An existing MCS Catalog with no hibernation support is being updated to support hibernation.  Azure hibernation has been enabled on the base image, the image template, and the MCS Catalog.  However, after performing an Image Update on the Catalog, the provisioned VDAs still do not support hibernation.

Obtain the ProvisioningSchemeName and MachineProfile path by performing the following query and selecting the correct value.

• Get-ProvScheme | Select-Object ProvisioningSchemeName,MachineProfile

Use the obtained values, set the Provisioning Scheme properties, forcing an update of the template information.

• Set-ProvScheme -ProvisioningSchemeName <provisioning-scheme-name> -MachineProfile <path-to-template-with-hibernation-enabled> 

---

Problem Cause

DaaS will only import the template properties when setting the MachineProfile path.  If a Catalog is deployed without hibernation, and hibernation is later enabled, the MachineProfile path must be manually set again on the Provisioning Scheme in order to force a refresh of the template data and include the "HibernationEnabled": "[parameters('SupportsHibernation')]" property.

Azure hibernation requires a change to the template, and the template properties are only updated when setting the MachineProfile property.
