Configuring the CSSD resource

You must configure the CSSD resource to ensure that the CSSD dependencies on the resources that manage OCR and voting disk and the private IP address are satisfied before Oracle Clusterware/Grid Infrastructure starts.

Note:

It is mandatory to use CSSD agent in SF Oracle RAC installations. Using the CSSD agent ensures adequate handling of inter-dependencies, thus preventing the premature startup of Oracle Clusterware/Grid Infrastructure, which causes cluster failures.

Before you configure the CSSD resource, make sure that the following requirements are satisfied:

  1. Oracle Clusterware/Grid Infrastructure is up and running.

  2. OCR and voting disk is configured on CVM raw volumes or CFS and managed by VCS.

  3. The private IP address for Oracle Clusterware/Grid Infrastructure is configured under the PrivNIC or MultiPrivNIC resource in the same VCS group as that of OCR and voting disk.

    Note:

    The SF Oracle RAC installer configures the OCR, voting disk, and PrivNIC/MultiPrivNIC resources in the cvm group. If you configured one of these resources manually, make sure that these resources are placed in the cvm group. If the resources are not in the same group, configure the CSSD resource manually.

    See Configuring the CSSD resource manually.
