Hi Experts,
I am not sure this is the appropriate mail alias to send my question about
SAS.
If it's not. Sorry about my forwardness.
I didn't get solid understanding about SAS address of a wide port.
When single or multiple PHYs of a wide port get hardware error, should the
SAS address of the wide port still keep consistent with the previous one
which is the address when all PHYs were available?
Thanks
Javen
