Move Master to new server with new hostname

[dieder15]

My question is I need to move my Master Server to new hardware which will also have a new hostname.

I have 1 server that is the Master/Media Server and is running 6.0 MP4. I need to move this server to a new server with a new hostname. Are there any procedures or posts documented for this or has anyone successfully completed this before?

Thanks.

Have a look at appendix A in the Netbackup 6.0 Admin Guide vol 1, it shows how to move the EMM DB.

Though changing the hostname is not that simple as netbackup keeps a reference to the hostname of the media server for each fragment in the header file for each image in the NBU DB. You can change this reference using the bpimage -newserver <new-server> -id <media-id>, for each media used for backups.

Also NBU also keeps host references in the EMM for the servers that backed up using a certain piece of media. You can look at this using the nbemmcmd -listmedia -allrecords and this needs to be updated also. So that media will expire.

So if you can keep the original hostname you save yourself a LOT of trouble. If you need to move then take a hot or cold backup of the original and perform a recovery to the new host.

Thanks for information, I'm still hesitant on moving it to a server with a new name. I'm trying to see if it's possible to keep the same name or start net new and import images as required for restores etc.

It is possible, though VERY difficult, with 5.1. It is not possible with 6.0. The name is too embedded into the databases. It is one of the biggest pains and something thaqt should be continually brought up as an issue to Symantec.

I would recommend that you don't try it.

I have also been in an situation where I had to change the name of the master server (it was on 5.1 in I remember right)

To change the name of the masterserver isn't something I would advice anyone to do except if the MUST to it.
And if you MUST do it pay Veritas Consulting to do it for you.

There have been people talking about that changing the name of the master server will be something that will be put in a future release of NBU.

Some months ago I had to move my masterserver to a new Sun X4600 (I am running Windows on it) and after talks with Veritas Consulting we choose to keep the old name (that doesn't follow our naming standard)
