Controller #X Physical Drive #Y] and [ID], [Enclosure], and [Slot] (raidcmd).
Setting of Priority
WebBIOS displays and sets Rebuild Priority, Patrol Read Priority, and Consistency Check Priority of RAID Controller by
percentage. However, Universal RAID Utility uses three levels as High/Middle/Low for them.
NOTES:
„
WebBIOS can set BGI Rate (Background Initialize Priority). However, Universal RAID Utility
cannot set it.
„
Universal RAID Utility can set Initialization Priority. However, Internal RAID Controller does
not have the function of the setting of Initialization Priority. Therefore, Universal RAID Utility
does not display [Initialization Priority] in the [Options] tab of RAID Viewer. In addition, you
will fail if you change the Initialization Priority by raidcmd.
See the table below for correspondence.

Creating a RAID 6 Logical Drive
To create a Logical Drive of RAID 6 using the Universal RAID Utility, at least four Hard Disk Drives are required. If you want
to create a Logical Drive of RAID6 with three Hard Disk Drives, you need to use WebBIOS.
IMPORTANT: WebBIOS does not support the RAID6 logical drive having Stripe Size: 8KB
composed of three Hard Disk Drives.
