Re: [Veritas-bu] Media Server with multiple NICS]
Travis, Very good point! I was neglecting the network routing aspect. So if I create multiple SERVER= entries for my Media Servers with the appropriate hostnames (resolving back to the correct IP addresses) and put these lines in the relevant bp.conf files on the clients then the routing should take care of the rest?

Re: [Veritas-bu] Media Server with multiple NICS]
Exactly. We have SERVER entries for each of our media servers nics in or clients bp.conf so then we just route traffic OUT whichever nic we want on the media server and the client connects back and sends data to that nic. I'm not sure why you would want to have different storage units on the same media server for its different virtual hostnames. We write data to the same tape stu no matter which nic it rides in on.

Re: [Veritas-bu] Media Server with multiple NICS
This might be late in the topic but its my 2 cents... We have an enviornment where we have 4 media servers and 1 master server. Each server has at least 3 different nics/networks. We use one network for administrative purposes, another for backup purposes, and a third for production purposes. This setup is the same for all our clients as well. All servers (clients included) use their hosts file (windows unix) to specify which interface they have to talk on when it comes to doing backups/restores. DNS is out the window when it comes to our enterprise backup network. On Mon, Mar 3, 2008 at 6:34 AM, [EMAIL PROTECTED] wrote: Greetings Paul, OK, I guess I mis-interpreted your question, apoligies.

Re: [Veritas-bu] Media Server with multiple NICS]
You should be able to achieve this without anu configuration changes to NB itself. We use multiple nics and you just have to make sure the routing is correct. When bpcd on the media server connects to the client the client will then connect back to that same ip (assuming that ip is allowed in the bp.conf on the client). So make sure you route traffic out the proper interface and the client will send data back through that interface. You do not need multiple storage units. The storage unit is not tied to the interface the data came in on. Hope this helps. Travis - Original message - Yes, appears so, I'd like to know what you find. Regards Carl ...

Re: [Veritas-bu] Media Server with multiple NICS
Paul, Each NIC on the media server should have a separate IP. Assign each IP a name in dns Ensure that the static routes are set up correctly between the media server and the clients. This part is critical. This means if you run a traceroute from teh media server to the client it is sending the packet out the correct NIC on the media server to the correct NIC on the client. Set up a unique storage unit for each IP assigned to a NIC servicing clients on the media server. As a suggestion, use the DNS name assigned to that IP. You will need at least one policy per storage unit. Consider naming the policy based on the underlying the storage unit. Group the appropriate clients in the appropriate policies. Other pertinent settings are MPX, multipstreaming, and vault duplication. Here are questions for you; what type of storage units are you using? Are you going directly to tape, VTL or to a DSU first? What kind of DSU? Do you use SSO? Do you use vault? Do the clients have multiple NICs as well? __ Jonathan Marianu (mah ree ah' nu) ATT Storage Planning and Design Architect (360) 597-6896 Work Hours 0800-1800 PST M-F Manager: Jim Taylor (dt3249) (678) 893-3170 ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
Re: [Veritas-bu] Media Server with multiple NICS
Is anyone out there using Media Servers with multiple NICs on separate networks? I am trying to understand how to force clients to use specific interfaces on the Media Server when sending backup data or receiving restore data. Do I need to create multiple storage unit and Media Server entries to be able to target the clients through the policy? Or am I on the wrong track altogether? Wrong track, I believe. It's more a network thing than a NetBackup thing. See below. Everything I have to say here stems from one oddball (to me, then) requirement where my master had to backup a distant environment; said environment had an internal, non-routable backup network for the clients and media server. Master, remote media server and remote clients are all on a public network. Master has no access to the backup network. This isn't your setup, but the mechanisms should all be applicable. [...] My clients won't have multiple NICS only the Media Server because its receiving input from multiple subnets so the use of REQUIRED_INTERFACE on the client won't help. I basically want to send certain clients to certain interfaces/addresses on the Media Server. Doesn't the Master tell the client where to send it's backup data via the policy information i.e. storage unit/device host? Doesn't the media server tell the client? R_I turned out not to be the magic bullet I expected. As explained to me, it's operation is if hostA is initiating a conversation with hostB and has multiple routes to hostB, use this one. (Side conversation was: fix your routing; R_I is [only] there for when your routing is broken.) Part of that education was something I should have known in the first place: a conversation continues on the interface where it was initiated. Control that, and you're golden. In my pathological case above, what worked for me was controlling hostname resolution: - master resolves media and client by their public interface - media resolves master by its public IF and client by the backup IF - client resolves master by its public IF and media by the backup IF That wasn't pretty (client resolving to 1.2.3.4 from the master and 10.5.6.7 from the media, for instance) but it worked. IIRC, so did client-initiated actions, auto-discovery streaming mode, agents and options. In a normal backup scenario nbjm starts the backup using bpcd to start bpbrm on the Media Server. The bpbrm process in turn starts bptm which then uses bpcd to start bpbkar on the client. Its the interaction between bpbkar on the client and bptm on the Media Server that I am trying to control but in my case the Media Server is a different host from the Master.

