RDAC is a multipathing software, (like vxdmp or powerpath). Other symptom includes finding the module
loaded.
bash-2.03# modinfo | grep rd
42 103231bf 8f2 235 1 rdnexus (RDAC Pseudo Controller Driver)
43 1032391b 19fb4 236 1 rdriver (Solaris RDAC Driver)
well, you can find out how the paths are shown by issuing:
bash-2.03# SMdevices
