To map a WWPN to a port on an EMC Clariion service processor, the WWPN can be broke down
into three pieces:

      50:06:10                :60:                 10:F3:84
     EMC identifier        SP and Port #        WWN of the array

The second piece (fourth octet) 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 caswe of WWPN 50:06:10:60:10:F3:84, '60' would map to service process A, port 0.
