Scan Devices Option
When you select the Scan Devices option on the Main screen, the Intel
2 checks the physical and virtual drives for any changes of the drive status. The Intel
BIOS Console 2 displays the results of the scan in the physical and virtual drive descriptions.
Virtual Drives Screen
You can access the virtual drives screen by clicking on a virtual drive in the virtual drive list on
the main screen. The upper right section of the screen displays the virtual drives that currently
exist. The Virtual Drives screen provides options to:
68
•
Adapter BIOS: Determines whether the Option ROM is loaded.
•
Coercion Mode:
— None: No coercion of size.
— 128M: The software rounds the drive capacity down to the next 128 MB boundary
and then up to the nearest 10 MB until the coerced capacity is larger than the actual
drive size. It is then reduced by 10 MB.
— 1G: The software rounds the drive capacity down to the nearest 1 GB boundary and
then down by 1 MB. This corresponds to the terms most drive manufacturers use.
•
PDF Interval: The PDF interval is the predictive disk failure polling interval. This is the
time needed between disk polls to perform SMART polling.
•
Alarm Control: Disable the alarm to turn off the on-board speaker alarm.
•
Interrupt Throttle Count and Interrupt Throttle Time: Sets the interrupt throttle and
count times. This is the number of times that interrupts are coalesced and the amount of
time that firmware holds an interrupt before passing it to the host software. Set values
lower for better performance—be aware that latency is impacted by these settings.
•
Cache Flush Interval: This sets the cache flush interval. Valid settings are 2, 4, 6, 8, or
10 seconds.
•
Spinup Drive Count: This setting controls the number of drives that spin up at one
time.
•
Spinup Delay: After the RAID controller completes its initialization process, the initial
delay value defines the number of seconds before the first disk interrogation request is
issued to the array or disk group. Do not change this value.
•
Stop On Error: Stops system POST if any error is detected.
•
NCQ: Enables NCQ (Native Command Queuing) to optimize physical drive
performance and life.
•
Stop CC On Error: Stops Consistency Check if any error is detected.
•
Schedule CC: Schedules a Consistency Check.
•
Maintain PD Fail History: Enables tracking of bad PDs across reboot.
•
Initialize the virtual drives: The Slow Initialize option initializes the selected virtual
drive by writing zeroes to the entire volume. You should initialize each new virtual drive
that you configure.
Warning: Initializing a virtual drive deletes all information on the physical drives that
compose the virtual drive.
