To manage foreign configurations:1. If all or some of the physical disks in a configuration are removed and reinserted, the controllerconsiders the disks to have foreign configurations. Perform the following steps:a. Select Foreign Config to display the foreign configuration information on the Foreign Configscreen.b. Press 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 theforeign 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 isdisplayed as Rebuild.NOTE: When you import a foreign configuration, the dedicated hot spares in theconfiguration are imported as dedicated hot spares on two conditions — the associatedvirtual disk is already present or the associated virtual disk is also imported along with theconfiguration.NOTE: Start a consistency check immediately after the rebuild is complete to ensure dataintegrity for the virtual disks. For more information about checking data consistency, seeChecking Data Consistency .2. If all the physical disks in a virtual disk are removed at different times and re-inserted, the controllerconsiders the disks to have foreign configurations. Perform the following steps:a. Select Foreign Configuration View to display the complete virtual disk, across different foreignconfigurations and allow foreign configurations to be imported.b. Press 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 thecontroller 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 areimported, and then automatically rebuilt.NOTE: Start a consistency check immediately after the rebuild is complete to ensure dataintegrity for the virtual disks. For more information about checking data consistency, seeChecking Data Consistency .3. If the physical disks in a non-redundant virtual disk are removed, the controller considers the disks tohave foreign configurations. Perform the following steps:a. Select Foreign Configuration View to display the complete foreign configuration information.b. Press to display the options Import and Clear.c. Select Import to import the foreign configurations to the virtual disk or Clear to delete theforeign configuration(s) from the re-inserted disk(s).No rebuilds occur after the import operation because there is no redundant data to rebuild thedisks with.Break MirrorA Break Mirror is performed only on RAID 1 arrays. It provides a way to 'split' the mirror and spin-downone of the hard disks, which can then be imported into the configuration of a different PERC H730Pcontroller. This can be a useful way to:48
