 
lines in manuals.

Or I may just be getting older.

Frustrating.

Thank you again.
