If you plan to configure secure communication among clusters in the global clusters, then you must meet the following prerequisites:

• You must configure the wide area connector processes in both clusters to run in secure mode.

  When you configure security using the installer, the installer creates an AT account for the wide-area connector also.

• Both clusters must run in secure mode.

  • You can configure security by using the installvcs -security command.

  For more information, see the Cluster Server Installation Guide.

• Both the clusters must share a trust relationship. You can set up a trust relationship by using the installvcs -securitytrustcommand.

  For more information, see the Cluster Server Installation Guide.
