Racking the hardware components

Contributors netapp-aoife netapp-thomi

If you have not received the equipment already installed in cabinets, you must rack the components.

About this task

This task must be performed on both MetroCluster sites.

  1. Plan out the positioning of the MetroCluster components.

    The rack space depends on the platform model of the controller modules, the switch types, and the number of disk shelf stacks in your configuration.

  2. Properly ground yourself.

  3. Install the controller modules in the rack or cabinet.

  4. Install the FC switches in the rack or cabinet.

  5. Install the disk shelves, power them on, and then set the shelf IDs.

    • You must power-cycle each disk shelf.

    • Shelf IDs must be unique for each SAS disk shelf within each MetroCluster DR group (including both sites).

  6. Install each FC-to-SAS bridge:

    1. Secure the “L” brackets on the front of the bridge to the front of the rack (flush-mount) with the four screws.

      The openings in the bridge “L” brackets are compliant with rack standard ETA-310-X for 19-inch (482.6 mm) racks.

      The ATTO FibreBridge Installation and Operation Manual for your bridge model contains more information and an illustration of the installation.

      Note For adequate port space access and FRU serviceability, you must leave 1U space below the bridge pair and cover this space with a tool-less blanking panel.
    2. Connect each bridge to a power source that provides a proper ground.

    3. Power on each bridge.

      Note For maximum resiliency, bridges that are attached to the same stack of disk shelves must be connected to different power sources.

      The bridge Ready LED might take up to 30 seconds to illuminate, indicating that the bridge has completed its power-on self test sequence.
