Issue/Introduction

  • Adding esx host to VSAN witness cluster.

  • esx host does not match VSAN witness version.

  • VSAN witness appliance does not match esx version.

  • esx host addition to VSAN witness fails cluster compliance.

  • Unable to cancel failed esx host add task, eventually times out.

Environment

VCF 9.x
VSAN 9.x
vCenter 9.x
ESX 9.x

Cause

VSAN witness and esx host versions recommend to match VSAN version.


Resolution

Update VSAN witness to match esx host version and Build numbers and versions of VMware vSAN.

Additional Information

"Although the vSAN Witness Host is not part of the vSphere Cluster, it is contributing disks to the vSAN Cluster. Because the vSAN Witness Host is contributing to vSAN, it is strenuously recommended to be the same build as the vSAN Data Nodes. It is generally required to be the same release of vSAN."

"If the exact version is not available for download and you downloaded the closest version but not higher than the rest of the cluster upgrade the witness appliance to match the rest of the cluster."
