6 Press the down-arrow to highlight a replacement disk and then press the spacebar to select the disk.
7 Select OK to start the replacement.
NOTE: The replacement disk must be a hot spare or an uncongured disk without a foreign conguration. It must have
the same or greater capacity and should be of the same type as the disk it is replacing.
Restrictions and limitations
The following restrictions and limitations apply to the Replace Member operation:
• The Replace Member functions are restricted to one per array for RAID 0, RAID 1, and RAID 5, and two per array for RAID 6.
• The Replace Member function and rebuild cannot run simultaneously on a RAID 6 virtual disk. The rebuild operation has a higher
priority, and the Replace Member operation is aborted if a rebuild begins.
Stopping background initialization
Background initialization (BGI) is the automated operation in which parity is created and written. BGI does not run on RAID 0 virtual disks.
Under certain conditions, the BIOS Conguration Utility (<Ctrl> <R>) displays a message if you want to stop a BGI in progress. An alert
message is displayed if a BGI is in progress and you start any of the following actions:
• A Full Initialization on the virtual disk
• A Fast Initialization on the virtual disk
• A Consistency Check on the virtual disk
The following alert message is displayed:
The virtual disk is undergoing a background initialization process. Would you like to stop the
operation and proceed with the <full initialization/quick initialization/consistency check>
instead?
Click Yes to stop the BGI and start the requested operation or No to allow the BGI to continue.
Performing a manual rebuild of an individual physical disk
CAUTION
: If a physical disk is a member of a disk group that contains multiple virtual disks and one of the virtual disks is deleted
when a rebuild operation is in progress, the rebuild operation stops. You can then resume the rebuild operation manually using a
storage management application. To avoid interruption, ensure that none of the virtual disks are deleted until the rebuild is
complete.
Follow the procedures below to rebuild one failed physical disk manually:
1 Press <Ctrl> <N> to access the PD Mgmt screen.
A list of physical disks is displayed. The status of each disk is displayed under the heading State.
2 Press the down-arrow key to highlight a physical disk that is in failed state.
3 Press <F2> to display a menu of available actions.
The Rebuild option is highlighted at the top of the menu.
4 Press the right-arrow key to display the rebuild options and select Start.
5 After you start the rebuild, press <Esc> to display the previous menu.
NOTE
: You can also use the VD Mgmt screen to perform a manual rebuild. Use the arrow key to highlight a physical
disk, and press <F2>. In the menu that is displayed, select the Rebuild option.
