Purpose

This article explains the Cluster Health – vSAN Health service installation check in the vSAN Health Service in vSAN (formerly known as Virtual SAN) and provides details on why it might report an error.

Resolution

Q: What does the Cluster Health – vSAN Health service installation check do?

This check verifies that all ESXi hosts have the vSAN Health Service VIB installed.

Q: What does it mean when it is in an error state?

If the check reports an error, it means that one or more ESXi hosts do not have the health service installed. You may need to update the ESXi host to the version that matches the vCenter server or install the corresponding vSAN Health VIB onto the host with errors. On vSphere 6.0 Update 2 release, none of the other health checks will be conducted until all the hosts are upgraded to 6.0 Update 2 (when running the latest version, vSAN 6.2) release to avoid false alarms.

Q: How does one troubleshoot and fix the error state?

Install the vSAN Health Service VIB on all the ESXi hosts that are participating in the vSAN cluster, or update the ESXi host to the version that is indicated in the error field.

For vCenter Server versions prior to vSphere 6.0 Update 2, failure of this health check means that the health service VIB installation failed on one or more ESXi hosts. You may go to the Cluster > Manage > Settings > Virtual SAN > Health tab to install the health VIB on the hosts which are missing the health service VIB. There are also a number of alternatives to achieve this. For more information, see the Installation section of the VMware Virtual SAN Health Check Plugin Guide.

For vCenter Server 6.0 Update 2: if the check reports an error, it most likely it means there is at least one ESXi host in the cluster running an earlier version of ESXi. As vCenter Server 6.0 Update 2 can only manage same version of ESXi hosts, in order to have the health check working correctly all the ESXi hosts need to be upgraded to version 6.0 Update 2.
