Veeam VMware: Virtual SAN Health Alarm 'Unicast agent configuration inconsistent'

Veeam.Virt.Extensions.VMware.VSAN.VMCCR.VirtualSANHealthAlarmUnicastagentconfigurationinconsistent (UnitMonitor)

Knowledge Base article:

Summary

This monitor tracks the Virtual SAN Health Alarm 'Unicast agent configuration inconsistent'.

Causes

The purpose of the Unicast agent configuration inconsistent check is to ensure that all unicast agent addresses point to the witness host. If the check fails, this means that the vSAN stretched cluster has a configuration issue.

For more information on the Unicast agent configuration inconsistent check, see this VMware KB article.

Resolutions

Make sure that all unicast agents have consistent configuration across all ESXi hosts in the cluster. To do that, follow the instructions provided in this VMware KB article.

Use the results of the Unicast agent configuration inconsistent check to verify that all unicast agents are configured with valid IP addresses and ports.

For more information on troubleshooting Virtual SAN issues, see VMware Docs.
