Storage Processor Ports WWNs 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 Clariions SPA Port 0 World Wide Name would start off
50:06:01:60. And every Clariions 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. Lets 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
Clariions SP A Port 0 would be 50:06:01:60:10:60:08:74, and the
Development Clariions SP A Port 0 would be
50:06:01:60:10:60:06:23.
