.Sh DESCRIPTION
|
|
.Nm
|
|
is a control program that provides the user access and control to the
|
|
.Fx
|
|
.Xr ata 4
|
|
subsystem.
|
|
.Pp
|
|
.Nm
|
|
can cause severe system crashes and loss of data if used improperly, please
|
|
exercise caution when using this command!
|
|
.Pp
|
|
The
|
|
.Ar channel
|
|
argument is the number of the ATA channel on which to operate.
|
|
The following commands are supported:
|
|
.Bl -tag -width "rebuild"
|
|
.It Ic attach
|
|
Attach an ATA
|
|
.Ar channel ,
|
|
devices on the channel are probed and attached as
|
|
is done on boot.
|
|
.It Ic detach
|
|
Detach an ATA
|
|
.Ar channel ,
|
|
devices on the channel are removed from the kernel,
|
|
and all outstanding transfers etc. are returned back to the system marked
|
|
as failed.
|
|
.It Ic reinit
|
|
Reinitialize an ATA
|
|
.Ar channel .
|
|
Both devices on the channel are reset and
|
|
initialized to the parameters the ATA driver has stored internally.
|
|
Devices that has gone bad and no longer responds to the probe, or devices
|
|
that has physically been removed are removed from the kernel.
|
|
Likewise are devices that show up during a reset, probed and attached.
|
|
.It Ic create
|
|
Create a
|
|
.Ar type
|
|
ATA RAID.
|
|
The type can be
|
|
.Cm RAID0
|
|
(stripe),
|
|
.Cm RAID1
|
|
(mirror),
|
|
.Cm RAID0+1
|
|
or
|
|
.Cm SPAN
|
|
(JBOD).
|
|
In case the RAID has a
|
|
.Cm RAID0
|
|
component,
|
|
the
|
|
.Ar interleave
|
|
must be specified in number of sectors.
|
|
The RAID will be created
|
|
of the individual disks named
|
|
.Bk -words
|
|
.Ar disk0 ... diskN .
|
|
.Ek
|
|
.Pp
|
|
Although the ATA driver allows for creating an ATA RAID on disks on any
|
|
controller, there are restrictions.
|
|
It is only possible to boot on
|
|
an array if it is either located on a
|
|
.Dq real
|
|
ATA RAID controller like
|
|
the Promise or Highpoint controllers, or if the RAID declared is of
|
|
.Cm RAID1
|
|
or
|
|
.Cm SPAN
|
|
type; in case of a
|
|
.Cm SPAN ,
|
|
the partition to boot must
|
|
reside on the first disk in the SPAN.
|
|
.It Ic delete
|
|
Delete a RAID array on a RAID capable ATA controller.
|
|
.It Ic rebuild
|
|
Rebuild a RAID1 array on a RAID capable ATA controller.
|
|
.It Ic status
|
|
Get the status of an ATA RAID.
|
|
.It Ic mode
|
|
Without the two mode arguments, the current transfer modes of both
|
|
devices are printed.
|
|
If the mode arguments are given, the ATA driver
|
|
is asked to change the transfer modes to those given.
|
|
The ATA driver
|
|
will reject modes that are not supported by the hardware.
|
|
Modes are given like
|
|
.Dq Li PIO3 ,
|
|
.Dq Li udma2 ,
|
|
.Dq Li udma100 ,
|
|
case does not matter.
|
|
If one of the devices mode should not be changed, use a nonexisting mode
|
|
as argument (i.e.\&
|
|
.Dq Li XXX ) ,
|
|
and the mode will remain unchanged.
|
|
.It Ic info
|
|
Show info about the attached devices on the
|
|
.Ar channel ,
|
|
the device name and manufacture/version strings are shown.
|
|
.It Ic cap
|
|
Show detailed info about the device on
|
|
.Ar channel device
|
|
where device is 0 for master and 1 for slave.
|
|
.It Ic enclosure
|
|
Show detailed info about the encolsure on
|
|
.Ar channel device
|
|
where device is 0 for master and 1 for slave.
|
|
Fan RPM speed, enclosure temperature, 5V and 12V levels are shown.
|
|
.It Ic list
|
|
Show info about all attached devices on all active controllers.
