VSAN network is not configured on {} in cluster {} in datacenter {}.


There is an issue with virtual SAN network configuration on one or more hosts in the cluster.


Check configuration of network interfaces.

  • Make sure that hosts participating in the Virtual SAN cluster are part of Virtual SAN network and are in the same subnet.
  • Check that at least one Virtual SAN interface is configured on each host in the cluster (regardless whether the host contributes to storage or not).
  • Keep in mind that VSAN networking does not support IPv6.

Refer to this VMware KB article for configuring Virtual SAN VMkernel networking.

Review VMware online documents such as Troubleshooting Virtual SAN to resolve the issues.


Refer to the VMware Online Documentation for more information on vCenter event messages and possible solutions.
