Hi
Check cdrom and mount point both should be empty :-)

Try with fuser to the mount point, or lsof to the device file

It can be:
1. Someone, or maybe yours, pwd is on /cdrom.
2. The /dev/dsk/c0t0d0 is already mounted somewhere else.
3. /cdrom is nfs mounted to other system while it was busy there.

None of the condition is matching.

Hi
Try to mount it to /mnt instead of /cdrom

mount /dev/dsk/c0t0d0 /mnt .

It the above is successfull. then remove /cdrom dir and recreate it

Hi,

Johnson :

>>bdf /cdrom --> output
>>fuser -c /cdrom --> output

I am wondering this output as per the question he is not able to mount the cdrom, in this case how you will do fuser /cdrom.

Sumeet: It might be the hardware issue, I think DVD ROM not able to read your disk. You can try this also clean your DVD ROM (Lense) it may works sometimes.

Hi,

Altough it doesnt seems to be a hardware issue, still sometimes cross-checking may help.

If possible try attaching the CDROM device to another server and see if it mounts.
