Tips
•
LSI Software RAID Configuration Utility can set FGI Rate (Foreground Initialization
priority) and BGI Rate (Background Initialization Priority). But Universal RAID Utility
cannot set Background Initialization Priority.
•
Initialization priority cannot be set by Universal RAID Utility in LSI Embedded
MegaRAID. To set the initialization priority, use LSI Software RAID Configuration
Utility.
