  Deleting devices from I/O Database? 
 The Question is:
 
How do I delete a virtual unit (DSA)?
- without rebooting!
Case:
$ Mount DSA99 /shad=$4$somediske: label
$ Dismount DSA99
Then I'm still stuck with DSA99 with no members, and I want to get rid of it.
 
 The Answer is:
 
  There is no supported way to delete any OpenVMS I/O database device
  entry from the OpenVMS I/O database.  (Other than performing a system
  reboot, of course.)
 
  The I/O data structures consume several hundred bytes of storage, and
  are otherwise harmless.
