Instruction Manual

Configuring and Managing RAID 111
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 cannot replace a SED with a non-SED
if the virtual disk is secured.
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 is displayed 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 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
BGI to continue.
