Tips
LSI Software RAID Configuration Utility can specify the foreground initialization
(FGI) and the background initialization priority (BGI Rate).
Universal RAID Utility cannot specify BGI Rate.
Universal RAID Utility cannot specify the initialization priority for LSI Embedded
MegaRAID. No parameter for specifying the initialization priority is provided on
the RAID Viewer properties.
