Configuring and Managing RAID

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:

Select Foreign Configuration View to display the

foreign configuration information on the

Foreign Configuration

View screen.

Press to display the options (Import, Clear).

NOTE:

You must have all the disks in the system before you perform the

import operation.

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
