170 Installing VCS on a single nodeAdding a node to a single-node clusterAdding a node to a single-node clusterTable 9-5 specifies the activities involved in adding nodes to a single-nodecluster. All nodes in the new cluster must run the same version of VCS. Theexample procedure refers to the existing single-node VCS node as Node A andthe node that is to join Node A to form a multiple-node cluster as Node B.Table 9-5TaskTasks to add a node to a single-node clusterReferenceSet up Node B to be compatible with Node “Setting up a node to join the single-nodeA cluster” on page 170■ Add ethernet cards for private “Installing and configuring Ethernet cardsheartbeat network for Node B for private network” on page 171■■If necessary, add ethernet cards forprivate heartbeat network for Node AMake the ethernet cable connectionsbetween the two nodesConnect both nodes to shared storage“Configuring the shared storage” onpage 172■ Bring up VCS on Node A “Bringing up the existing node” on page 172■Edit the configuration fileIf necessary, install VCS on Node B and add “Installing the VCS software manually” ona license key. page 172Make sure Node B is running the sameversion of VCS as the version on Node A.Edit the configuration files on Node B “See” on page 172Start LLT and GAB on Node B “Starting LLT and GAB” on page 175■ Start LLT and GAB on Node A “Reconfiguring VCS on the existing node”■ Restart VCS on Node A on page 176■Modify service groups for two nodes■ Start VCS on Node B “Verifying configuration on both nodes” on■ Verify the two-node cluster page 176Setting up a node to join the single-node clusterThe new node to join the existing single node running VCS must run the sameversion of operating system and patch level.
Installing VCS on a single nodeAdding a node to a single-node cluster171To set up a node to join the single-node cluster1 Do one of the following:■ If VCS is not currently running on Node B, proceed to step 2.■■■If the node you plan to add as Node B is currently part of an existingcluster, remove the node from the cluster. After removing the nodefrom the cluster, remove the VCS packages and configuration files.See “Removing a node from a cluster” on page 159.If the node you plan to add as Node B is also currently a single VCSnode, uninstall VCS.See “Removing VCS packages manually” on page 94.If you renamed the LLT and GAB startup files, remove them.See “Renaming the LLT and GAB startup files” on page 168.2 If necessary, install VxVM and VxFS.See “Installing VxVM, VxFS if necessary” on page 171.Installing VxVM, VxFS if necessaryIf VxVM with the cluster option or VxFS with the cluster option is installed onthe existing node in the cluster, then the same versions must also be installed onthe new node.Refer to the appropriate documentation for VxVM and VxFS to verify theversions of the installed products and make sure the same version is running onall nodes that are to use any shared storage.Installing and configuring Ethernet cards for private networkBoth nodes require ethernet cards (NICs) that enable the private network. If both Node A and Node B have ethernet cards installed, you can ignore this step.For high availability, two separate NICs on each node should be used, such that the failure of one NIC does not restrict heartbeating between the nodes.See “Setting up the private network” on page 32.To install and configure ethernet cards for private network1 Shut down VCS on Node A.# hastop -local2 Shut down the node to get to the OK prompt:# sync;sync;init 03 Install the ethernet card on Node A.4 Install the ethernet card on Node B.
