MetroCluster Manuals ( CA08871-401 )
Using the port tables with the RcfFileGenerator tool or multiple MetroCluster configurations
You must understand how to use the information in the port tables to correctly generate your RCF files.
Review these considerations before using the tables:
-
The following tables show the port usage for site A. The same cabling is used for site B.
-
The switches cannot be configured with ports of different speeds (for example, a mix of 100 Gbps ports and 40 Gbps ports).
-
Keep track of the MetroCluster port group (MetroCluster 1, MetroCluster 2, etc.). You will need this information when using the RcfFileGenerator tool as described later in this configuration procedure.
-
Please contact our technical support personnel to ask for a per-port cabling overview for each switch. Use this cabling overview to verify your cabling.
Cabling eight-node MetroCluster configurations
For MetroCluster configuration running ONTAP 9.8 and earlier, some procedures that are performed to transition an upgrade require the addition of a second four-node DR group to the configuration to create a temporary eight-node configuration. Beginning with ONTAP 9.9.1, permanent eight-node MetroCluster configurations are supported.
For such configurations, you use the same method as described above. Instead of a second MetroCluster, you are cabling an additional four-node DR group.
For example, your configuration includes the following:
-
Cisco 3132Q-V switches
-
MetroCluster 1: ETERNUS HX2200 series
-
For MetroCluster 1, cable the Cisco 3132Q-V switches using the table for the ETERNUS HX2200 series and the rows for MetroCluster 1 interfaces.
