Can it be that the CDROM is mounted to another mountpoint?
Just type : mount | grep c1t2d0

Peter

fuser -c only works on the root directory of a file system. What you need to do is to check whether /cdrom is empty or not (ls -a /cdrom) and if it is do an fuser on the directory.

Other things to test:
fuser /dev/dsk/c1t2d0
fuser /dev/rdsk/c1t2d0
showmount -e (it might be exported but not yet mounted remotely. This will also result in this error.)

For testing purposes, create a new directory and try mounting your drive at that point.

Check that no pfs daemons are using the device:
ps -ef | grep pfs
