cannot eject cdrom in pve3.4

[laowolf]

when run eject command in pve3.4, got "eject: unable to eject, last error: Inappropriate ioctl for device".
I have to reboot the server to eject the cdrom. but once I closed the cdrom and run eject again, I got same error message again.
how to solve this problem?

use cdrom only for install proxmox..
for installation vm use iso

The point is when I want to use cdrom, I have to reboot the whole proxmox server. It's painful, and same hardware is out of this problem in pve3.3.
