Preparing an AFF A800 or AFF A400 HA pair to hot-add a second shelf

If you have an AFF A800 or AFF A400 HA pair with one NS224 drive shelf that is cabled to one set of RoCE capable ports on each controller, you must recable the shelf (after you have installed the additional RoCE capable PCIe cards) across both sets of ports on each controller, before hot-adding the second shelf.

About this task

Steps

  1. Recable the existing shelf's connections across both sets of ports on each controller, as applicable to your platform model.
    Note: Moving a cable does not require any wait time between unplugging the cable from one port and plugging it into another port.

    Note: The substeps assume the existing shelf is cabled to RoCE capable PCIe cards in slot 5 on each controller.
    Note: If needed, you can reference cabling illustrations showing an existing single shelf and the recabled shelf, in a two shelf configuration.

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

    1. On controller B, move the cable from slot 5 port 2 (e5b) to slot 3 port 2 (e3b).
    2. On controller A, move the cable from slot 5 port 2 (e5b) to slot 3 port 2 (e3b).

    Cabling a hot-add shelf for an AFF A400 HA pair

    1. On controller B, move the cable from port e0d to slot 5 Port 2 (e5b).
    2. On controller A, move the cable from port e0d to slot 5 port 2 (e5b).
  2. Verify that the recabled shelf is cabled correctly.
    If any cabling errors are generated, follow the corrective actions provided.
