92 Configuring and Managing RAID
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 88.

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.
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 88.
3
If the physical disks in a non-redundant virtual disk are removed, the
controller considers the drives to have foreign configurations. Perform the
following steps:
a
Select
Foreign Configuration View to
display the complete foreign
configuration information.
b
Press <F2> to display the options
Import
and
Clear
.
c
Select
Import
to import the foreign configuration to the virtual disk or
Clear
to delete the foreign configuration(s) from the re-inserted
disk(s).
No rebuilds occur after the import operation because there is no
redundant data to rebuild the drives with.
