Decomissioning/replacing media servers

Created: 19 Feb 2014 • Updated: 28 Feb 2014 | 4 comments
This issue has been solved. See solution.

My current environment consist of 8 media servers (4 at each site). Also an IBM tape library, DataDomain and NDMP hosts at each site.

The plan is to decomission 2 media servers from each site.

I'd like the remaining 4 media servers (2 per site) to take over the roles of the media servers being decomissioned.

I am aware of the nbdecommission utility, just not so sure about the actual steps for my type of environment.

Use the nbdecommission with new server switch and it will move the assigned medias & images to new servers automatically and will do the complete decom of old server

Is there a more efficient way of updating the server entries on the clients, than going one by one ?

Yes.
Once the Server entries on the master server is updated, you can syncronize Clients' entries with  add_media_server_on_clients command.

SYNOPSIS
add_media_server_on_clients
 
On UNIX and Linux systems, the directory path to this command is
/usr/openv/netbackup/bin/
On Windows systems, the directory path to this command is
<install_path>\NetBackup\bin\
 
DESCRIPTION
Run the add_media_server_on_clients command from a NetBackup server to
synchronize the server list from the server’s configuration with the server lists
on the known clients.
 
The add_media_server_on_clients command tries to connect to all configured
clients (clients that are listed in backup policies).
 
For each client to which it can connect, add_media_server_on_clients updates
the client’s configuration (if necessary) to include all the servers from the server’s
configuration.
