94 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:
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 "Checking Data Consistency" on page 91.
