The Consistency Check runs and checks the redundancy data in the virtual disks.

7.After you start the Consistency Check, press <Esc> to display the previous menu if needed.

Importing Or Clearing Foreign Configurations Using The VD Mgmt Menu

When a foreign configuration exists, the BIOS screen displays the message Foreign configuration(s) found on adapter. In addition, a foreign configuration is displayed on the right side of the Ctrl Mgmt screen.

You can use the VD Mgmt menu to import the existing configuration to the RAID controller or clear the existing configuration. In addition, you can view the foreign configuration from the Foreign View tab without importing the configuration.

NOTE: The controller does not allow an import of configurations that results in more than 64 virtual disks.

NOTE: To import a secured foreign configuration, see the topic Security Key And RAID Management.

Perform the following steps to import or clear foreign configurations:

1.During bootup, press <Ctrl> <R> when prompted by the BIOS screen. The VD Mgmt screen is displayed by default.

2.On the VD Mgmt screen, highlight the Controller #.

3.Press <F2> to display the available actions.

4.Navigate to the Foreign Config option and press the right arrow key to display the available actions: Import and Clear.

NOTE: Ensure that your virtual disk has all the physical disks by verifying that there are no physical disks marked as Missing in the foreign view page and that all the disks appear as expected before importing them.

5.Select Import to import the foreign configuration or Clear to delete the foreign configuration and then press <Enter>.

If you import the configuration, the VD Mgmt screen displays detailed configuration information. It includes information about the disk groups, virtual disks, physical disks, space allocation, and hot spares.

Importing Or Clearing Foreign Configurations Using The Foreign Configuration View Screen

NOTE: To import a secured foreign configuration, see the topic Security Key And RAID Management.

If one or more physical disks are removed from a configuration, the configuration on those disks is considered a foreign configuration by the RAID controller.

You can use the Foreign Configuration View screen to view information about the foreign configuration, such as disk groups, virtual disks, physical disks, space allocation, and hot spares. The foreign configuration data is displayed in the same format as configurations on the VD Mgmt screen. You can use the VD Mgmt screen to view the foreign configuration before importing. After you view the foreign configuration, you can either clear or import to the RAID controller.

NOTE: Before you import the foreign configuration, review the configuration on the screen to ensure that it is the end result that you require.

You can use the Foreign Configuration View screen to manage foreign configurations in the following cases:

•All the physical disks in a configuration are removed and re-inserted.

•Some of the physical disks in a configuration are removed and re-inserted.

•All the physical disks in a virtual disk are removed, but at different times, and then re-inserted.
