.Nm bioctl
|
|
.Ar device
|
|
.Ar command
|
|

|
|
.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 manage the RAID controller's properties.
|
|
.Sh COMMANDS
|
|
The following commands are supported:
|
|
.Bl -tag -width XXstrategyXXnameXX
|
|
.It Ic show Op Ar disks | volumes
|
|
Without any argument by default
|
|
.Nm
|
|
will show information about all volumes and the logical disks used
|
|
on them.
|
|
If
|
|
.Ar disks
|
|
is specified, only information about physical disks will be shown.
|
|
If
|
|
.Ar volumes
|
|
is specified, only information about the volumes will be shown.
|
|
.It Ic alarm Op Ar disable | enable | silence | test
|
|
Control the RAID card's alarm functionality, if supported.
|
|
By default if no argument is specified, its current state will be
|
|
shown.
|
|
Optionally the
|
|
.Ar disable ,
|
|
.Ar enable ,
|
|
.Ar silence ,
|
|
or
|
|
.Ar test
|
|
arguments may be specified to enable, disable, silence, or test
|
|
the RAID card's alarm.
|
|
.It Ic blink Ar start channel:target.lun | stop channel:target.lun
|
|
Instruct the device at
|
|
.Ar channel:target.lun
|
|
to start or cease blinking, if there's
|
|
.Xr ses 4
|
|
support in the enclosure.
|
|
.It Ic hotspare Ar add channel:target.lun | remove channel:target.lun
|
|
Create or remove a hot-spare drive at location
|
|
.Ar channel:target.lun .
|
|
.It Ic passthru Ar add DISKID channel:target.lun | remove Ar channel:target.lun
|
|
Create or remove a
|
|
.Ar pass-through
|
|
device.
|
|
The
|
|
.Ar DISKID
|
|
argument specifies the disk that will be used for the new device, and
|
|
it will be created at the location
|
|
.Ar channel:target.lun .
|
|
.Em NOTE :
|
|
Removing a pass-through device that has a mounted filesystem will
|
|
lead to undefined behaviour.
|
|
.It Ic check Ar start VOLID | stop VOLID
|
|
Start or stop consistency volume check in the volume with index
|
|
.Ar VOLID .
|
|
.Em NOTE :
|
|
Not many RAID controllers support this feature.
|
|
.It Ic create volume Ar VOLID DISKIDs Oo Ar SIZE Oc Ar STRIPE RAID_LEVEL channel:target.lun
|
|
Create a volume at index
|
|
.Ar VOLID .
|
|
The
|
|
.Ar DISKIDs
|
|
argument will specify the first and last disk, i.e.:
|
|
.Em 0-3
|
|
will use the disks 0, 1, 2, and 3.
|
|
The

|
.Ar SIZE
|
|
argument is optional and may be specified if not all available disk
|
|
space is wanted (also dependent of the
|
|
.Ar RAID_LEVEL ) .
|
|
The volume will have a stripe size defined in the
|
|
.Ar STRIPE
|
|
argument and it will be located at
|
|
.Ar channel:target.lun .
|
|
.It Ic remove volume Ar VOLID channel:target.lun
|
|
Remove a volume at index
|
|
.Ar VOLID
|
|
and located at
|
|
.Ar channel:target.lun .
|

Removing a RAID volume that has a mounted filesystem will lead to
|
|
undefined behaviour.

.Sh EXAMPLES
|
|
The following command, executed from the command line, shows the
|
|
status of the volumes and its logical disks on the RAID controller:
