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

[Tingli]

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.

bdf /cdrom --> output

fuser -c /cdrom --> output

# fuser -c /cdrom
/cdrom: fuser: could not find file system mounted at /cdrom.

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.

Your drive is not able to read the media........that's why coming device busy and not able to mount.
