thanks again Ian, <br><br>the key is what you have said "Think of them as "recieve only""<br><br>Now all is clear like water ;-)<br><br>thank you very much for your help<br><br>Greetings<br><br>ESG<br><br> <div class="gmail_quote">2009/5/5 Ian Hayes <span dir="ltr"><<a href="mailto:cthulhucalling@gmail.com">cthulhucalling@gmail.com</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="im">On Tue, May 5, 2009 at 12:54 PM, ESGLinux <span dir="ltr"><<a href="mailto:esggrupos@gmail.com" target="_blank">esggrupos@gmail.com</a>></span> wrote:<br></div><div class="gmail_quote"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="im"> Hello, <br><br>Thanks for your answer...<br><br></div><div class="gmail_quote"><div class="im">2009/5/5 Ian Hayes <span dir="ltr"><<a href="mailto:cthulhucalling@gmail.com" target="_blank">cthulhucalling@gmail.com</a>></span></div> <div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><br><br><div class="im">All cluster management communication in this cluster is via eth1. I specified host1-management and host2-management as the hostnames in the cluster config to partition off cluster traffic from the interfaces that are actually doing the VIP work. The nodes provide a virtual IP on eth0, and a script service, with the daemon bound to the VIP. For the iLOs and eth1, you could either plug them into a switch on their own non-trunked VLAN, or you can connect eth1 of host1 to the iLO of host 2, and eth1 of host2 to the iLO of host1. Both eth1 and iLOs don't need a gateway since they're on the same subnet.<br> </div></blockquote></div><div class="im"><div><br>If I have understand, if I use a dedicated switch, I must to connect IP2, IP3, IP5 and IP6 to the same switche and IP1 and IP4 to the service switch, isn´t it?</div></div> </div></blockquote><div><br> If you're using a dedicated switch for cluster management, yes. Assuming that IP1 and 4 are your public facing interfaces that will be holding the service. You can use 2 and 5 for cluster management and fencing via IP3 and 6.<br> <br>Or you can use crossover cables IP2 to IP6, and IP5 to IP3, but you will have to run your cluster management over eth0, on the same interface that you have your services bound to. Your choice.<br><br>But you can't reach the iLO interfaces using the other iLOs. Think of them as "recieve only". It's up to one of the hosts to establish a connection to them and issue commands.<br> </div></div> <br>--<br> Linux-cluster mailing list<br> <a href="mailto:Linux-cluster@redhat.com">Linux-cluster@redhat.com</a><br> <a href="https://www.redhat.com/mailman/listinfo/linux-cluster" target="_blank">https://www.redhat.com/mailman/listinfo/linux-cluster</a><br></blockquote></div><br>
