.Sh DESCRIPTION
|
|
.Nm
|
|
allows a user or system administrator to issue commands to and otherwise
|
|
control devices which reside on standard IDE and ATA controllers. It is
|
|
used by specifying
|
|
a device to manipulate, the command to perform, and any arguments
|
|
the command may require.
|
|
.Sh DEVICE COMMANDS
|
|
The following commands may be used on IDE and ATA devices. Note
|
|
that not all devices support all commands.
|
|
.Pp
|
|
.Cm identify
|
|
.Pp
|
|
Identify the specified device, displaying the device's vendor, product,
|
|
revision strings, and the device's capabilities.
|
|
.Pp
|
|
.Cm idle
|
|
.Pp
|
|
Place the specified device into Idle mode. This mode may consume less
|
|
power than Active mode.
|
|
.Pp
|
|
.Cm standby
|
|
.Pp
|
|
Place the specified device into Standby mode. This mode will consume
|
|
less power than Idle mode.
|
|
.Pp
|
|
.Cm sleep
|
|
.Pp
|
|
Place the specified device into Sleep mode. This mode will consume
|
|
less power than Standby mode, but requires a device reset to resume
|
|
operation. Typically the
|
|
.Xr wd 4
|
|
driver performs this reset automatically, but this should still be
|
|
used with caution.
|
|
.Pp
|
|
.Cm setidle
|
|
.Ar idle-timer
|
|
.Pp
|
|
Places the specified device into Idle mode, and sets the Idle timer
|
|
to
|
|
.Ar idle-timer
|
|
seconds. A value of 0 will disable the Idle timer.
|
|
.Pp
|
|
.Cm setstandby
|
|
.Ar standby-timer
|
|
.Pp
|
|
Places the specified device into Standby mode, and sets the Standby timer
|
|
to
|
|
.Ar standby-timer
|
|
seconds. A value of 0 will disable the Standby timer.
|
|
.Pp
|
|
.Cm checkpower
|
|
.Pp
|
|
Will print out if the device is in Active, Idle, or Standby power
|
|
management mode.
|
|

|
|

|
|
command is rather ugly.
