.Sh DESCRIPTION
RAID device drivers which support management functionality can
register their services with the
.Xr bio 4
driver.
.Nm bioctl
then can be used to maintain RAID volumes.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl a Ar alarm-function

.It Ar enable
Enable the alarm on the RAID controller.
.It Ar get

.It Ar silence | Ar quiet
Silence the alarm if it is currently beeping.
.El
.Pp
The
.Ar alarm-function
may be specified as given above,
or by the first letter only
(e.g. -a e).
.It Fl b Ar channel:target[.lun]
Instruct the device at
.Ar channel:target[.lun]
to start blinking, if there is
.Xr ses 4
or
.Xr safte 4
support in the enclosure.
.It Fl C Ar flag[,flag,...]
Pass flags when doing operations with
.Nm .
May be one of:
.Pp
.Bl -tag -width disable -compact
.It Ar force
Force the operation, e.g. to force creation of volumes
with unclean data in the metatdata areas.
.It Ar noauto
Ignore this RAID volume upon reboot.
.El
.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 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
Where necessary, produce "human-readable" output.
Use unit suffixes: Byte, Kilobyte, Megabyte,
Gigabyte, Terabyte, Petabyte, Exabyte in order to reduce the number of
digits to four or less.
.It Fl i
Enumerate the selected RAID devices.
.It Fl l Ar special[,special,...]
Use
.Ar special
device list to create within the
.Xr softraid 4
framework.
Requires
.Fl c .
.It Fl q
Show vendor, product, revision, and serial number for the given disk.
.It Fl u Ar channel:target[.lun]
Instruct the device at
.Ar channel:target[.lun]
to cease blinking, if there is
.Xr ses 4
or
.Xr safte 4
support in the enclosure.
.It Fl v
Be more verbose in output.
.It Ar device
Select a drive by name (e.g. sd0) or a RAID controller by name (e.g. ami0).
For operations which will be performed against
.Xr ses 4
or
.Xr safte 4
enclosures, it is also possible to directly specify the enclosure name
(e.g. safte0).
.El
.Sh EXAMPLES
The following command, executed from the command line, would configure
the device softraid0 with 4 special devices
(/dev/sd2e, /dev/sd3e, /dev/sd4e, /dev/sd5e) and
a raid level of 1:
.Bd -literal -offset 3n
# bioctl -c 1 -l /dev/sd2e,/dev/sd3e,/dev/sd4e,/dev/sd5e softraid0
