To manage foreign configurations:

If all or some of the physical disks in a configuration are removed and reinserted, the controller
considers the disks to have foreign configurations. Perform the following steps:
a. Select

Foreign Config

to display the foreign configuration information on the

Foreign Config

screen.

b. Press <F2> to display the options (

Import

Clear

NOTE: You must have all the disks in the system before you perform the import operation.

c. Select

Import

to import the foreign configuration to the controller or select

Clear

to delete the

foreign configuration(s) from the re-inserted disk(s).
In the

Preview Configuration Data

window, the status of a physical disk that needs to be rebuilt is

displayed as

Rebuild

NOTE: When you import a foreign configuration, the dedicated hot spares in the
configuration are imported as dedicated hot spares on two conditions — the associated
virtual disk is already present or the associated virtual disk is also imported along with the
configuration.

NOTE: Start a consistency check immediately after the rebuild is complete to ensure data
integrity for the virtual disks. For more information about checking data consistency, see

Checking Data Consistency

If all the physical disks in a virtual disk are removed at different times and re-inserted, the controller

considers the disks to have foreign configurations. Perform the following steps:
a. Select

Foreign Configuration View

to display the complete virtual disk, across different foreign

configurations and allow foreign configurations to be imported.

b. Press <F2> to display the options

Import

and

Clear

NOTE: You must have all the drives in the system before you perform the import operation.

c. Select

Import

to merge the foreign configurations with the existing configuration on the

controller or

Clear

to delete the foreign configuration(s) from the re-inserted disk(s).

If you select

Import

, all drives that were removed before the virtual disk became offline are

imported, and then automatically rebuilt.

NOTE: Start a consistency check immediately after the rebuild is complete to ensure data
integrity for the virtual disks. For more information about checking data consistency, see

Checking Data Consistency

If the physical disks in a non-redundant virtual disk are removed, the controller considers the disks to

have foreign configurations. Perform the following steps:
a. Select

Foreign Configuration View

to display the complete foreign configuration information.

b. Press <F2> to display the options

Import

and

Clear

c. Select

Import

to import the foreign configurations to the virtual disk or

Clear

to delete the

foreign configuration(s) from the re-inserted disk(s).
No rebuilds occur after the import operation because there is no redundant data to rebuild the
disks with.

Break Mirror

is performed only on RAID 1 arrays. It provides a way to 'split' the mirror and spin-down

one of the hard disks, which can then be imported into the configuration of a different PERC H730P
controller. This can be a useful way to:
