Add an I/O module - AFF A900

Contributors dougthomp

You can add an I/O module to your system by either replacing a NIC or storage adapter with a new one in a fully-populated system, or by adding a new NIC or storage adapter into an empty chassis slot in your system.

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.

Option 1: Add the I/O module to a system with open slots

You can add an I/O module into an empty module slot in your system as either a NIC or a storage module for the NS224 storage shelves.

  1. Shutdown controller A:

    1. Disable automatic giveback: storage failover modify -node local -auto-giveback false

    2. Take over the target controller: storage failover takeover -ofnode target_node_name

      The console connection shows that the controller drops to the LOADER prompt when the take over is complete.

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

  3. Remove the target slot blanking cover:

    1. Depress the lettered and numbered cam button.

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

    3. Remove the blanking cover.

  4. 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.

  5. 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.
  6. Reboot the controller from the LOADER prompt: bye

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

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

  9. 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.

  10. Repeat these steps for controller B.

  11. If you installed a storage I/O module, install and cable your NS224 shelves, as described in Hot-adding an NS224 drive shelf.

Option 2: Add an I/O module in a system with no open slots

You must remove one or more existing NIC or storage modules in your system in order to install one or more I/O modules into your fully-populated system.

  1. If you are:

    Replacing a…​ Then…​

    NIC I/O module with the same the same number of ports

    The LIFs will automatically migrate when its controller module is shut down.

    NIC I/O module with fewer ports

    Permanently reassign the affected LIFs to a different home port. See Migrating a LIF for information about using System Manager to permanently move the LIFs.

    NIC I/O module with a storage I/O module

    Use System Manager to permanently migrate the LIFs to different home ports, as described in Migrating a LIF.

  2. Shut down controller A:

    1. Disable automatic giveback: storage failover modify -node local -auto-giveback false

    2. Take over the target controller: storage failover takeover -ofnode target_node_name

      The console connection shows that the controller drops to the LOADER prompt when the take over is complete.

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

  4. Unplug any cabling on the target I/O module.

  5. Remove the target I/O module from the chassis:

    1. Depress the lettered and numbered cam button.

      The cam button moves away from the chassis.

    2. Rotate the cam latch down until it is in a horizontal position.

      The I/O module disengages from the chassis and moves about 1/2 inch out of the I/O slot.

    3. Remove the I/O module from the chassis by pulling on the pull tabs on the sides of the module face.

      Make sure that you keep track of which slot the I/O module was in.

  6. Install the I/O module into the target slot:

    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.

  7. Repeat the remove and install steps to replace additional modules for controller A.

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

  9. Reboot the controller from the LOADER prompt: bye

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

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

  12. If you added:

    If I/O module is a…​ Then…​

    NIC module in slots 3 or 7,

    Use the storage port modify -node *<node name> -port *<port name> -mode network command for each port.

    Install and cable your NS224 shelves, as described in Hot-adding an NS224 drive shelf.

  13. Repeat these steps for controller B.
