I recently had to change the server name that Netbackup 9.0 was running on and now I can't connect to the robot device. Is there a way to change the master server name and the server name that the robot connects to?
I guess you mean NetBackup (there is no v9.0 yet, maybe in a few years).
Anyway, Symantec doesn't support changing the name of the master server. If you do, they won't support you. I did it once in v4.5, but in a very small environment. Never tried in v5.x, and I wouldn't dare attempt it with v6.0.
I noticed that the license keys specified a host. I was worried about uninstalling and reinstalling and not being able to install the license keys onto a server with a different name. I called Symantec and spoke with their Licensing group. They verified that I would be able to uninstall the version and reinstall again with no troubles because it was version 6.0. Later versions are dependent on the host that the key is activated on. I saved the netbackup\db\class directory with all the policies. We will import media into Netbackup as we use it. It appears to be working fine now. We will know for sure after our nightly backups.
