rem_drv(1M) System Administration Commands rem_drv(1M)NAMErem_drv - remove a device driver from the system
SYNOPSISrem_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device_driver is no longer valid.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.
