Select this option to enable, disable, or silence the onboard alarm tone generator on the controller.
Use this option to force drives of varying capacities to the same size so they can be used in a drive
group. The coercion mode options are None, 128MB-way, and 1GB-way. The number you choose
depends on how much the drives from various vendors vary in their actual size.
Specifies the following options to set the BIOS boot mode:
 Stop on Error: shows the errors encountered during boot up and waits for your input. The
firmware does not proceed with the boot process till you take some action
 Bypass Error: Ignores errors and the firmware proceeds with boot.
Headless Continue on Error: the firmware may halt due to hardware faults. If the firmware

encounters no hardware faults, then the boot up continues.
 Headless Safe Mode: Boots the controller to run on safe mode.
Use this option to select the boot device from the list of virtual drives and JBODs.
Use this option to select the rebuild rate for drives connected to the selected controller. The rebuild
rate is the percentage of system resources dedicated to rebuilding a failed drive. The higher the
number, the more system resources that are devoted to a rebuild. The range of rebuild rate is
between 0 and 100 percent.
Use this option to select the amount of system resources dedicated to background initialization of
virtual drives connected to the selected controller. The range of background initialization (BGI) rate is
between 0 and 100 percent.
Use this option to select the amount of system resources dedicated to consistency checks of virtual
drives connected to the selected controller. The range of Consistency Check (CC) rate is between 0
and100 percent.
Use this option to select the amount of system resources dedicated to reconstruction of drives
connected to the selected controller. The range of Recon rate is between 0 and100 percent.
Use this option to select the rate for patrol reads for drives connected to the selected controller. The
patrol read rate is the percentage of system resources dedicated to running a patrol read. The range
of patrol read is between 0 to 100 percent.
Use this option to control the interval at which the contents of the onboard data cache are flushed.
The range of Cache Flush Interval is between 0 to100 seconds.
Use this option to control the interval (in seconds) between spinup of drives connected to this
controller.
The delay prevents a drain on the system's power supply that would occur if all drives spun up at the
same time. The range of Spinup Delay is between 0 to 255 seconds.
Use this option to control the interval at which the contents of the onboard data cache are flushed.
The range of Spinup Drive is between 0 to 255 seconds.
Use this option to maintain the history of all drive failures.
Use this option to enable or disable the BIOS for the selected controller.
If the boot device is on the selected controller, the BIOS must be enabled. Otherwise, the BIOS should
be disabled, or you might be unable to use a boot device elsewhere.
Use this option to stop a consistency check when the controller BIOS encounters an error.
Use this option to import automatically at boot time.
Use this option to load the default Ctrl-R Utility settings.
Use this option to change the link speed between the controller and the expander, or between a
controller and a drive that is directly connected to the controller.
Use this option to reduce the power consumption of drives that are not in use, by spinning down the
unconfigured good drives, hot spares and configured drives.
