11.5.12.1 Foreign Configurations
in Cable Pull and Drive Removal
Scenarios
6. Repeat the import process for any remaining drives.
Because locked drive can use different security key, you must verify whether there
are any remaining drives to imported.
NOTE: When you create a new configuration, MSM shows only the unconfigured drives.
Drives that have existing configurations, including foreign configurations, will not
appear. To use drives with existing configurations, you must first clear the configuration
on those drives.
If one or more drives are removed from a configuration, by a cable pull or drive
removal, for example, the configuration on those drives is considered a foreign
configuration by the RAID controller.
The following scenarios can occur with cable pulls or drive removals. Use the Foreign
Configuration Preview screen to import or clear the foreign configuration in each
case.
NOTE: If you want to import the foreign configuration in any of the following scenarios,
you should have all of the drives in the enclosure before you perform the import
operation.
 Scenario #1: If all of the drives in a configuration are removed and re-inserted, the
controller considers the drives to have foreign configurations.
Import or clear the foreign configuration. If you select Import, automatic rebuilds
will occur in redundant virtual drives.
NOTE: Start a consistency check immediately after the rebuild is complete to ensure
data integrity for the virtual drives.
See Section 10.2, Running a Consistency Check
consistency.
 Scenario #2: If some of the drives in a configuration are removed and re-inserted,
the controller considers the drives to have foreign configurations.
Import or clear the foreign configuration. If you select Import, automatic rebuilds
will occur in redundant virtual drives.
NOTE: Start a consistency check immediately after the rebuild is complete to ensure
data integrity for the virtual drives.
See Section 10.2, Running a Consistency Check
consistency.
 Scenario #3: If all of the drives in a virtual drive are removed, but at different times,
and re-inserted, the controller considers the drives to have foreign configurations.
