vCloud Director 9.5 for Cross-VDC , requirement ?

Hello,

We are trying to set up a dual site vCloud Director with 9.5 version.

So we are testing cross VDC, we have configured two distinct orgVDC from two distinct provider VDC.

Each provider VDC comes from a vCenter RG / NSX Manager and we have only one instance vCD for both provider VDC.

We cannot configure the org VDC for Cross-VDC option, the option could not be enabled, we have followed several blogs and sources but still have an error.

Do we miss something ? Can we set up cross-vdc with only one instance VCD and two vCenter / NSX mananger ?

We are contacting Vmware for PSO services but the team is busy we need to wait until they can.

Best regards

Hello,

We find the solution, vCloud portal is trying to reach a FQDN pointing to the public VIP url in front of the two cell (portail url vcd), the fw / lb was blocking the access.

Solution was to modify /etc/hosts of each cell in order the public VIP url to point to the local ip of the cell.

Can you provide further details on why Cross-VDC cannot be enabled and what errors you are seeing?

Hi Daniel,

We forgot to configure nsx manager options on both vCenter under our vCD portal,  it is a little bit better, we can now enable VDC cross option on both org VDC.

We have now another error on the next step when configuring datacenter group. Here is the error :Unable to query VDCs from all sites for VDC Group LABJN

Can we configure Cross VDC with one instance vCD 9.5 and two vCenter / NSX ? Or maybe it is not possible with 9.5 version ?

Best regards

Is this error after attempting to create the Datacenter Group?

You should able to create a Datacenter group between two distinct pVDCs that have two distinct fault domains (Network Provider Scope) in the NSX Manager subtab -

Yes when we are configuring the datacenter group, we have the following error.

Cross-VDC is working with only one vDC instance ? Or we need to configure instance vCD on each site ?

I don't see any further error detail or screenshots.

Cross-VDC requires a minimum of two orgVDCs each with a respective fault domain. I've done extended testing between two vCD instances, but I just verified that it should work within a single vCD instance too (assuming you have separate providerVDCs each with a respective fault domain / network provider scope).

Thx for the response.

Sorry, the error is Unable to query VDCs from all sites for VDC Group LABJN.

And yes we have two distinct provider VDC provided by a distinct vCenter / NSX / ESXi ressource group.

Let's get an SR open please. You can tell the GSS TSE to reference my name so we can take a look at the stack trace. Thanks.
