Connecting the fabric and storage array in a MetroCluster configuration with array LUNs

All storage arrays, regardless of model, must be configured to allow Data ONTAP to access a specific LUN on two (primary and secondary) storage array ports.

  • The local and remote Data ONTAP systems must be connected to the fabric.
  • The fabric must be connected and the switches must be powered up.
  • Your storage array documentation verified that the ports you plan to use do not access more than the number of array LUNs and host groups that are supported for that storage array model.

The following illustration provides a reference for connecting the fabric and the storage arrays:

This graphic is described by the surrounding text.
  1. Connect the ports on the storage array at Site A:
    1. Connect storage array controller 1A to any port on one fabric. In the sample illustration, this is Switch 1, Port 4, Fabric 1.
    2. Connect controller 2A to any port on the alternate fabric. In the sample illustration this is Switch 2, Port 15, Fabric 2.
    3. Connect storage array controller 1B to any port on one fabric. In the sample illustration, this is Switch 1, Port 6, Fabric 1.
    4. Connect controller 2B to any port on the alternate fabric. In the sample illustration this is Switch 2, Port 16, Fabric 2.
    5. Connect additional controller ports and fabrics, as required by your MetroCluster configuration.
  2. Connect the ports on the storage array at Site B:
    1. Connect storage array controller 1A to any port on one fabric. In the sample illustration, this is Switch 3, Port 9, Fabric 1.
    2. Connect controller 2A to any port on the alternate fabric. In the sample illustration, this is Switch 4, Port 20, Fabric 2.
    3. Connect additional controller ports and fabric, as required by your MetroCluster configuration.
    4. Connect storage array controller 1B to any port on one fabric. In the sample illustration, this is Switch 3, Port 11, Fabric 1.
    5. Connect controller 2B to any port on the alternate fabric. In the sample illustration, this is Switch 4, Port 21, Fabric 2.
