Environment

VMware Cloud Foundation 9.0

VMware vSphere Foundation 9.0

Cause

The issue is primarily caused by host-sync operation failures. It is expected to occur mostly in test environments, where activity is minimal. In actual live environments, ongoing operations typically trigger host-sync processes, which in turn prevent the issue from occurring.

Resolution

Resolved in future VCF release

Workaround Steps:

1. Disable MOB for target vCenter (vCenter 9 MOB is disabled by default. If its enabled, then disable it) - Refer How to disable access to the Managed Object Browser in vCenter Server.
2. Enable / Disable SSH for managed hosts within this vCenter
3. Restart import workflow in VCF installer
