Do I need to set 3PAR host port to "loop" to direct connect a server to the 3PAR?

Do I need to set 3PAR host port to "loop" to direct connect a server to the 3PAR?

We have been direct-connecting Linux servers to 3PAR Host Ports for some time.  The other day we found an entry in the W2K12 Implementation Guide that said if we direct-connect a Windows Server to the HP 3PAR, we must set the Host Ports to "loop", i.e.:

 

# controlport offline 1:5:1

# controlport config host -ct loop 1:5:1

# controlport rst 1:5:1

 

You can see settings ("loop" or "point") with command:

 

# showport -par

 

So, the question is:  Is this really true?  Do I have to really set the Host Port to Loop?  Why for W2K12 and not for Linux?
