unmount: 0506-349 Cannot unmount /dev/cd0: The requested resource is busy

We have a problem to unmount the cdrom ? Only a reboot will help.

/home/root [root@tst] # > unmount /cdrom
unmount: 0506-349 Cannot unmount /dev/cd0: The requested resource is busy.
/home/root [root@tst] # > fuser -u /dev/cd0
/dev/cd0:
/home/root [root@tst] # > fuser -k /dev/cd0
/dev/cd0:
/home/root [root@tst] # > unmount /cdrom
unmount: 0506-349 Cannot unmount /dev/cd0: The requested resource is busy.
/home/root [root@tst] # >

Our operating system is AIX 5.1 ML 03

Thank you for the help,

We know what the problem is !!!!!!. We are using CA-agent for scheduling. This product (ENF) gives problemes.
When we stop CA we could umount filesystems.
Here is some wording which may be helpful in approaching CA. The problem is in their kernel extension relating to their intercept of system calls. There driver should appear as /etc/drivers/enf/ca*. I
don't know if this may be helpful for you to search their database, but I would think the most direct route would be to approach CA technicalsupport directly, explain the problem, and enlist their help in identifying the right packaging surrounding a fix--- much as we're the
experts for AIX fixes, I would expect CA to provide clear direction for your customer.

With kind regards,
