Before you configure the Sybase service group, you must meet the following prerequisites:

• Verify that VCS is installed and configured on all nodes in the cluster where you plan to configure the service group. For more information on configuring VCS see the Cluster Server Configuration and Upgrade Guide.

  Caution:

  In Sybase cluster edition, the Sybase agent assumes that the membership-mode is set to vcs. When Sybase instances are configured under VCS control, the installer automatically sets the membership-mode to vcs. If the Sybase server instances are configured manually under VCS control or if the quorum device is rebuilt in 'native' mode, ensure that the membership-mode is set to vcs.

• Verify that Sybase is installed and configured identically on all nodes in the cluster.

• Verify that the Cluster Server agent for Sybase is installed on all nodes in the cluster.

• Verify the type definition for Cluster Server agent for Sybase is imported into the VCS engine.
