Cable your NS224 shelf to your AFF A320 system so that each shelf has two connections to each controller in the HA pair.

You can hot-add a second shelf to an existing HA pair when additional storage is needed.

Steps

  1. Cable the shelf to the controllers.

    1. Cable NSM A port e0a to controller A port e0e.

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

    3. Cable NSM B port e0a to controller B port e0e.

    4. Cable NSM B port e0b to controller A port e0b.
      The following illustration shows cabling for the hot-added shelf (shelf 2):

  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.
