Host status 'unknown' in vLCM

Products

• VMware vSphere ESXi

Issue/Introduction

The ESXi host status is showing as 'unknown' after remediation

 

Or the ESXi host stops part-way through remediation and produces the error:

Host status is unknown

The host could not be reached, and its image compliance could not be checked.  Try refreshing image compliance again - the host may be reached successfully.

During remediation, this host may get remediated if it can be reached successfully.

Environment

ESXi 7.0.x
ESXi 8.0.x
vCenter Server 7.0.x
vCenter Server 8.0.x

Cause

Communication issues between the ESXi host and the vCenter/vLCM application.

Resolution

Initially try doing a disconnect & reconnect the ESXi host in vCenter Inventory.

If that doesn't resolve the issue, gracefully reboot ESXi host.
