Environment

VCF 9.0.1

Cause

For the DVS port group used by vCenter, there is another port group within the vCenter (including Datacenter/Cluster) having the same port group name.

In such situation, the pre-check is unable to confirm the vCenter VM's port group, leading to the per-check failed.

 

Resolution

- Find out the duplicated port group and rename it with new name, then retry the validation task.

- Create a SR to VMware by Broadcom for further investigation.
