Determine the new cabling layout
Contributors Download PDF of this page
You must determine the cabling for the new controller modules and any new disk shelves to the existing FC switches.
This task must be performed at each MetroCluster site.
Use the Fabric-attached MetroCluster Installation and Configuration Guide to determine the cabling layout for your switch type, using the port usage for an eight-node MetroCluster configuration. The FC switch port usage must match the usage described in the guide so that the Reference Configuration Files (RCFs) can be used.

|If your environment cannot be cabled in a way that RCFs can be used, then contact technical support. Do not use this procedure if the cabling cannot use RCFs.|
