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.

• The physical disks in a non-redundant virtual disk are removed.

The following constraints apply to the physical disks that are considered for import:

• The disk state of a physical disk can change from the time the foreign configuration is scanned to

when the actual import occurs. The foreign import occurs only on disks that are in the Unconfigured

Good state.

• Disks in the failed or offline state cannot be imported.

• The firmware does not allow you to import more than eight foreign configurations.

Perform the following procedures on the Foreign Configuration View screen to manage foreign

configurations in each specific case:

1. If all or some of the physical disks in a configuration are removed and reinserted, the controller

considers the disks to have foreign configurations. Perform the following steps:

a. Select Foreign Configuration View to display the foreign configuration information on the

Foreign Configuration View screen.

b. Press <F2> to display the options (Import, Clear).

NOTE: You must have all the disks in the system before you perform the import operation.

c. Select Import to import the foreign configuration to the controller or select Clear to delete the

foreign configuration(s) from the re-inserted disk(s).

In the Preview Configuration Data window, the status of a physical disk that needs to be rebuilt is

displayed as Rebuild.

NOTE: When you import a foreign configuration, the dedicated hot spares in the

configuration are imported as dedicated hot spares on two conditions — the associated

virtual disk is already present or the associated virtual disk is also imported along with the

configuration.

NOTE: Start a consistency check immediately after the rebuild is complete to ensure data

integrity for the virtual disks. For more information about checking data consistency, see the

topic Checking Data Consistency.

2. If all the physical disks in a virtual disk are removed at different times and re-inserted, the controller

considers the disks to have foreign configurations. Perform the following steps:

a. Select Foreign Configuration View to display the complete virtual disk, across different foreign

configurations and allow foreign configurations to be imported.

b. Press <F2> to display the options Import and Clear.

NOTE: You must have all the drives in the system before you perform the import operation.

c. Select Import to merge the foreign configurations with the existing configuration on the

controller or

Clear to delete the foreign configuration(s) from the re-inserted disk(s).

If you select Import, all drives that were pulled before the virtual disk became offline are

imported, and then automatically rebuilt.
