REM_DRV(8) Maintenance Procedures REM_DRV(8)


rem_drv - remove a device driver from the system


rem_drv [-b basedir] device_driver


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device_driver is no longer valid.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
configuration files.

If rem_drv has been executed, the next time the system is rebooted it
automatically performs a reconfiguration boot (see kernel(8)).


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 referenced
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(7).


Remove dangling device attribute nodes bound to the driver being
removed. This causes any device ownership or permissions
customizations 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
customizations might not be desired.


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

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.
