Adding a node to a single-node cluster


Adding a node to a single-node cluster
Prev	Adding a node to a single-node cluster	Next

All nodes in the new cluster must run the same version of VCS. The example procedure refers to the existing single-node VCS node as Node A. The node that is to join Node A to form a multiple-node cluster is Node B.

Table: Tasks to add a node to a single-node cluster specifies the activities that you need to perform to add nodes to a single-node cluster.

Task	Reference
Set up Node B to be compatible with Node A.	See Setting up a node to join the single-node cluster.
Add Ethernet cards for private heartbeat network for Node B. If necessary, add Ethernet cards for private heartbeat network for Node A. Make the Ethernet cable connections between the two nodes.	See Installing and configuring Ethernet cards for private network.
Connect both nodes to shared storage.	See Configuring the shared storage.
Bring up VCS on Node A. Edit the configuration file.	See Bringing up the existing node.
If necessary, install VCS on Node B and add a license key. Make sure Node B is running the same version of VCS as the version on Node A.	See Installing the VCS software manually when adding a node to a single node cluster.
Edit the configuration files on Node B.	See About the VCS configuration files.
Start LLT and GAB on Node B.	See Starting LLT and GAB.
Start LLT and GAB on Node A. Copy UUID from Node A to Node B. Restart VCS on Node A. Modify service groups for two nodes.	See Reconfiguring VCS on the existing node.
Start VCS on Node B. Verify the two-node cluster.	See Verifying configuration on both nodes.
