Storwize V7000 WWPNs - Port numbers now match WWPN

For those of you who have worked with SVC, you will be aware of a quirk when determining the WWPN of an SVC fibre channel port.
The WWPN of each fibre channel port is based on: 50:0
Port numbers (used for servicing) are always sequentially numbered left to right (viewed from the rear of the node). So the port numbers make sense.
The Storwize V7000 consists of two node canisters . The WWNN of each node canister will be based on 50:0
The WWPN of each Storwize V7000 fibre port is based on: 50:0
The number in each black box (which represents a fibre channel port) is the Y value. It is also the port number, This means the Y value and the port number are the same number. So for example, port 1 (the upper left hand most port), contains a 1, so a WWPN presented by this port would look like: 50:0
This makes more sense and fixes a 'feature' introduced with the 4F2 model of the SVC. Remember, that the z:zz:zz values for each node canister will be different (just like two SVC nodes had different z:zz:zz values for each node).
