Andre,
if you have a CD in the drive, the command
rmmount -l
will give you the path you are looking for. An example on snv_124:
bash-3.2# cdrw -l
Looking for CD devices...
Node Connected Device Device type
----------------------+--------------------------------+-----------------
cdrom0 | TOSHIBA DVDW/HD TS-L802A AC03 | CD Reader/Writer
bash-3.2# rmmount -l
/dev/dsk/c1t0d0s2 cdrom,cdrom0,cd,cd0,sr,sr0,OpenSolaris,/media/OpenSolaris
you can disable the volume manager using the command
svcadm disable rmvolmgr
