This message is typically due to a loop in the SAS topology. You should make sure you have the system cabled correctly.

hi everyone

I hooked a sas3 chassis to Perc H800 and first thing, controller moans:

"Invalid SAS topology detected. Please check your cable configurations, repair the problem, and restart your system"

Has somebody seen it? I wonder how much o a dysfunctional array that makes it.
