Dear Sir, magma-plugins was installed but still probelm. Before that i will explain how the installtion was carried out. 1.REdhat has shipped the Redhat Cluster Suite 4 for Itanium ,IA64 and Ia 32 cd. The Itanium Cd was Inserted and made to run in autmode.But it gives error of cman-kernel and dlm-kernel is required. 2.Through command line installed both the rpm using #rpm -ivh cam-kernel-* --nodeps #rpm -ivh dlm-kernel-* --nodeps. 3.Again the autorun was executed and installed all the rpm which shows in selection menu.(Same process was carried out in other node also). 4.Executed the command system-config-cluster and configured Cluster name and node name.Sabed the filed. 5.Copied /etc/cluster/cluster.conf to other node. 6.Execcuted #service ccsd start .# service cman failed ,# service rgmanger start All shows failed. Pls help what is the mistake in this process. Regds B.Ganesh -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
