No problem Corey, I don't think that is documented anywhere. Cloudstack marks the DCs that are under its supervision so when you re-add them it thinks they are already managed. To remove the mark:
* Go to vCenter * Right click on the DC -> Tags and custom attributes -> Edit custom attributes. * Delete the attribute with name cloud.zone * Try to add the DC again to Cloudstack Btw I am making a list of things that needs to be updated in the documentation so if anyone have any similar notes but do not have time to add, let me know. I am working towards a POC in the end of the month but after that I will occasionally start contributing.

[X]This message came from outside your organization Sorry to keep you so busy today... Needless to say my initial zone creation failed. I have removed the custom attributes in vCenter; however I'm still getting the error below when trying to run through the zone wizard again. "Failed to add VMware DC to zone due to : This DC is being managed by other CloudStack deployment. Cannot add this DC to zone." As said, I removed the custom attributes and restarted ACS. https://basu.co.in/2014/10/28/how-to-re-use-vcenter-in-cloudstack/<https://urldefense.com/v3/__https:/basu.co.in/2014/10/28/how-to-re-use-vcenter-in-cloudstack/__;!!A6UyJA!34PcvW0zJ9I1c36Auer98N_5opeTx8HvTcI868XB3ifGOoFX0C0ZBWKOq8PoOHdwh2rq1T9N3sYZ$> https://support.accelerite.com/hc/en-us/articles/360030933432-This-DC-is-already-part-of-other-CloudStack-zone-s-Cannot-add-this-DC-to-more-zones-<https://urldefense.com/v3/__https:/support.accelerite.com/hc/en-us/articles/360030933432-This-DC-is-already-part-of-other-CloudStack-zone-s-Cannot-add-this-DC-to-more-zones-__;!!A6UyJA!34PcvW0zJ9I1c36Auer98N_5opeTx8HvTcI868XB3ifGOoFX0C0ZBWKOq8PoOHdwh2rq1XiJc5GX$> Is there something I need to clean up in the SQL?
