rem_drv(1M) System Administration Commands 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The rem_drv command informs the system that the device driver device_driver is no longer valid.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 configuration 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 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(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 customizations 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.
