This is not really a howto but more of a quick lookup on what commands to use to debug/troubleshoot.
So this is not lay out in any order what so ever. Just a bunch of random notes…. I hope this helps you the way it has helped me….. 
1. There are 2 directories where logs exist! 1st dir is /usr/openv/logs (Low level logs) and
2nd dir is /usr/openv/netbackup/logs (Here you will have to create the subdirectories in order
for logs to be created here) BEWARE these logs tend to get huge!
