p These controllers can support RAID levels 0, 1, 1E, 3, 5, 6, and JBOD.
p .Nm supports management of the controllers via the .Xr bio 4 interface and the .Xr bioctl 8 utility.
p Please note, however, that to use some features that require special privileges, such as creating/removing hot-spares, pass-through disks or RAID volumes will require to have the .Em password disable in the firmware; otherwise a .Em Permission denied error will be reported by .Xr bioctl 8 .
p The .Nm driver will also report to the kernel log buffer any error that might appear when handling firmware commands, such as used by the .Xr bioctl 8 utility.
