Use the add_drv(1M) command to install the driver in the system. If the driver installs successfully,add_drv runs devfsadm(1M) to create the logical names in the /dev directory.
# add_drv xx |
In this case, the device identifies itself as xx. The device special files have default ownership and permissions (0600 root sys). The add_drv command also allows additional names for the device (aliases) to be specified. See the add_drv(1M) man page for information on adding aliases and setting file permissions explicitly.
Do not use the add_drv command to install a STREAMS module. See the STREAMS Programming Guide for details.
If the driver creates minor nodes that do not represent terminal devices such as disks, tapes, or ports, you can modify /etc/devlink.tab to cause devfsadm to create logical device names in /dev. Alternatively, logical names can be created by a program that is run at driver installation time.
