Table 3.3 Configuration Utility Adapter Submenu
Option Description
Clear Configuration This option erases the current RAID configuration in the NVRAM.
FlexRAID PowerFail Use this option to enable the FlexRAID
®
PowerFail feature, which allows drive
reconstruction to continue when the system restarts after a power failure.
Fast Initialization Use this option to initialize the logical drive by writing zeros to the first sector of
the logical drive. The fast initialization completes in 3 seconds.
When this option is set to Disabled, a full initialization takes place on the entire
logical drive. On a larger array (over five drives), LSI recommends setting fast
initialization to Disabled, then initializing. Otherwise, the controller runs a
background consistency check within 5 minutes of reboot or RAID 5 creation.
Disk Spin up Timings Use this option to configure the timing for spinning up the hard disk drives. The
options are Automatic , 2 disks every 6 secs , 4 disks every 6 secs , and
6 disks every 6 secs .
Cache Flush Timings Use this option to set the cache flush interval to 2, 4, 6, 8, or 10 seconds.
Rebuild Rate Use this option to change the drive rebuild rate. The rebuild rate is the
percentage of system resources dedicated to rebuilding a failed drive. A rebuild
rate of 100 percent means the system is totally dedicated to rebuilding the failed
drive. The default is 30 percent.
