Replying to mark TOTAL OF ALL PREVIOUS POSTS IN THIS DISCUSSION as the SOLUTION. But please continue to post any questions/comments.
I noticed that many discussions specify DP4400 in the Subject. *All should be aware that most of the solutions given for DP4400 also apply directly or with slight modification to other models. I suggest people posting discussions not narrow the Subject to DP4400 unless they are sure it only applies to that model. If not sure, you can not include the model in the Subject and mention in the comments what model you know it does apply to and that you are not sure if it also applies to other models. This way people with DP5xxx/DP8xxx may find what they are looking for easier, and people can follow-up with comments to clarify which model(s) it applies to.  For those not familiar: DP4400 has one esxi host and all other components are VMs. DP5xxx has three esxi hosts forming a vSAN and all components are VMs except there is a physical Data Domain (Protection Storage). DP8xxx has three esxi hosts forming a vSAN and all components are VMs except there is a physical Data Domain (Protection Storage) and a physical Avamar (Backup Server).  Other than networking details and physical DD or AV hardware issues, most solutions should be the same across all models, but do confirm if not sure before doing anything risky. If you have any questions/comments along these lines please post here and we will try to follow-up. If this helps please give KUDOS.  thanks
models DP5xxx and/or DP8xxxx
