Importing or clearing foreign configurations using the
foreign configuration view screen
Prerequisites
About this task
If one or more physical disks are removed from a configuration, the configuration on those disks is considered a foreign configuration by
the RAID controller.
You can use the Foreign Config screen to view information about the foreign configuration, such as disk groups, virtual disks, physical
disks, space allocation, and hot spares. The foreign configuration data is displayed in the same format as configurations on the VD Mgmt
screen. You can use the VD Mgmt screen to view the foreign configuration before importing. After you view the foreign configuration,
you can either clear or import to the RAID controller.
