REM_DRV(1M)							   REM_DRV(1M)

NAME
       rem_drv - remove a device driver from the system

SYNOPSIS
       rem_drv [-b basedir] device_driver

DESCRIPTION
       The   rem_drv  command  informs	the  system  that  the	device	driver
       device_driver  is  no  longer  valid.  If  possible,  rem_drv   unloads
       device_driver  from memory. rem_drv also updates the system driver con‐
       figuration files.

       If rem_drv has been executed, the next time the system is  rebooted  it
       automatically performs a reconfiguration boot (see kernel(1M)).

OPTIONS
       The following options are supported:

       -b basedir

	   Sets the path to the root directory of the diskless client. Used on
	   the server to execute rem_drv for a client. The client machine must
	   be rebooted to unload the driver.

	   Note -

	     The  root	file system of any non-global zones must not be refer‐
	     enced with the -b option. Doing so might damage the global zone's
	     file  system,  might  compromise the security of the global zone,
	     and might damage the non-global zone's file system. See zones(5).

       -C

	   Remove dangling device attribute nodes bound to  the	 driver	 being
	   removed. This causes any device ownership or permissions customiza‐
	   tions made to any node not to  be preserved if the driver is	 added
	   back.  Recommended  for  use when reprovisioning a machine from one
	   configuration or use to  another  where  past  administrative  cus‐
	   tomizations might not be desired.

EXAMPLES
       Example 1 Removing the sd Driver

       The following example removes the sd driver from use:

	 example% rem_drv sd

       Example 2 Removing a Diskless Client

       The following example removes the driver from the sun1 diskless client.
       The driver is not uninstalled or unloaded until the client  machine  is
       rebooted.

	 example% rem_drv -b /export/root/sun1 sd

       Note  the caveat on the use of the -b option in the description of that
       option, above.
