MegaRAID BIOS Configuration Utility
Configuration Utility Format Menu
Select the Format option from the Configuration Utility Management Menu to low-
level format one or more physical drives.
WARNING: Formatting a hard drive destroys all data on the drive.
Since most SCSI disk drives are low-level formatted at the factory, this step is usually
not necessary. You must format a disk only if:
•
The disk drive was not low-level formatted at the factory, or
•
An excessive number of media errors have been detected on the disk drive.
You do not have to choose Format to erase existing information on your SCSI disks,
such as a system partition. That information is erased when you initialize the logical
drive(s).
Configuration Utility Rebuild Menu
Select the Rebuild option from the Configuration Utility Management Menu to rebuild
one or more failed hard drives.
Configuration Utility Check Consistency Menu
Choose this option to verify the redundancy data in logical drives that use RAID levels
1 or 5.
When you choose Check Consistency, the parameters of the existing logical drives on
the current controller and a selection menu listing the logical drives by number appear.
If a discrepancy is found, it is automatically corrected, assuming always that the data is
correct. However, if the failure is a read error on a data drive, the bad data block is
reassigned with the generated data. Perform the following steps to perform a check
consistency.
1. Press the arrow keys to choose the desired logical drives.
2 Press the spacebar to select or deselect a drive for consistency checking.
3. Press <F2> to select or deselect all the logical drives.
4. Press <F10> to begin the consistency check. A progress indicator for each selected
logical drive displays.
5. When the consistency check is finished, press any key to clear the progress display
and press <Esc> to display the Management Menu.
