Does anoyone here have some advice on the best way to switch from using a single NetBackup domain to multiple domains? With the advent of AIR and MSDPs, I want to take advantage of those technologies and eliminate the need at a disaster to promote a media server to master, then undo that after the disaster is over. I'm not looking to split my EMM server, I basically want the current master to retain the current EMM database and just create new EMM databases at the remote locations.
Current production config (all servers using NBU 7.5.0.5, all licensing is up to date):
- Main site - 1 Solaris master, 2 Linux media servers, 1 Solaris media server
- Remote site #1 - 1 Solaris media server
- Remote site #2 - 1 Solaris media server
Planned config:
- Main site - 1 Solaris master, 2 Linux media servers, 1 Solaris media server
- Remote site #1 - 1 Solaris master server, 1 Linux media server
- Remote site #2 - 1 Solaris master server, 1 Linux media server
I plan to promote the existing Solaris media servers at the two remote locations to master servers, so all of the masters will be Solaris and all media servers will be Linux. I have the MSDP set up for testing backups/restores/replications/duplications to tape/etc., at each location and everything is going smoothly.
I have concerns:
- Do I need to do anything special to wipe out the MSDPs at the remote locations before I reconfigure the media servers for the new domain?
- If I decomm the Solaris media server at a remote site from the existing domain, is it safe to retain the media server's name and uninstall the media server software, then re-install the software as a new master server? Or do I have to change the server name?
If anyone has performed a media server-> master server promotion as a permanent change (not just in a disaster situation), I would be interested in hearing about your experience.
Thanks!
