In an environment with multiple vCenter Server instances, the names of availability zones on the VMware Integrated OpenStack dashboard might differ from those on the OpenStack Management Server.
If you use the command-line interface to rename availability zones, you might see different names in the vSphere Web Client and the VMware Integrated OpenStack dashboard. In the Availability Zones column on the tab for your deployment, desynchronized availability zones are displayed in red. You can resynchronize the availability zones to fix the issue.
