What's New

vCloud Availability 3.0.3 includes a number of resolved issues and, as a performance improvement, the vCloud Availability services now provide an increased thread count for the internal scheduler.


You upgrade vCloud Availability from version 3.0 to version 3.0.3 by using the command-line interface of the vCloud Availability appliance.  

You can perform an in-place upgrade directly from either vCloud Availability 3.0, vCloud Availability 3.0.1, or from vCloud Availability 3.0.2. 

For more information about upgrading vCloud Availability in the cloud, see Upgrading vCloud Availability. For upgrading the on-premises vCloud Availability appliance, see Upgrading VMware vCloud Availability On-Premises.

Resolved Issues

  • The vCloud Availability Cloud Replicator appliance fails to boot when incomplete offline synchronization replications exist

    After you start a synchronization for a powered off virtual machine that has a configured outgoing replication from the local site to the target cloud site, if you restart the source vCloud Availability Replicator before the offline synchronization completes, the appliance is unable to boot.

  • vCloud Director users are not able to login to the vCloud Availability Tenant portal 

    In vCloud Director 9.1 or later, tenant users attempting to log in by using valid credentials to the vCloud Availability Tenant portal receive an Authentication failed error. Administrator accounts can log in successfully.

Known Issues

  • vCloud Availability 3.0.x cannot operate if the service provider access to the legacy API endpoint is disabled in vCloud Director 10

    If you disable the service provider access to the/api/sessions API endpoint in vCloud Director 10, you cannot log in to vCloud Availability with service provider credentials or organization administrator vCloud Director credentials, you cannot protect or migrate vApps or virtual machines, and in vCloud Director you cannot access the vCloud Availability Plug-in.


    1. Log in or SSH as root to the OS of any of the vCloud Director cells.

    2. Enable the provider access to the /api/sessions API endpoint, use the cell management tool and run the following command:

    ./cell-management-tool manage-config -n vcloud.api.legacy.nonprovideronly -v false

  • The network settings for on-premises to cloud replications cannot be changed

    For on-premises to cloud replications, in the Network Settings window you receive an  Unable to connect to vCenter 'undefined' message. As a result you cannot change the network settings for on-premises to cloud replications.

    Workaround: None.

  • In the same window, enabling the tunnel configuration followed by disabling displays an error message

    In the Tunneling Settings window, if you enable then disable tunneling and click Apply, you receive a "Operation aborted due to an unexpected error" message.

    Workaround: In the Tunneling Settings window, click Cancel. Edit the tunneling settings, enable the tunnel and click Apply. Edit the tunneling settings again, disable the tunnel and click Apply. 

  • Several days after upgrading to 3.0.3 or 3.0.4, the automatic replications sync stops progressing

    After upgrading to vCloud Availability 3.0.3 or to vCloud Availability 3.0.4, in a few days the automatic synchronization of replications ceases to progress. The synchronization task remains as a random percent complete, for example at 28%. This issue prevents new instances from being created and causes RPO violations.


    1. Connect to the vCloud Replicator instance by using a Secure Shell (SSH) client.

    a. Open an SSH connection to the Replicator-IP-Address.

    b. Log in as the root user.

    2. Add the following configuration property.

    echo “TRAFFIC_ACCOUNTING=false” >> /opt/vmware/h4/lwdproxy/conf/

    3. Restart the lwdproxy service.

    systemctl restart lwdproxy

    4. Log in to the vCloud Availability Portal as a tenant or as a service provider.

    5. To verify that the replications synchronization is operational, select a replication and click the Sync button.

    6. Repeat this procedure for all vCloud Availability Replicator instances.
