Configuring service groups
In order for VCS to be able to monitor and fail over an application in a cluster, the application must be included in a VCS service group.
A service group is a collection of resources working together to provide application services to clients. It can also relate to a file share that does not contain a specific application. A service group's resources fail over as a group to another cluster node when there is an application failure or server failure on the active node.
VCS provides multiple methods for creating a service group. If you have Microsoft Exchange Server or SQL Server as the application, VCS provides a wizard for each of these. There is also separate wizard for file servers. In addition, there are several ways to create a service group through VCS Java Console, as well as a generic Application Configuration Wizard. If you prefer to use the command line, that method can be used to create a service group as well.
Creating a VCS service group consitutes the following:
Defining the cluster resources and their attributes.
Setting their dependencies; for example, a NIC resource depends on an IP resource.
Logically grouping the resources together.
Providing capabilities for monitoring the service group and taking it online or offline.
For an example of installing a service group with the Application Configuration wizard:
See Configuring the service group.
The Solutions Configuration Center provides wizards to configure the service groups for the additional SFW HA applications or server roles. It also supports the Application Configuration Wizard which can be used to configure any other application for which application specific wizards have not been provided.
Depending on the application that you have installed, complete the appropriate procedure to configure the service group:
