My question is this, based on hardware addresses my lan4 on each node will change to either lan1 or lan 2. As such I need to recompile the cluster (lan4 is my heartbeat). Can I leave one node running while I redo the other. It will cause a lan mismatch, but I don't know if it will result in a failure or an ugly warning Tue, 29 Mar 2005 15:15:46 GMT https://community.hpe.com/t5/operating-system-hp-ux/reconfiguring-cluster/m-p/4893287#M700513 3M OS Support Team 2005-03-29T15:15:46Z https://community.hpe.com/t5/operating-system-hp-ux/reconfiguring-cluster/m-p/4893288#M700514 You will have to bring the nodes down in order to make the network changes....<BR /><BR /><A href="http://docs.hp.com/en/B3936-90079/ch07s04.html?btnNext=next%A0%BB" target="_blank">http://docs.hp.com/en/B3936-90079/ch07s04.html?btnNext=next%A0%BB</A><BR /><BR />Rgds...Geoff Tue, 29 Mar 2005 15:20:34 GMT https://community.hpe.com/t5/operating-system-hp-ux/reconfiguring-cluster/m-p/4893288#M700514 Geoff Wild 2005-03-29T15:20:34Z https://community.hpe.com/t5/operating-system-hp-ux/reconfiguring-cluster/m-p/4893289#M700515 Question answered Tue, 29 Mar 2005 15:24:05 GMT https://community.hpe.com/t5/operating-system-hp-ux/reconfiguring-cluster/m-p/4893289#M700515 3M OS Support Team 2005-03-29T15:24:05Z
