Cabling the redundant multipath HA connection for each loop

To complete the multipath HA cabling for the disk shelves, you must add the final connection for each channel on the final disk shelf in each loop.

  1. Review the cabling diagram before proceeding to the cabling steps.
    • The circled numbers in the diagram correspond to the step numbers in the procedure.
    • The location of the Input and Output ports on the disk shelves vary depending on the disk shelf models.

      Make sure that you refer to the labeling on the disk shelf rather than to the location of the port shown in the diagram.

    • The location of the Fibre Channel ports on the controllers is not representative of any particular storage system model; determine the locations of the ports you are using in your configuration by inspection or by using the Installation and Setup Instructions for your model.
    • The port numbers refer to the list of Fibre Channel ports you created.
    • The diagram only shows one loop per node and one disk shelf per loop.

      Your installation might have more loops, more disk shelves, or different numbers of disk shelves between nodes.

  2. Connect the Channel A output port on the last disk shelf for each loop belonging to Node A to an available port on Node B in the same pool.
  3. Connect the Channel B output port on the last disk shelf for each loop belonging to Node A to an available port on Node B in the same pool.
  4. Connect the Channel A output port on the last disk shelf for each loop belonging to Node B to an available port on Node B in the same pool.
  5. Connect the Channel B output port on the last disk shelf for each loop belonging to Node B to an available port on Node B in the same pool.
