When you want to update a base layer, but the reference machine that was used to create the original base layer is not available, you can recreate the original reference machine from the existing base layer.
- In the Mirage Management console, expand the Image Composer node and select the Base Layers tab.
- Right-click the base layer and select Create Reference CVD from layer.
- Select a pending device and click Next.
- Select an upload policy and click Next.
- Click Finish.
What to do next
Use a Mirage restore operation to download and apply the image of the original reference machine to a selected device to serve as a new reference machine. See Restoring to a CVD After Hard Drive Replacement or Device Loss. You then update or install core applications and apply security updates on the new reference machine before you capture a new base layer using the existing reference CVD.
