vSAN Cluster Configuration Issues

After you change the vSAN configuration, vCenter Server performs validation checks for vSAN configuration.

Problem

Error messages indicate that vCenter Server has detected a problem with vSAN configuration.

Note: Validation checks are also performed as a part of a host synchronization process.

Solution

If vCenter Server detects any configuration problems, it displays error messages. Use the following methods to fix vSAN configuration problems.

Table 1. vSAN Configuration Errors and Solutions

vSAN Configuration Error	Solution
Host with the vSAN service enabled is not in the vCenter cluster	Add the host to the vSAN cluster. Right-click the host, and select Move To. Select the vSAN cluster and click OK.
Host is in a vSAN enabled cluster but does not have vSAN service enabled	Verify whether vSAN network is properly configured and enabled on the host. See vSAN Planning and Deployment.
vSAN network is not configured	Configure vSAN network. See vSAN Planning and Deployment.
Host cannot communicate with all other nodes in the vSAN enabled cluster	Might be caused by network isolation. See the vSAN Planning and Deployment documentation.
Found another host participating in the vSAN service which is not a member of this host's vCenter cluster.	Make sure that the vSAN cluster configuration is correct and all vSAN hosts are in the same subnet. See vSAN Planning and Deployment.
