During a restore of a vm, the disks may be greyed out so that you are unable to restore the VM.
At the time the VM was backed up, the VM may have been directly on the root of the datastore.
For example, a typical VM disk path is as follows: [Datastore] VM_Folder/VM.vmdk
However, in some cases your VM disk path may be as follows: [Datastore] VM.vmdk
The vRanger issue is due to the non-standard disk path.
A restore from manifest is the easiest way to restore the disks in a VM that is not using a standard disk path.
Before you begin the restore task you will need to edit the VM savepoint's manifest.metadata file.
Look for the following in the file:
<FileMapEntry SourceFile="'vix:r:Host_Name:902:[Datastore] VM.vmdk'"
Add a folder in the disk path in the variable. For Example:
<FileMapEntry SourceFile="'vix:r:Host_Name:902:[Datastore] NewFolderName/VM.vmdk'"
Save the file and begin the restore from manifest.
