Rafal, Recently, we got an EMC V-max here in Poughkeepsie for testing. We had to do special configuration on the V-max to get point-to-point to work. Maybe one of the ports on the V-max is set up for point-to-point, and the other port isn't?

EMC JB: Are the link lights on? IIRC yes .. but to be sure I'm going to see it tomorrow. Is the fiber known to be good? IIRC yes, Storage admin tried different cables .. but of course I'm going to try it tomorrow again. Do the ports at both ends pass a wrap test? hmm.. I don't know about any tests ... we will do it tomorrow. Thanks one more time.
