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 WWPNs are derived from the worldwide node name (WWNN) that is
allocated to the Storwize V7000 node in which the ports are installed. The WWNN
for each node is stored within the enclosure. When you replace a node canister, the
WWPNs of the ports do not change.
The WWNN is in the form 50050768020
XXXXX
, where
XXXXX
is specific to an
enclosure.
USB ports
Two USB ports are located side by side on each node canister.
The USB ports are numbered 1 on the left and 2 on the right as shown in Figure 14
on page 11. One port is used during installation.
