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 re-inserted, the controller
considers the drives 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
NOTE:
You must have all the drives in the enclosure 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).
Automatic rebuild occurs in redundant virtual disks if the VD transitions into DEGRADED before
going OFFLINE.
NOTE:
Start a consistency check immediately after the rebuild is complete to ensure data integrity for
the virtual disks. See "Checking Data Consistency" on page 66 for more information about checking data
consistency.
2 If all the physical disks in a virtual disk are removed, but at different times, and re-inserted, the
controller considers the drives 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
NOTE:
You must have all the drives in the enclosure 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 will be
imported, and then automatically rebuilt. Automatic rebuild occurs in redundant virtual disks if
the VD transitions into DEGRADED before going OFFLINE.
NOTE:
Start a consistency check immediately after the rebuild is complete to ensure data integrity for
the virtual disks. See "Checking Data Consistency" on page 66 for more information about checking data
consistency.
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
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 will occur after the import operation because there is no redundant data to rebuild the
drives with.
