NAME

     dmctl -- manipulate device-mapper driver command

SYNOPSIS

     dmctl

DESCRIPTION

     dmctl works with the device-mapper kernel driver.	It can send and receive information and commands from the dm driver.

	   version    Print driver and lib version.
	   targets    List available kernel targets.
	   create     Create device with [dm device name].
	   ls	      List existing dm devices.
	   info       Get info about device with [dm device name].
	   rename     Rename device with [dm device name] to [dm device new name].
	   remove     Remove device with [dm device name].
	   resume     Resume IO on dm device [dm device name].
	   suspend    Suspend IO on dm device [dm device name].
	   deps       Print physical dependiences for dm device [dm device name].
	   reload     Switch active and passive tables for [dm device name].
	   status     Print status for device with [dm device name].
	   table      Print active table for device with [dm device name].

DEVCTL(8)						    BSD System Manager's Manual 						 DEVCTL(8)

NAME

     devctl -- device control utility

SYNOPSIS

     devctl attach device
     devctl detach [-f] device
     devctl disable [-f] device
     devctl enable device
     devctl suspend device
     devctl resume device
     devctl set driver [-f] device driver

DESCRIPTION

     The devctl utility adjusts the state of individual devices in the kernel's internal device hierarchy.  Each invocation of devctl consists of
     a single command followed by command-specific arguments.  Each command operates on a single device specified via the device argument.  The
     device may be specified either as the name of an existing device or as a bus-specific address.  More details on supported address formats can
     be found in devctl(3).

     The following commands are supported:

     attach device
	     Force the kernel to re-probe the device.  If a suitable driver is found, it is attached to the device.

     detach [-f] device
	     Detach the device from its current device driver.	If the -f flag is specified, the device driver will be detached even if the device
	     is busy.

     disable [-f] device
	     Disable a device.	If the device is currently attached to a device driver, the device driver will be detached from the device, but
	     the device will retain its current name.  If the -f flag is specified, the device driver will be detached even if the device is busy.

     enable device
	     Enable a device.  The device will probe and attach if a suitable device driver is found.  Note that this can re-enable a device dis-
	     abled at boot time via a loader tunable.

     suspend device
	     Suspend a device.	This may include placing the device in a reduced power state.

     resume device
	     Resume a suspended device to a fully working state.

     set driver [-f] device driver
	     Force the device to use a device driver named driver.  If the device is already attached to a device driver and the -f flag is speci-
	     fied, the device will be detached from its current device driver before it is attached to the new device driver.  If the device is
	     already attached to a device driver and the -f flag is not specified, the device will not be changed.
