Environment

VMware Cloud Director 10.x

Cause

This is expected behaviour as the two resource Pools that are being used are not elastic.

An Organization VDC cannot use the resources in both/multiple clusters when the elastic setting is disabled.

Resolution

To resolve the issue, enable the elastic option so that the Organization VDCs can use resources from multiple clusters:

1. On the Provider Portal, click on the Administration Tab.
2. Under the Settings tab, click General.
3. On the section for Other click the Edit button.
4. Enable the toggle for Make Allocation Pool Organization VDC's elastic.
5. Click Save.
6. Wait for a few minutes for the new change to be applied.
7. Migrate the VMs.
