Installing the controller

After you install the replacement component into the controller module, you must reinstall the controller module into the system chassis and boot the operating system.

About this task

For HA pairs with two controller modules in the same chassis, the sequence in which you install the controller module is especially important because it attempts to reboot as soon as you completely seat it in the chassis.

Steps

  1. If you are not already grounded, properly ground yourself.
  2. If you have not already done so, replace the cover on the controller module.
  3. Align the end of the controller module with the opening in the chassis, and then gently push the controller module halfway into the system.
    Note: Do not completely insert the controller module in the chassis until instructed to do so.
  4. Complete the reinstallation of the controller module:
    The controller module begins to boot as soon as it is fully seated in the chassis.
    If your system is in... Then perform these steps...

    1. With the cam handle in the open position, firmly push the controller module in until it meets the midplane and is fully seated, and then close the cam handle to the locked position.
      Attention: Do not use excessive force when sliding the controller module into the chassis to avoid damaging the connectors.
    2. If you have not already done so, reinstall the cable management device.
    3. If you have not already done so, reconnect the cables to the controller module.
    4. Bind the cables to the cable management device with the hook and loop strap.

    3. If you have not already done so, reconnect the cables to the controller module.
    4. Bind the cables to the cable management device with the hook and loop strap.
    5. Reconnect the power cables to the power supplies and to the power sources, and then turn on the power to start the boot process.
  5. Return the node to normal operation:
    If your system is in... Issue this command from the partner's console...
    An HA pair storage failover giveback -ofnode impaired_node_name
    A two-node MetroCluster configuration Proceed to the next step.

    The MetroCluster healing and switchback procedures are done in the next task in the replacement process.

  6. If automatic giveback was disabled, reenable it: storage failover modify -node local -auto-giveback true
