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The rem_drv command informs the system that the device driver device_driver is no longer valid.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.
