Foreign Configurations in Cable Pull and Disk Removal Scenarios
If one or more physical disks are removed from a configuration, by a cable
pull or physical disk removal, for example, the configuration on those disks is
considered a foreign configuration by the RAID controller.
Use the
Foreign Configuration Preview
screen to import or clear the
foreign configuration in each case.
The following scenarios can occur with cable pulls or physical disk removals.
If you want to import the foreign configuration 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 physical disks 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 disks.
Start a consistency check immediately after the rebuild is complete to ensure
data integrity for the virtual disks.
2. Scenario #2: If some of the physical disks 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 disks.
Start a consistency check immediately after the rebuild is complete to ensure
data integrity for the virtual disks.
3. Scenario #3: 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.
Import or clear the foreign configuration. If you select Import, all drives
that were pulled before the virtual disk became offline will be imported
and then automatically rebuilt. Automatic rebuilds will occur in redundant
virtual disks.
4. If the physical disks in a non-redundant virtual disk are removed, the
controller considers the drives to have foreign configurations. Import or
clear the foreign configuration. No rebuilds will occur after the import
operation because there is no redundant data to rebuild the drives with.
