Veritas InfoScale™ 7.3.1 Release Notes - Linux

VVR configuration may go in a primary-primary configuration when the primary node crashes and restarts [3314749]

The AutoResync attribute of the RVGPrimary and RVGSharedPri agent control whether the agent must attempt to automatically perform a fast-failback resynchronization of the original primary after a takeover and after the original primary returns. The default value of this attribute is 0, which instructs the agent not to perform a fast-failback resynchronization of the original primary after a takeover and after the original primary returns. The takeover is performed automatically since the default value of the AutoTakeover attribute of the RVGPrimary and RVGShared agents is 1. Thus, the default settings of AutoTakeover and AutoResync set to 1 and 0 respectively cause the first failover to succeed when the original primary goes down, and on return of the original primary, the Replicated Data Set (RDS) ends up with a primary-primary configuration error.

Workaround: Set the default value of the AutoResync attribute of the RVGPrimary agent to 1 (one) when you want the agent to attempt to automatically perform a fast-failback resynchronization of the original primary after a takeover and after the original primary returns. This prevents the primary-primary configuration error. Do not set AutoResync to 1 (one) if you intend to use the Primary-Elect feature.

Moreover, if you want to prevent VCS from performing an automatic takeover and fast-failback resynchronization, set AutoTakeover and AutoResync attributes to 0 for all the RVGPrimary and RVGSharedPri resources in your VCS configuration. For more information, refer to the RVGPrimary and RVGSharedPri agent sections of the Replication Agents chapterin the Cluster Server Bundled Agents Reference Guide.
