Configuring and Managing RAID
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 function 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 displays a message if you want to
stop BGI in progress. An alert message displays if 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 displays: The virtual disk is
undergoing a background initialization process. Would
you like to stop the operation and proceed with the
check> instead?
Click Yes to stop the BGI and start the requested operation or No to allow
BGI to continue.
Performing a Manual Rebuild of an Individual Physical Disk
