Cabling the FC-VI and HBA ports in a two-node fabric-attached MetroCluster configuration with array LUNs
If you are setting up a two-node fabric-attached MetroCluster configuration with array LUNs, you must cable the FC-VI ports and the HBA ports to the switch ports.
You must repeat this task for each controller at both of the MetroCluster sites.
If you plan to use disks in addition to array LUNs in your MetroCluster configuration, you must use the HBA ports and switch ports specified for configuration with disks.
Cable the FC-VI ports from the controller to alternate switch ports.
Perform the controller-to-switch cabling at both of the MetroCluster sites.
You must ensure redundancy in connections from the controller to the switches. Therefore, for each controller at a site, you must ensure that both of the HBA ports in the same port pair are connected to alternate FC switches.
The following example shows the connections between the HBA ports on Controller A and ports on FC_switch_A_1 and FC_switch_A_2:
The following table lists the connections between the HBA ports and the FC switch ports in the illustration:
FC_switch_A_1, Port 2
FC_switch_A_2, Port 3
FC_switch_A_2, Port 2
FC_switch_A_1, Port 3
You should cable the ISLs between the FC switches across the MetroCluster sites.
