Each Storage Processor Port will have a unique World Wide Name associated with it. What we are doing on this page is to “break down” what makes up the SP Port WWN. What I am showing here are the three(3) pieces that make up the WWN. The three(3) pieces are what I am calling the ‘EMC Flag’, the SP Port Identifier, and the Array ID. All SP Port WWNs on Clariions start with the same ‘EMC Flag’ of 50:06:01. When you are looking at the Switch Software that shows the ports on the switch and what is plugged into those ports, anytime you see a World Wide Name that starts with the 50:06:01, you will know that a Clariion SP Port is connected there.
The next “piece” to the World Wide Name, is the SP Port Identifier. On all Clariions, these numbers are the same as well. For instance, if you have 3 Clariions in your environment, every one of those Clariion’s SPA Port 0 World Wide Name would start off 50:06:01:60. And every Clariion’s SP B Port 1 would start off 50:06:01:69. These SP Port Identifiers will not change from Clariion to Clariion.
The last “piece” to the puzzle is the Array ID. This is related to the Unique ID of the Clariion itself. Every Clariion has a unique World Wide Name associated with it. But, that Array ID belongs to every port on that Clariion as it shows above. Now, if you have two(2) Clariions in your environment, you will see two(2) sets of Array IDs. Let’s say you have a Production Clariion and a Development Clariion (I know, no one has that), the Production Clariion could have an Array ID of 10:60:08:74, and the Development Clariion could have an Array ID of 10:60:06:23. So, the Production Clariion’s SP A Port 0 would be 50:06:01:60:10:60:08:74, and the Development Clariion’s SP A Port 0 would be 50:06:01:60:10:60:06:23.
