Richard> Hi! I have a problem that I was hoping I could get some Richard> advice on. In particular, where to start looking...
Richard> I inherited a Rocks Cluster which I am trying to make Richard> semi-usable. There are 31 nodes in the cluster, so in order Richard> to create the cluster network, two Dell switches are used -- Richard> a PowerConnect 5224 and a PowerConnect 5324. The head node Richard> and most of the computer nodes are plugged into the 5224, and Richard> the rest are plugged into the 5324 which then is plugged into Richard> the 5224. The problem that I'm having is that the clients on Richard> the 5324 cannot be PXE booted properly. If I plug them into Richard> the 5224, let them boot and install, and then plug them back Richard> into the 5324, they work correctly, until the next time I Richard> need them to reboot (to add a package, or something). Richard> I assume there is some kind of packet that is not being Richard> properly forwarded by the 5324 (or not being allowed by the Richard> 5224). What I would like is to convince the two switches that Richard> they are really one big(ger) switch, so they don't block Richard> anything from going around. Unfortunately, I really don't Richard> know much about networking beyond the basics -- in Richard> particular, I don't know the terminology. Looking at the Richard> configurations of the switches, I see things like Richard> "spanning-tree", "bridging", "trunks", etc. Richard> What should I be looking at? I tried to Google various Richard> things, but I'm not convinced I even know where to start -- Richard> at least, nothing I've found seems to address my question, or Richard> at least make sense to me. Try checking that port-fast is/isn't turn on for the ports. We have a problem here with our DELL 5224s not working right with our Cisco 4507 running IOS showing the same symtoms. So far I haven't beaten on it enough to chase down the real config issue, mostly because I only kickstart once in a while and I don't run the switch and don't want to run the switch. Nate also has some good thoughts here, and more details too. Good luck.
