Cabling a hot-add shelf for an AFF A800 HA pair

How you cable an NS224 drive shelf in an AFF A800 HA pair depends on the number of shelves you are hot-adding and the number of RoCE capable port sets you are using on the controllers.

Before you begin

Steps

  1. If you are hot-adding one shelf using one set of RoCE capable ports on each controller, and this is the only NS224 shelf in your HA pair, complete the following substeps.
    Otherwise, go to the next step.
    Note: This step assumes you installed the RoCE capable PCIe card in slot 5.
    1. Cable shelf NSM A port e0a to controller A slot 5 port 1 (e5a).
    2. Cable shelf NSM A port e0b to controller B slot 5 port 2 (e5b).
    3. Cable shelf NSM B port e0a to controller B slot 5 port 1 (e5a).
    4. Cable shelf NSM B port e0b to controller A slot 5 port 2 (e5b).
    Example
    The following illustration shows cabling for one hot-added shelf using one set of RoCE capable ports on each controller:

  2. If you are hot-adding one or two shelves using two sets of RoCE capable ports on each controller, complete the applicable substeps.
    Note: This step assumes you installed the RoCE capable PCIe cards in slot 3 and slot 5.
    Shelves Cabling
    Shelf 1
    Note: These substeps assume you are beginning the cabling by cabling shelf port e0a to the RoCE capable PCIe card in slot 5, instead of slot 3.
    1. Cable NSM A port e0a to controller A slot 5 port 1 (e5a).
    2. Cable NSM A port e0b to controller B slot 3 port 2 (e3b).
    3. Cable NSM B port e0a to controller B slot 5 port 1 (e5a).
    4. Cable NSM B port e0b to controller A slot 3 port 2 (e3b).
    5. If you are hot-adding a second shelf, complete the "Shelf 2" substeps; otherwise, go to step 3.
    Shelf 2
    Note: These substeps assume you are beginning the cabling by cabling shelf port e0a to the RoCE capable PCIe card in slot 3, instead of slot 5 (which correlates with the cabling substeps for shelf 1).
    1. Cable NSM A port e0a to controller A slot 3 port 1 (e3a).
    2. Cable NSM A port e0b to controller B slot 5 port 2 (e5b).
    3. Cable NSM B port e0a to controller B slot 3 port 1 (e3a).
    4. Cable NSM B port e0b to controller A slot 5 port 2 (e5b).
    5. Go to step 3.
    Example
    The following illustration shows cabling for two hot-added shelves:

  3. Verify that the hot-added shelf is cabled correctly.
    If any cabling errors are generated, follow the corrective actions provided.

  4. If you disabled automatic drive assignment as part of the preparation for this procedure, you need to manually assign drive ownership and then reenable automatic drive assignment, if needed.
    Otherwise, you are done with this procedure.
