4.9.4 Importing or Clearing a Foreign Configuration
A foreign configuration is a RAID configuration that already exists on a replacement set of drives that you install in a
computer system. You can use the Ctrl-R Utility to import the foreign configuration to the RAID controller or to clear
the foreign configuration so that you can create a new configuration by using these drives.
To import a foreign configuration, you must perform the following tasks:

Enable security to permit importation of locked foreign configurations. You can import unsecured or unlocked
configurations when security is disabled.

If a locked foreign configuration is present and security is enabled, enter the security key, and unlock
the configuration.

Import the foreign configuration.
If one or more drives are removed from a configuration, by a cable pull or drive removal for example, the configuration
on those drives is considered a foreign configuration by the RAID controller.
Verify whether any drives are left to import because the locked drives can use different security keys. If any drives
remain, repeat the import process for the remaining drives. After all the drives are imported, there is no configuration
to import.
NOTE When you create a new configuration, the Ctrl-R Utility shows only the
unconfigured drives. Drives that have existing configurations,
including foreign configurations, do not appear. To use drives with
existing configurations, you first must clear the configuration on those
drives.
You can import or clear a foreign configuration from the VD Mgmt menu or from the Foreign View menu.
Perform the following steps to import or clear a foreign configuration from the VD Mgmt menu:
1. In the VD Mgmt screen, navigate to the controller, and press the F2 key.
2. Navigate to Foreign Config , and press Enter.
The foreign configuration options Import and Clear appear.
