Info

hover the mouse over a port, as shown in Figure 4-47. This view displays all the informationthat is shown in Figure 4-46 on page 115.Figure 4-47 Port information from the patch panel viewSimilar information can be displayed for the iSCSI connections using the GUI, as shown inFigure 4-48. This view can be seen either by right-clicking the Ethernet port (similar to theFibre Channel port shown in Figure 4-47) or by selecting the system, then selecting Hostsand LUNs iSCSI Connectivity. This sequence displays the same two iSCSI definitionsthat are shown with the XCLI command.Figure 4-48 iSCSI connectivityBy default, Fibre Channel ports 2 and 4 (target and initiator, respectively) from every moduleare designed to be used for Remote Mirroring. For example, port 4 module 8 (initiator) on thelocal machine is connected to port 2 module 8 (target) on the remote machine. When settingup a new system, it is best to plan for any Remote Mirroring and reserve these ports for thatpurpose. However different ports could be used as needed.116 IBM XIV Storage System: Copy Services and Migration
In the event that a port role does need to be changed, you can change the port role with boththe XCLI and the GUI. Use the XCLI fc_port_config command to change a port, as shown inExample 4-3. Using the output from fc_port_list, we can get the fc_port name to be used inthe command, changing the port role to be either initiator or target, as needed.Example 4-3 XCLI command to configure a portfc_port_config fc_port=1:FC_Port:4:3 role=initiatorCommand completed successfullyfc_port_listComponent ID Status Currently Functioning WWPNPort ID Role1:FC_Port:4:3 OK yes 5001738000130142 00750029 InitiatorTo perform the same function with the GUI, select the primary system, open the patch panelview, and right-click the port, as shown in Figure 4-49.Figure 4-49 Configure portsChapter 4.
