Hi Yiping, See https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.vcenterhost.doc/GUID-EC0F7308-96AE-4089-9DD4-B42AF50AABDC.html
You should find a custom attribute to your virtual DC called something like "cloud.zone" which I believe you have to wipe before you can re-add it to a new CloudStack instance. If the above doesn't work you may have to drop to command line and do it with something like PowerCLI. With regards to deploying a full zone this is part of what Trillian https://github.com/shapeblue/Trillian does in it's cloudstack-config role - but please be aware this role simply populates a "deployzone.sh" jinja template with the right options before running this as a normal bash script.

I have some general questions regarding such a set up: My first attempt had some errors, so I decided to blow away the CloudStack database and start from scratch again. Now when I try to add VMware datacenter to the zone, I receive an error message saying that: “Failed to add VMware DC to zone due to : This DC is being managed by other CloudStack deployment. Cannot add this DC to zone” This sounds like my last try has left something on the datacenter in vCenter so that I can’t associate it to another zone any more. If this is true, do I have to blow away the datacenter in vCenter as well to start over again? Is there any way to clean up on the vCenter side without rebuilding the datacenter? In hindsight, I should have deleted all CloudStack objects from web GUI instead of taking the nuclear option of blowing away the database! A related question, has anyone used CloudStack ansible module to deploy a complete zone (including all necessary objects zone/pod/physical networks/cluster/host/primary_storage/secondary_storage etc)? If so, would you mind sharing your ansible playbook(s)? Thanks, Yiping [email protected] www.shapeblue.com Amadeus House, Floral Street, London WC2E 9DPUK @shapeblue
