Managing modes

RAID mode or HBA mode

The controller operates in either RAID mode or HBA mode, but not both. Smart Array Controllers allowing HBA mode can be configured to run in RAID mode. In HBA mode, all physical drives are presented directly to the operating system and the hardware RAID engine is disabled.

When HBA mode is enabled, RAID mode is disabled. To enable RAID mode, disable HBA mode.
