This has nothing to do with the LD device. It's a standard behavior of VMS.
"Opened file" means open right now. Not "have been opened sometimes in 
tne past", nor "installed". It means it's currently open by a process. 
An installed file is an installed file, which is something else.
You must remove files from being installed before you are allowed to 
dismount a device. If a file is open on the device, VMS can either 
complain, or else mark the device for dismount, which will be completed 
when all files have been closed. I don't remember which way VMS actually 
do it.
But what was shown by the original post is completely natural, and to be 
expected if usage matches.
