  Expect 1 but 0 found for DistributedVirtualPortgroup:<az2_PORTGROUP_NAME>

  • az2_PORTGROUP_NAME is the name of an az2 port group in the specific environment.

Environment

VMware Cloud Foundation 5.x

Cause

• An az2 portgroup has been removed from the vCenter directly, the SDDC Manager is not aware of the removal having happened.
• This can be verified by reviewing the vCenter UI to see if the az2 port groups are all present or if one or more are missing.

Resolution

• The resolution here requires editing the SDDC database in order to skip the subtask to "Remove AZ2 Portgroups" and allow the workflow to complete.
• Contact Broadcom support to perform this resolution.
