Table: Modifiable service group items

Item	Notes
System list	You can add nodes to or remove them from the cluster. If you want to remove a node, make sure that it is not the active one.
Volumes	You can add or remove volumes. If you remove a volume on which an Enterprise Vault service is configured, the service ceases to be highly available and is not monitored.
Virtual IP	You can change the virtual IP address if the service group is offline. You cannot change the virtual server name, which is fixed when you create the service group.

You can modify an Enterprise Vault service group in several ways, including the Enterprise Vault Cluster Setup Wizard, Cluster Manager (both Java Console and Web Console), and the command line. The following steps describe how to modify the service group with the Enterprise Vault Cluster Setup Wizard.

Before you proceed, note the following:

You must run the wizard from a node on which the service group is online. You can then use the wizard to add resources to or remove them from the configuration.
You must take the service group partially offline to change the resource attributes. However, the MountV and VMDg resources for the service group should be online on the node where you run the wizard and offline on all other nodes. Mount all the volumes created to store Storage service data (vault stores), registry replication information, Shopping service data, Indexing data and MSMQ data.
If you want to modify the system list or volumes, the service group must be online.

To modify an existing VCS service group

Start the Enterprise Vault Cluster Setup Wizard.
Review the information in the Welcome page, and then click Next to display the Wizard Options page.
Click Modify service group, and then click Next.
Follow the instructions to modify the service group.

Note that if you add a system to an online service group, any resources with local attributes may briefly have a status of UNKNOWN. After you add the new node to the group, run the Enterprise Vault Configuration Wizard on this node to configure the Enterprise Vault services for it.
