I had NPM monitoring hard disk volumes on a server. This server was replaced with a new server and the new server's name and IP carried over from the old server. So, instead of removing the server from NPM, I left it thinking it would just continue monitoring. And as I thought, it did just that. Everything was working just fine until I noticed that one of my alerts was reporting incorrectly.
In the alert that I setup, I referenced a volumeID on that server, and thought that this Volume ID would be unchanged. I was wrong... What I found out is that NPM generated new Volume ID's for the new server and the old Volume ID's still existed. This actually makes sense as to why this is... I just didnt think of it at the time. So, the old Volume ID's still exist in the database, but are now irrelevant because they contain data from the old server. I would like to get rid of it.
So... does anyone know how to properly remove the irrelevant Volume ID's? I am comfortable with writing SQL queries if this is necessary. Any help is appreciated.
