NOTE If you disable drive security, you cannot create any new encrypted
virtual drives and the data on all encrypted unconfigured drives will be
erased. Disabling drive security does not affect the security or data of
foreign drives.
12.12.4 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 MegaRAID Storage Manager software to import the foreign configuration to the
RAID controller or to clear the foreign configuration so you can create a new configuration using these drives.
To import a foreign configuration, you must perform the following tasks:

Enable security to allow importation of locked foreign configurations. (You can import unsecured or unlocked
configurations when security is disabled.)

Run a scan for foreign configurations.

If a locked foreign configuration is present and security is enabled, enter the security key, and unlock the
configuration.

Import the foreign configuration.
In addition, 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 there are any
drives left, 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 MegaRAID Storage
Manager software shows only the unconfigured drives. Drives that
have existing configurations, including foreign configurations, do not
appear. To use drives with existing configurations, you must first clear
the configuration on those drives.
Perform the following steps to import or clear a configuration:
1. Enable drive security to allow importation of locked foreign drives. See Enabling Drive Security for the procedure.
2. After you create a security key, right-click the controller icon, and select Scan for Foreign Configuration .
If locked drives (security is enabled) exist, the Unlock Foreign Drives dialog appears.
3. Enter the security key to unlock the configuration.
The Foreign Configuration Detected dialog appears, as shown in the following figure.
