Backup Central

I’ve built a simple networker environment, based on Sun Solaris and W2K
systems ( no cluster, thanks … ), using server, clients and storage nodes
definitions. The main customer requirement was to use only ( or mainly, at
its best ) a management network, instead of the production one.

Let me indicate the terminology, concerning production and management
network names:

Srv: server on the production network, and hostname
Srv_adm: server on the management network


Stn: storage node on the production network
Stn_adm: storage node on the management network

Cln_adm: client on the management network

I’ve installed NetWorker v7.2 server on a Solaris box, and the srv client
was installed automatically.

I’ve defined the Jukebox, with the server srv and the storage node stn
as storage nodes.

I had to configure stn ( also as client ) on the production network
because I’ve seen that, even if I tried to configure stn_adm, on the
storage node the nsrmmd daemons are always started with the “-s srv�
option and never with “-s srv_adm� option.

So I think that in this case mount/umount commands run on the production
network. What about media database informations??

Any client is always defined as cln_adm ( and cln is defined as its
alias ) ;I defined its “server network interface� as srv_adm and “storage
nodes� as stn_adm ( or srv_adm instead of nsrserverhost if the client has
to use the networker server as its storage node ).

I’ve added srv_adm as an alias of srv, and stn_adm as an alias of stn.

I only doubt about storage node configuration in the Jukebox and the fact
that the nsrmmd daemons seem to contact the server hostname and, for what
I know, there is no way to let them speak with srv_adm.

You are very close. You can make everything happen over the _adm network, you just have to do it initially that way in the jukebox setup.

When you build your jukebox start "jbconfig -s srv_adm"; when it asks jukebox prefix, give stn_adm:

On a storage node, the hostname is a prefix to the jukebox name.
Enter the hostname to use as a prefix? [stb] STN_ADM

Your device/jukebox for the storage node should be: rd=STN_ADM:/dev/rmt/Xcbn
The "rd=Server" is your communication path.

This will run your mount/umount commands over _adm network now. However, I did that previously and I seem to recall occasional problems (but I also had 1 master, 3 storage nodes)....YMMV.

PS. "( Ithink the only way is to change server hostname from srv to srv_adm âEUR¦ )" -- Don't do it, bad idea.

The client config for STN_ADM is a different item. If you configure the client as STN_ADM and treat it normally ("I defined its âEURoeserver network interfaceâEUR� as srv_adm and âEURoestorage nodesâEUR� as stn_adm"), it will run it's backups over the _adm network, but the client config has nothing to do with the jukebox communications.
---
We setup our Storage Nodes the way you have it now with STN_ADM as the client setup (STN_ADM has a Server Network Interface of Srv_adm and a Storage Node of Stn_adm) but we don't have a problem w/ the minimal mount/umount traffic on the production network.....it is miniscule compared to the level of traffic occurring on the _adm network. Again, YMMV. Thanks.
