HI there...

I have newly deployed HP MSA1040 SAN with 2 DL380 G9 for Hyper-V cluster setup.
I have connected the array directly to server using SAS cable and the volumes able present to servers. however from MSA GUI, I can see there are warning about the SAS connection.

the error was something like "the cable connected is not match with the fan-out mode". I have search though Google and not much info about this.

Another thing, when I did cluster validation, it say no disk found.

appreciate any help..

Part numbers for the cables would help -- as would photos of them.  
Perhaps screen shots or an exact transcription of the error message -- sometimes there is a huge difference between two "something like..."s.
And sometimes a cabling diagram is important for troubleshooting.
Which document were you following when you cabled this thing up?
Are you using only the MSA "head", or do you have expansion shelves, too?

Hi SelfGovern,

thanks for the response...

Actually found to be the SAS cable I have is standard cable, however the array was enabled with fan-out mode at its ports.
So, just simply uncheck the fan-out mode and restart the array and thing just get resolved.

thanks

Just for info the MSA1040 has two SAS host ports per controller but you can connect up to four hosts to those two ports if you use the bifurcated SAS fan-out cables. That's an improvement on some previous SAS-connected MSA arrays that just allowed for a two node cluster.

Found out is the array has fan-out mode option enabled.
