Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Troubleshooting CVM and VVR components of SFCFS
The following topic is useful for troubleshooting the VVR component of SFCFS.
Updating the rlink
If the rlink is not up to date, use the hares -action command with the resync
action token to synchronize the RVG.
The following command example is issued on any node (galaxy, in this case) in
the primary cluster, specifying the RVGSharedPri resource, ora_vvr_shpri:
# hares -action ora_vvr_shpri resync -sys galaxy
VCS agents to manage wide-area failover
VCS agents now manage external objects that are part of wide-area failover. These
objects include replication, DNS updates, and so on. These agents provide a robust
framework for specifying attributes and restarts, and can be brought online upon
fail over.
VCS provides agents for other array-based or application-based solutions. This
section covers the replication agents that is bundled with VVR. See the VCS
replication agent documentation for more details.
Note: See the Veritas Cluster Server Agents for Veritas Volume Replicator
Configuration Guide for more information about the RVG and RVGPrimary agents.
Note: The RVGSnapshot agent is not supported for SFCFS.
DNS agent
The DNS agent updates the canonical name-mapping in the domain name server
after a wide-area failover. See the Veritas Cluster Server Bundled Agents Reference
Guide for more information about the agent.
RVG agent
The RVG agent manages the Replicated Volume Group (RVG). Specifically, it
brings the RVG online, monitors read-write access to the RVG, and takes the RVG
offline. Use this agent when using VVR for replication.
