The Solaris OS device driver architecture implicitly requires that all drivers support dynamic addition of a new device instance. Therefore all drivers should support DR attach.
After the DR attach operation, devfsadmd(1M) automatically invokes the devfsadm(1M) command to reconfigure I/O device tree. Please refer to section 2.3.3 "DR Administration Issues" for more details.
Device path names newly added are written to the /etc/path_to_inst file. The same path names are also added to the /devices hierarchy, and links are created in the /dev directory.
