In the VC GUI  Host and Cluster view :  Host > Monitor > Task & Events > Tasks shows the following error

Status: The host returns esxupdate error code:99. An unhandled exception was encountered.Check the Update Manager log files and esxupdate log files for more details

Cause

This issue occurs due to smaller hostd resource group in vSAN Witness node ESXi hosts compared to normal ESXi  hosts to process large number of metadata files during host scan or remediation.

Resolution

Upgrade vCenter to 7.0U1 or higher

Related Information

Using vSphere Update Manager to upgrade hosts in parallel might result in the witness host being upgraded in parallel with one of the data hosts in a stretched cluster / 2-Node configurations.
To avoid upgrade problems, do not configure VMware Update Manager to upgrade a witness host in parallel with the data hosts in a stretched cluster.
Upgrade the witness host after all data hosts have been successfully upgraded and have exited maintenance mode.

For more information see vSAN Witness Appliance Upgrade.
