Configuring two Enterprise Vault server nodes and a spare node in a VCS N+1 cluster

Figure: Three-node VCS cluster with two Enterprise Vault server nodes and a spare node illustrates a configuration in which there is a spare node in addition to the two nodes on which the Enterprise Vault servers are running.

You configure the service group for EVSERVER1 to run on both NODEA and NODEC, and the service group for EVSERVER2 to run on both NODEB and NODEC. EVSERVER1 and EVSERVER2 are both virtual computer names from the service group.

To configure two Enterprise Vault server nodes and a spare node in a VCS N+1 cluster

  1. Mount the volumes on the system where you will configure the Enterprise Vault service group.

  2. On either NODEA or NODEC, run the Enterprise Vault Cluster Setup wizard and create a service group called EVSERVER1 for these two nodes.

  3. On either NODEB or NODEC, run the Enterprise Vault Cluster Setup wizard and create a service group called EVSERVER2 for these two nodes.

  4. Take the actions described below on NODEA and NODEB, depending on whether you are performing a first-time installation of Enterprise Vault or upgrading an existing installation.

    Node

    New installation

    Upgrade installation

    NODEA

    Run the Enterprise Vault Configuration wizard. Choose to configure a new Enterprise Vault server with cluster group for EVSERVER1.

    Run the Convert to Cluster wizard. Choose to create the service resources in the EVSERVER1 service group.

    NODEB

    Run the Enterprise Vault Configuration wizard. Choose to configure a new Enterprise Vault server with cluster group for EVSERVER2.

    Run the Convert to Cluster wizard. Choose to create the service resources in the EVSERVER2 service group.

  5. On NODEC, run the Enterprise Vault Configuration wizard and choose to add this node as a failover node for an existing clustered server. Select either service group.

    When you bring the service groups online on NODEA and NODEB, Cluster Explorer may falsely indicate a problem with the GenericService resources (their icons in the left pane may have question marks). This is because VCS assumes that each resource is simultaneously online on two nodes. You can ignore this situation.
