media server drives failing on boot - reinstall questions

OK, so bptestbpcd connects successfully to media server on port 1556.

The GUI is probably using a different port number - 13782 or 13724?

Is anything logged in bpcd when the GUI connection fails?

About services not starting - my problem is with this one:

> NetBackup Volume Manager
> NetBackup Volume Manager -- NOT STARTED

This is why you cannot add devices. Please double-check license keys installed on this media server. 
If you do not have capacity license, you need Enterprise Server license as well as Library Based Tape Drive license.

If you have correct licenses installed, please add VERBOSE entry in ...\volmgr\vm.conf and try again to stop/start services. 
If Volume Manager still does not start, please check Event Viewer System and Application logs.
