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 congurations with the existing conguration on the controller or Clear to delete the foreign
conguration(s) from the re-inserted disk(s).
If you select Import, all drives that were removed before the virtual disk became oine 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 .
3 If the physical disks in a non-redundant virtual disk are removed, the controller considers the disks to have foreign congurations.
Perform the following steps:
a Select Foreign Conguration View to display the complete foreign conguration information.
b Press <F2> to display the options Import and Clear.
c Select Import to import the foreign congurations to the virtual disk or Clear to delete the foreign conguration(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
A 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 conguration of a dierent PERC 9 series controller. This can be a useful way to:
• Create a disk image that can be imported and booted on a dierent system.
• Assist in software or conguration testing, where half of the mirror can be removed to ensure conguration consistency.
NOTE
: The Break Mirror operation is not available within the booted operating system environment. It is only available in
the BIOS Conguration Utility (<Ctrl> <R>) utility and the UEFI RAID conguration utility.
Break mirror in BIOS conguration utility
The RAID 1 virtual disk that you wish to split must be in an optimal state, and it cannot be running any other background tasks.
To use the Break Mirror feature, from the BIOS Conguration Utility Ctrl R, perform the following steps:
1 During boot up, press Ctrl R when prompted by the BIOS screen. If there is more than one controller in the system, choose the
controller.
The VD Mgmt screen is displayed by default.
2 Highlight the appropriate Disk Group
3 Press F2 to display the available actions.
4 Choose Break Mirror and press <Enter>.
A dialog box is displayed describing the operation and asking if you are sure you want to perform the operation.
5 Select Yes to continue.
The exported disk (exporting conguration) spins down and the hard drive status LED starts ashing to identify which drive must be
removed.
The remaining disk (exporting conguration) is in a degraded state until the missing member is replaced or rebuilt.
If there are any Global or Dedicated Hot Spare assigned, which fullls the rebuild requirements for the degraded RAID 1 disk, a rebuild
starts automatically. If there is no hot spare assigned, then an hot spare that meets all the requirements for the virtual disk must be
assigned before the rebuild starts.
