To change device file status, do the following:
1. Log in as root on the machine.
2. Issue the cm setdevok command to change the status of device files on specific filesets:
# cm setdevok [-path {filename | directory_name}...] [-state {on | off}]
The -path option specifies a file or directory from each fileset for which device file status is to be changed. Omit this option to change the status for the fileset containing the current working directory.
The -state on option causes device files from the indicated filesets to be honored; the -state off option prevents device files from the indicated filesets from being honored. If this option is omitted, device files from the specified filesets are honored.
