12.3 Clearing the Controller Configuration

You can clear the configuration of a controller to accommodate changes in your storage space. For example, you may want to clear a controller if you upgraded your hardware or if you plan to move the controller to another machine. Clearing the configuration destroys the controller meta-data, including array and logical device information and so on. Once you clear the controller configuration, your online data is no longer accessible.
CAUTION: When you clear a controller configuration, you lose all data stored on that controller. Be sure you no longer need the data on the controller before proceeding.
Note: Clear configuration option resets the user configuration. Once the NVMe Config Update Remaining Count reaches 0, a system reboot is required to perform Clear Configuration operation.

To clear the controller configuration:

  1. In the Enterprise View, select a system, then select a controller on that system.
  2. On the ribbon, in the Controller group, click Manage Configuration.
    The Manage Configuration wizard opens.
  3. Select Clear Configuration, then click Next.
  4. Review the Summary information, then click Finish.
