Cannot mount cdrom drive - always "device busy"

[David Mores]

I am having a problem with the cdrom drive on a C3600 workstation. After a clean boot, attempting to mount a CD (mount /dev/dsk/c0d0t0 /cdrom) results in a "device busy" error message.

I have tried rebuilding the O/S via Ignite, swapping out the cd drive with a new unit, changing the mother board and cables with no success in resolving this problem. I must have missed something.

Looking for new ideas - Is there a hardware diagnostic that would help?

What does fuser show when run againt /cdrom??

[Uday_S_Ankolekar]

fuser -u /cdrom will show if any process is holding up your cdrom , kill that process and try remounting cdrom drive.

run fuser -cu /cdrom. or get lsof and run lsof /cdrom to see what processes are using the mount point.

Hi

#fuser -k /cdrom
#mount /dev/dsk/c0t0d0 /cdrom

if no help from fuser, look at mounting the drive somewhere else, an linking to cdrom.

May be you are using a wrong device file? Check the output of diskinfo too:

# diskinfo /dev/dsk/cxtydz

Try mounting on some other directory:
# mkdir test_cdrom
# mount /dev/dsk/cxtydz /test_cdrom
