Netvault WebUI Manage devices slots browser media space available column displaying as N/A
Selecting the media and click Explore media will still show the space available for each tape.
1. If tracking media using space available is needed, there is a workaround to generate a report of space available of all media in the tape library.
In Netvault WebUI, Click "View reports" | Select the "Library Contents" report | Click "Run&View"
You should be able to see the correct space left/available in each media from the report.
This issue is fixed in Netvault Backup 11.1
