My Fellow Admins, I have a backup environment comprised of a single RHEL 5 Master server (which doubles as a media server) and a single dedicated media server, also running RHEL 5. These 2 servers are backing up a small environment of approximately 100 servers with a combined weekly backup volume of about 20 - 30 terabytes.
On each server, I only have 1 of the available 4 NICs configured. Each morning I come in and a handful of my larger boxes are still running and getting terrible throughput. I've looked at CPU, memory and other statistics on the box, and it doesn't look like I'm overloading my master and/or media server. I think it's simply a case of my 1 NIC per box is getting saturated during my backup window and each of my clients isn't getting a lot of throughput to whichever machine is backing it up. I have asked my network team to please run a second cable to the second NIC on each box. I've brought both NICs online. I have selected 1 solaris 10 client in my backup environment that I want to try and send all its backup traffic to the second interface on whichever box ends up backing it up and night. I've scanned through the NetBackup admin guide for Unix/Linux and I've browsed the knowledgebase on Symantec's website for ideas on how to do this. I've seend two or three ways to do it and I'm trying to figure out which one best suits what I'm trying to do. This first KB article I read is: http://seer.entsupport.symantec.com/docs/316357.htm which suggests going into Global attributes and setting "Use Specified Network Interface" on the client. My question is, I have two different interfaces I could potentially use: the 2nd NIC on my master or the second NIC on my media server. This box implies I can only put in one interface. Since it's a crap shoot which media server will get the task of backing the machine up, I'm not sure if this is the option for what I want to do. Then I found this article: http://seer.entsupport.symantec.com/docs/269879.htm Which talks about the REQUIRED_INTERFACE directive in the /usr/openv/volmgr/vm.conf file.But upon reading the technote, that doesn't sound quite like what I'm trying to do. Any ideas? - Heathe Kyle Yeakley _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