Re: [Veritas-bu] Media Server with multiple NICS
There is a paremeter you can put in the bp.conf file that is supposed to force the data through a NIC I think it is called REQUIRED_INTERFACE = ip address or dns name I have always found that netbackup like to use DNS for all name resolution., so I would not use the ip address. This is documented for UNIX systems, I don't know if windows has a similar option. I am not sure if it works with master initiated backups. Probably what you would need to do is assign different host name to your alternate interface and change the client name in the policy on the master to refer to the DNS name you have given for that NIC. In that case you probably do not need the REQUIRED_INTERFACE entry in the bp,.conf file. Hopefully this is not too confusing.

Re: [Veritas-bu] Media Server with multiple NICS
We're running two subnets here, one for data and one for backup communication. When we upgraded to 6.0 I thoroughly tested this and found the following. DNS/HOSTS defines the IP address that the server will try to contact (via bpcd) Your server will then follow whatever routing it has internally to find that IP address. The REQUIRED_INTERFACE (Unix / bp.conf) or Use specified network interface (Windows, Client Properties) will bypass routing and force a client to use that interface for backup communication / traffic. To figure out which interface your client will use, you really need to consider where backups initiate. My configuration: Public / Routable Fontend for client communication with whatever Private / Non-routable Backend for backup traffic. Master/Medias have 1 IP on the Public and 1 IP on the NBU Backend Some clients have 1 IP on the Public and 1 IP on the NBU Backend Some client have 1 IP on the Public (only) All servers' primary IPS are public and we've got DNS pointing to that. example: master.intersil.com (frontend / public IP) so do the clients - client1.intersil.com. We've also given the backend / netbackup network interfaces DNS (Host/A) entires - master.be.intersil.com / client.be.intersil.com. You can hardcode your master server's jobs to use the FQDN (client1.be.intersil.com) which will cause the master to use the backend. Alternately, I've configured my dns lookup to use be.intersil.com before intersil.com Therefore: master scheduled backup of client1 -- master queries dns for client1 -- finds client1.be.intersil.com -- IP is on the backend -- master uses the backend interface to contact the client since other clients don't have backend IPs (and thus no backend IP DNS Entry.) it goes something like: master scheduled backup of client2 -- master queries dns for client2 -- does not find client2.be.intersil.com -- finds client2.intersil.com -- IP is on the frontend -- master uses the frontend interface to contact the client (per routing rules.) The caveat here is in your client configuration. Your client1.be.intersil.com (above) is going to receive a backup request from master.be.intersil.com - which it won't allow. You've got to make sure that Before I got here we used hosts files to accomplish the same feat (except no be.intersil.com extentions.) The backup servers just thought client1's IP was the backend IP. Let me know if that helps you out. I've got similar things worked out for DMZ scenarios (internal/external) and even a backup environment with split routing which is intresting. -Jonathan From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Friday, February 29, 2008 3:24 PM To: Esson, Paul Cc: veritas-bu@mailman.eng.auburn.edu; [EMAIL PROTECTED] Subject: Re: [Veritas-bu] Media Server with multiple NICS There is a paremeter you can put in the bp.conf file that is supposed to force the data through a NIC I think it is called REQUIRED_INTERFACE = ip address or dns name I have always found that netbackup like to use DNS for all name resolution., so I would not use the ip address.
