When zoning hosts (actually HBA ports) to EMC Clariion SP ports, it is often beneficial to know which Clariion SP and port a WWPN is associated with. You can easily determine this by taking the Clariion WWPN (50:06:10:60:10:F3:84 in the following example) and breaking it down into three pieces:
EMC identifier => 50:06:10
SP and Port # => :60:
WWN of the array => 10:F3:84
The fourth octet (e.g., 60 in this example) contains the port and service processor, which can be identified by comparing the value to the following chart:
60 - SPA port 0
61 - SPA port 1
62 - SPA port 2
63 - SPA port 3
68 - SPB port 0
69 - SPB port 1
6A - SPB port 2
6B - SPB port 3
So in the case of WWPN 50:06:10:60:10:F3:84, the value 60 would map to service process A, port 0. Hopefully this information will save someone a walk to their data center (walking is good exercise, so I probably shouldn’t have posted this). :)
