Foreign Configurations in Cable Pull and Drive Removal Scenarios
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 dialog
to import or clear the foreign configuration in each case.
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
The operation cannot be reversed after it is started. Imported drives
display as Online in the MegaRAID Storage Manager window.
NOTE
When you create a new configuration, the MegaRAID Storage
Manager software shows only the unconfigured drives. Drives that
have existing configurations, including foreign configurations, do not
appear. To use drives with existing configurations, you must first clear
the configuration on those drives.
NOTE
If you want to import the foreign configuration in any of the following
scenarios, you must have all of the drives in the enclosure before you
perform the import operation.
NOTE
Start a consistency check immediately after the rebuild is complete to
ensure data integrity for the virtual drives. See
Check
for more information about checking data consistency.
