How VCS recovers from various disasters in an HA/DR setup with EMC SRDF
This topic lists various failure scenarios and describes how VCS responds to the failures in the following DR cluster configurations.
When a site-wide global service group or system fault occurs, VCS failover behavior depends on the value of the ClusterFailOverPolicy attribute for the faulted global service group. The VCS agent for EMC SRDF ensures safe and exclusive access to the configured EMC SRDF devices.
See Failure scenarios in global clusters.
When service group faults or system faults occur, the VCS failover behavior depends on the value of the AutoFailOver attribute of the faulted service group. The VCS agent for EMC SRDF ensures safe and exclusive access to the configured EMC SRDF devices.
See Failure scenarios in replicated data clusters.
Refer to the Cluster Server Administrator's Guide for more information on the DR configurations and the global service group attributes.
