Cable your NS224 shelf to your AFF A30, AFF A50, AFF C30, or AFF C60 system so that each shelf has two connections to each controller in the HA pair.

You can hot-add up to two NS224 shelves to an AFF A30, AFF C30, AFF A50, or AFF C60 HA pair when additional storage (to the internal shelf) is needed.

About this task

  • This procedure assumes that your HA pair has only internal storage (no external shelves) and that you are Hot-adding up to two additional shelves and two RoCE-capable I/O modules in each controller.

  • This procedure addresses the following hot-add scenarios:

    • Hot-adding the first shelf to an HA pair with one RoCE-capable I/O module in each controller.

    • Hot-adding the first shelf to an HA pair with two RoCE-capable I/O modules in each controller.

    • Hot- adding the second shelf to an HA pair with two RoCE-capable I/O modules in each controller.

  • These systems are compatible with both NS224 shelves with NSM100 modules and NS224 shelves with NSM100B modules. To ensure you cable your controllers to the correct ports, replace the "X" in each diagram with the correct port number for your module:

    Module type Port labeling

    NSM100

    "0"

    ex. e0a

    NSM100B

    "1"

    ex. e1a
Steps

  1. If you are hot-adding one shelf using one set of RoCE-capable ports (one RoCE-capable I/O module) in each controller module, 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 I/O module in slot 3.

    1. Cable shelf NSM A port eXa to controller A slot 3 port a (e3a).

    2. Cable shelf NSM A port eXb to controller B slot 3 port b (e3b).

    3. Cable shelf NSM B port eXa to controller B slot 3 port a (e3a).

    4. Cable shelf NSM B port eXb to controller A slot 3 port b (e3b).

      The following illustration shows cabling for one hot-added shelf using one RoCE-capable I/O module in each controller module:

  2. If you are hot-adding one or two shelves using two sets of RoCE-capable ports (two RoCE-capable I/O modules) in each controller module, complete the applicable substeps.

    Note This step assumes you installed the RoCE-capable I/O modules in slots 3 and 1.
    Shelves Cabling

    Shelf 1

    1. Cable NSM A port eXa to controller A slot 3 port a (e3a).

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

    3. Cable NSM B port eXa to controller B slot 3 port a (e3a).

    4. Cable NSM B port eXb to controller A slot 1 port b (e1b).

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

    The following illustration shows cabling for one hot-added shelf using two RoCE-capable I/O modules in each controller module:

    Cabling for AFF/ASA A30

    Shelf 2

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

    2. Cable NSM A port eXb to controller B slot 3 port b (e3b).

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

    4. Cable NSM B port eXb to controller A slot 3 port b (e3b).

    5. Go to the next step.

    The following illustration shows cabling for two hot-added shelf using two RoCE-capable I/O modules in each controller module:

    Cabling for AFF A30/ASA

  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.

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.
