SUNWcsu
The rem_drv command informs the system that the device driver device_driver is no longer valid.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. Entries for the device in the /devices namespace are removed. rem_drv also updates the system driver configuration files.
If rem_drv has been executed, the next time the system is rebooted it will automatically perform a reconfiguration boot (see kernel(1M) ).
The next example removes the driver from the sun1 diskless client. The driver will not be uninstalled nor unloaded until the client machine is rebooted.
