You cable each NS224 shelf you are hot-adding so that each shelf has two connections to each controller in the HA pair.

Cable shelf to ASA A250 or ASA C250

When additional storage is needed, you can hot-add a maximum of one NS224 shelf to an AFF A250 or AFF C250 HA pair.

Before you begin
About this task

When viewed from the rear of the platform chassis, the RoCE-capable card port on the left is port "a" (e1a) and the port on the right is port "b" (e1b).

Steps

  1. Cable the shelf connections:

    1. Cable shelf NSM A port e0a to controller A slot 1 port a (e1a).

    2. Cable shelf NSM A port e0b to controller B slot 1 port b (e1b).

    3. Cable shelf NSM B port e0a to controller B slot 1 port a (e1a).

    4. Cable shelf NSM B port e0b to controller A slot 1 port b (e1b).
      The following illustration shows the shelf cabling when completed.

  2. Verify that the hot-added shelf is cabled correctly using Active IQ Config Advisor.

    If any cabling errors are generated, follow the corrective actions provided.

What's next?

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. Go to Complete the hot-add.

Otherwise, you are done with the hot-add shelf procedure.

Cable shelf to ASA A400 or ASA C400

How you cable an NS224 shelf for a hot-add depends on whether you have an AFF A400 or AFF C400 HA pair.

Before you begin

Cable shelf to an AFF A400 HA pair

For an AFF A400 HA pair, you can hot-add up to two shelves and use onboard ports e0c/e0d and ports in slot 5 as needed.

Steps

  1. If you are hot-adding one shelf using one set of RoCE-capable ports (onboard 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.

    1. Cable shelf NSM A port e0a to controller A port e0c.

    2. Cable shelf NSM A port e0b to controller B port e0d.

    3. Cable shelf NSM B port e0a to controller B port e0c.

    4. Cable shelf NSM B port e0b to controller A port e0d.

      The following illustration shows cabling for one hot-added shelf using one set of RoCE-capable ports on each controller:

    4. Cable NSM B port e0b to controller A slot 5 port 2 (e5b).

    5. If you are hot-adding a second shelf, complete the “Shelf 2” substeps; otherwise, go to step 3.

    Shelf 2

    1. Cable NSM A port e0a to controller A slot 5 port 1 (e5a).

    2. Cable NSM A port e0b to controller B port e0d.

    3. Cable NSM B port e0a to controller B slot 5 port 1 (e5a).

    4. Cable NSM B port e0b to controller A port e0d.

  3. Verify that the hot-added shelf is cabled correctly using Active IQ Config Advisor.

    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 re enable automatic drive assignment, if needed. See Complete the hot-add.

    Otherwise, you are done with this procedure.

Cable shelf to an AFF C400 HA pair

For an AFF C400 HA pair, you can hot-add up to two shelves and use ports in slot 4 and 5 as needed.

Cable shelf to ASA A800 or ASA C800

How you cable an NS224 shelf in an AFF A800 or AFF C800 HA pair depends on the number of shelves you are hot-adding and the number of RoCE-capable port sets (one or two) 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 (one RoCE-capable PCIe card) 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 a (e5a).

    2. Cable shelf NSM A port e0b to controller B slot 5 port b (e5b).

  2. If you are hot-adding one or two shelves using two sets of RoCE-capable ports (two RoCE-capable PCIe cards) on each controller, complete the applicable substeps.

    Note This step assumes you installed the RoCE-capable PCIe cards in slot 5 and slot 3.
    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.

    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 a (e3a).
