Cable your NS224 shelf to your FAS500f system so that each shelf has two connections to each controller in the HA pair.

When additional storage is needed, you can hot-add one NS224 shelf to a FAS500f HA pair.

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.
