Though you got the answer, still you may try running diskinfo for the character device in doubt.

# diskinfo /dev/rdsk/c1t2d0
SCSI describe of /dev/rdsk/c1t2d0:
vendor: _NEC
product id: DVD+RW ND-2100AD
type: CD-ROM
size: 0 Kbytes
bytes per sector: 0

And look for type there.............

Now that you know the device file, a common 'trick' is to link the device file to something more memorable, it could save you 10 seconds when mounting a DVD :o)

ln -s /dev/dsk/c0t0d0 /dev/dsk/cdrom

You will then be able to mount a DVD with:

mount /dev/dsk/cdrom /cdrom
