We use two card or one. We have both TSM names in the DNS tsm_primary and tsm_backup. We then use the name we want to use in the dsm.opt file. The backup is a private network we use just for backups. We do not route to or from this network. Thus we can be sure that a server is not going out the primary and then across a bridge or router to the backup network. If it wants to go out the primary looking for tsm_backup then it will fail and we can look at the routing tables to find out what to fix. If the system only has a primary connection then we use tsm_primary in its dsm.opt. This has worked great for us. When we move tsm to a newer machine we get it working and then just change the dns names and that night everybody goes to the new server.

Currently I have the IP address of the TSM server listed in the dsm.opt file on the clients. We will be implementing a new addressing scheme for all of our servers in a couple of months and that includes the TSM server itself. In our case the DNS name of the server happens to match the name of the TSM server instance. Since our TSM server only has one NIC and thus only one IP address I went ahead and changed the line to show the DNS name of the TSM server instead of the IP on a few of the clients. The DNS name of the TSM server will not be changing, only the IP address. I wasn't sure at the time if the TSM client would work with the DNS name instead but I since found in the TSM docs it would. And found that it actually did work just fine. The next issue is that we are thinking about adding another NIC in the TSM at some point in the future to help split the load on the network. At that point the TSM server will then have two IP's. Any clients that I want to have come into the TSM server on the second NIC would have to have the IP of the second NIC in its dsm.opt file. That part makes complete sense. But what about any clients that I have with the DNS name of the TSM server in the dsm.opt file instead of the IP address? Which NIC would they connect to? If I absolutely wanted to ensure that the clients came into the TSM server on the right NIC I would make sure I had the right IP listed in that clients options file. But what would happen if I left the DNS entry in the options file?
