What are the steps to add a disk to a Sun Solaris host online (no reboot of the host)?

A.
Drvconfig, disks

B.
Drvconfig, format, label

C.
Drvconfig, disks, devlinks

D.
Vi sd.conf, touch /reconfigure, init 6

Explanation:
{From a SUN OS man page:} devlinks creates symbolic links from the /dev directory tree to the actual blockand
character-special device nodes under the /devices directory tree. The links are created according to specifications found in the table-file (by default etc/devlink.tab). devlinks is called each time the system is reconfiguration- booted, and can only be run after drvconfig(1M) is run, since drvconfig(1M) builds the kernel data structures and the /devices tree.
