Foreign Configurations in Cable Pull and Drive Removal Scenarios
If one or more drives are removed from a conguration, by a cable pull or
drive removal, for example, the conguration on those drives is considered a
foreign conguration by the RAID controller.
Use the Foreign Conguration Preview screen to import or clear the
foreign conguration in each case.
The following scenarios can occur with cable pulls or physical drive removals.
If you want to import the foreign conguration in any of the following scenarios,
you should have all the drives in the enclosure before you perform the import
operation.
1. Scenario #1: If all of the drives in a conguration are removed
and re-inserted, the controller considers the drives to have foreign
congurations.
Import or clear the foreign conguration. If you select Import, automatic
rebuilds will occur in redundant virtual drives.
Start a consistency check immediately after the rebuild is complete to ensure
data integrity for the virtual drives.
2. Select a conguration or All Congurations.
