VMware HA Agents Fail to Automatically Reconfigure After Network Connectivity is Restored
Details
In cases where multiple hosts experience a simultaneous network isolation (all of them losing network connectivity at the same time), the VMware HA agents running on these hosts may fail to automatically reconfigure and rejoin the HA cluster after the network connectivity is restored.
Solution
There is a workaround for this issue. You need to manually reconfigure VMware HA on each host or do a cluster-wide VMware HA reconfiguration. For more details, refer to the steps outlined in the Troubleshooting section of the file attached to this knowledge base article.
