I have this issue "Tapes are showing as 0 bytes after SP14 Upgrade". Then I have update to latest SP15 with Hotfix 7, but the issue does not resolved. I found out that in SP15 it does not has required HotFix that I need to install to resolve the issue which is HotFix-2301.
Is there any other way to install only HotFix-2301 in this current SP15. In older version we can select to install specific patches for an encountered issue.
