Add an I/O module to your AFF A1K system to enhance network connectivity and expand your system's ability to handle data traffic.

You can add an I/O module to your AFF A1K 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 available 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 storage 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.

  • Make sure that all other components are functioning properly.

Add I/O module to an available slot

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

Steps

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

  2. Rotate the cable management tray down by pulling the buttons on the inside of the cable management tray and rotating it down.

  3. Remove the target slot blanking module from the carrier:

    1. Depress the cam latch on the blanking module in the target slot.

    2. Rotate the cam latch away from the module as far as it will go.

    3. Remove the module from the enclosure by hooking your finger into the cam lever opening and pulling the module out of the enclosure.

  4. Install the I/O module:

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

    2. Gently slide the module into the slot all the way into the enclosure, and then rotate the cam latch all the way up to lock the module in place.

  5. Cable the I/O module to the designated device.

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

  6. Rotate the cable management tray up to the closed position.

  7. From the LOADER prompt, reboot the node:

    bye

    Note This reinitializes the I/O module and other components and reboots the node.

  8. Give back the controller from the partner controller:

    storage failover giveback -ofnode target_node_name

  9. Repeat these steps for controller B.

  10. From the healthy node, restore automatic giveback if you disabled it:

    storage failover modify -node local -auto-giveback true

  11. If AutoSupport is enabled, restore automatic case creation:

    system node autosupport invoke -node * -type all -message MAINT=END
