You can add an I/O module to your AFF A900 storage system when there are empty slots available or when all slots are fully populated.

Step 1: Shut down the impaired controller module

Shut down or take over the impaired controller module.

Option 1: Most systems

To shut down the impaired controller, you must determine the status of the controller and, if necessary, take over the controller so that the healthy controller continues to serve data from the impaired controller storage.

Before you begin

If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a healthy controller shows false for eligibility and health, you must correct the issue before shutting down the impaired controller; see Synchronize a node with the cluster.

Steps

  1. If AutoSupport is enabled, suppress automatic case creation by invoking an AutoSupport message command: system node autosupport invoke -node * -type all -message MAINT=number_of_hours_downh

    The following AutoSupport command suppresses automatic case creation for two hours: cluster1:*> system node autosupport invoke -node * -type all -message MAINT=2h

  2. Disable automatic giveback from the console of the healthy controller: storage failover modify –node local -auto-giveback false

  3. Take the impaired controller to the LOADER prompt:

    If the impaired controller is displaying…​ Then…​

    The LOADER prompt

    Go to the next step.

    Waiting for giveback…​

    Press Ctrl-C, and then respond y when prompted.

    System prompt or password prompt (enter system password)

    Halt or take over the impaired controller from the healthy controller: storage failover takeover -ofnode impaired_node_name

    When the impaired controller shows Waiting for giveback…​, press Ctrl-C, and then respond y.

Step 2: Add the new I/O module

If the storage system has empty slots, install the new I/O module into one of the available slots. If all slots are occupied, remove an existing I/O module to make space and then install the new one.

Before you begin

  • Check the NetApp Hardware Universe to make sure that the new I/O module is compatible with your system and version of ONTAP you're running.

  • If multiple slots are available, check the slot priorities in NetApp Hardware Universe and use the best one available for your I/O module.

  • To non-disruptively add an I/O module, you must take over the target controller, remove the slot blanking cover in the target slot or remove an existing I/O module, add the new or replacement I/O module, and then giveback the target controller.

  • Make sure that all other components are functioning properly.

Add I/O module to an empty slot

You can add a new I/O module into a storage system with available empty slots.

Steps

  1. If you are not already grounded, properly ground yourself.

  2. Remove the target slot blanking cover:

    1. Depress the lettered and numbered cam latch.

    2. Rotate the cam latch down until it is the open position.

    3. Remove the blanking cover.

  3. Install the I/O module:

    1. Align the I/O module with the edges of the slot.

    2. Slide the I/O module into the slot until the lettered and numbered I/O cam latch begins to engage with the I/O cam pin.

    3. Push the I/O cam latch all the way up to lock the module in place.

  4. If the replacement I/O module is a NIC, cable the module to the data switches.

    Note Make sure that any unused I/O slots have blanks installed to prevent possible thermal issues.

  5. Reboot the controller from the LOADER prompt: bye

    Note This reinitializes the PCIe cards and other components and reboots the node.

  6. Give back the controller from the partner controller. storage failover giveback -ofnode target_node_name

  7. Enable automatic giveback if it was disabled: storage failover modify -node local -auto-giveback true

  8. If you are using slots 3 and/or 7 for networking, use the storage port modify -node <node name> -port <port name> -mode network command to convert the slot for networking use.

  9. Repeat these steps for controller B.

  10. If you installed a storage I/O module, install and cable your NS224 shelves, as described in Hot-add workflow.
