What kind of scheduling do you use? If you use prompted scheduling then it's the TSM server that will contact the client for backup not the other way around. As far as which ip the client will connect to if you leave the dns entry, it will connect to the ip address that the dns entry resolves too. I don't know what kind of tsm server you have but with windows, you can create a load balancing team with multiple adapters so you do not need to assign multiple address to each nic card. That is the ideal way of doing it. If you can't do load balancing on the server then I suggest a separate network for backups.
-----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] Behalf Of Tyree, David Sent: Thursday, April 06, 2006 3:51 PM To: ADSM-L@VM.MARIST.EDU Subject: DSM.OPT file I've got a question about the usage of the "TCPSERVERADDRESS" line in the dsm.opt file on the clients. 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?
