The Fibre Channel ports for the system can be viewed by navigating to  Settings  Network  and opening the  Fibre Channel Ports  menu, as shown in Figure 4-44. Port numbers refer to  the Fibre Channel I/O port IDs. To see the Fibre Channel connectivity of the system, navigate to  Settings  Network  and  open the  Fibre Channel Connectivity  menu, as shown in Figure 4-45. The window displays  the connectivity between nodes and other storage systems and hosts that are attached  through the Fibre Channel network. When replacing or upgrading your node hardware to newer models, consider that the number  of Fibre Channel ports and their arrangement might have changed. If this is the case, make  sure that any configured port masks are still valid for the new configuration.
