.It Fl c Ar raidlevel
Create a
.Xr softraid 4
device of level
.Ar raidlevel .
The device must begin with
.Dq softraid
followed by a number.
.It Fl D
Enable debug output.
.It Fl H Ar channel:target[.lun]
If the device at
.Ar channel:target[.lun]
is currently marked
.Dq Unused ,
promote it to being a
.Dq Hot Spare .
.It Fl h

digits to four or less.
.It Fl i
Enumerate the selected RAID devices.
.It Fl l Ar special[,special[,...]]
Use
.Ar special

enclosures, it is also possible to directly specify the enclosure name
(e.g. safte0).
