Fibre-channel port numbers and worldwide port names
Fibre-channel ports are identified by their physical port number and by a
worldwide port name (WWPN).
The physical port numbers identify fibre-channel cards and cable connections
when you perform service tasks. The WWPNs are used for tasks such as
fibre-channel switch configuration and to uniquely identify the devices on the
SAN.
The physical port numbers are 1 - 4, counting from left to right when you view the
rear panel of the SAN Volume Controller. The WWPNs are derived from the
worldwide node name (WWNN) of the SAN Volume Controller in which the card
is installed.
The WWNN is in the form 50050768010XXXXX, where XXXXX is initially derived
from the unit and is specific to a SAN Volume Controller. You can change the
XXXXX value by using the front panel to facilitate service controller concurrent
replacement and to enable some concurrent upgrade operations.
The WWPNs are in the form 5005076801QXXXXX, where XXXXX is as previously
stated and Q is related to the port number as follows:
