Your installation can fail if the IaaS installer is unable to save the Model Manager Data component and Web component.

Your installation fails with the following message: The IaaS installer failed to save the Model Manager Data and Web components.

The failure has several potential causes.

Connectivity issues to the vCloud Automation Center Appliance or the Identity Appliance or connectivity issues between the appliances. A connection attempt fails because there was no response or the connection could not be made.

Trusted certificate issues in IaaS when using a distributed configuration.

Trusted certificate issues between the vCloud Automation Center Appliance and the Identity Appliance.

A certificate name mismatch in a distributed configuration.

The certificate may be invalid or an error on the certificate chain might exist.

The Repository Service fails to start.

Loopback problem or incorrect configuration of the load balancer in a distributed environment.


Check that you can connect to the vCloud Automation Center Appliance by typing the following URL in a Web browser: https//

Trusted certificate Issues

In IaaS, open Microsoft Management Console with the command mmc.exe and check that the certificate used in the installation has been added to the Trusted Root Certificate Store in the machine.

From a browser check https://<ip-web>/repository/data/MetaModel.svc and verify that no certificate errors appear in your browser.

Certificate Name Mismatch

This error can occur when the certificate is issued to a particular name and a different name or IP address is used. You can suppress the certificate name mismatch error during installation by selecting Suppress certificate mismatch.

You can also use the Suppress certificate mismatch option to ignore remote certificate revocation list match errors.

Invalid Certificate

Open Microsoft Management Console with the command mmc.exe. Check that the certificate is not expired and that the status is correct. Do this for all certificates in the certificate chain. You might have to import other certificates in the chain into the Trusted Root Certificate Store when using a Certificate hierarchy.

Repository Service

Use the following actions to check the status of the repository service.

From a browser, check the status of the MetaModel service at https://<ip-web>/repository/data/MetaModel.svc.

Check the Repository.log for errors.

Reset IIS (iisreset) if you have problems with the applications hosted on the Web site (Repository, vCAC or WAPI).

Check the Web site logs in %SystemDrive%\inetpub\logs\LogFiles for additional logging information.

Verify that Prerequisite Checker passed when checking the requirements.

On Windows 2012, check that WCF Services under .NET Framework 4.5.1 is installed and that HTTP activation is installed.

Loopback check

You must disable the Microsoft loopback check on the Model Manager machine to install the Model Manager Data Component in a load balanced environment.

See the following Microsoft KB article for information on how to disable the loopback check feature: If you follow the first method described in this article, and use multiple load balancers or load balance layers, be sure to specify each host name when you disable loopback check. The installation fails, otherwise.
