physical disk contains a foreign configuration (virtual disk) by checking the physical disk state. If the
physical disk state is Foreign, then the physical disk contains all or some portion of a virtual disk. You can
clear or erase the virtual disk information from the newly attached physical disks.
The Clear Foreign Configuration operation permanently erases all data residing on the physical disks that
are added to the controller. If more than one foreign virtual disk is present, all the configurations are
erased. You may prefer to import the virtual disk rather than destroy the data. An initialization must be
performed to remove foreign data. If you have an incomplete foreign configuration which cannot be
imported, you can use the Clearing Foreign Configuration option to erase the foreign data on the
physical disks.

Resetting Controller Configuration
You can reset the configuration for a controller. This operation deletes virtual disk drives and unassigns all
hot spares on the controller. It does not erase any data other than removing the disks from the
configuration. Reset configuration also does not remove any foreign configurations. The real-time
support of this feature is available only in PERC 9.1 firmware. Reset configuration does not erase any data.
You may recreate the exact same configuration without an initialize operation which may result in the
data being recovered. You must have server control privilege.
NOTE: Resetting the controller configuration does not remove a foreign configuration. To remove a
foreign configuration, perform clear configuration operation.

2. From the Actions drop-down menu, select Reset Configuration for one or more controllers.
3. For each controller, from the Apply Operation Mode drop-down menu, select when you want to
