Check description: Checks if any faulted VCS resource of each configured VCS group.


Check procedure:

  • Fetches the resources from all the systems specified for executing the check.
  • Determines whether the resources are in a FAULTED state.


Check recommendation: A group cannot failover to a system where the Cluster Server (VCS) resource has faulted. Fix the problem that caused the fault. To clear the VCS fault for resource resource_name on node node_name login as root enter:
#hares -clear resource_name node_namei.
If a parallel service group like Cluster Volume Manager(CVM) or Cluster File System (CFS) fails,clear the VCS fault for the service group and bring the service group online. Log in as root and enter:
#hagrp -clear service_group_name -sys node_name.
#hagrp -online service_group_name -sys node_name

Check description: Checks for mirrored volumes that do not have a Dirty Region Log (DRL).


Check procedure:

  • Identifies any mirrored volumes present on the system.
  • Verifies if the mirrored volumes have a Dirty Region Log (DRL)


Check recommendation: The mirrored volume(s) do not have a DRL. Make sure that you create a DRL for any mirrored volumes. A DRL tracks the regions that have changed. Having a DRL helps with data recovery after a system crash. The DRL uses the tracking information to recover only those portions of the volume that need to be recovered. Without a DRL, recovery involves copying the full content of the volume between its mirrors; this process is lengthy and I/O intensive.
