3. Press the down-arrow key and highlight the desired physical disk you want to replace. Press <F2> to
expand the list of allowed operations on the disk.
4. Select Replace.
5. Select Start.
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 unconfigured disk without a foreign

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.
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 Configuration 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.
