Restore. Disks are greyed out (4040105)

 The problem occurs if 2 following conditions are met during backup:

1. VM has a custom snapshot before backup;
2. Quiesced backup is configured.

In this case, disk information in SavePoint Manifest.metadata does not match one in VmConfig.metadata

1. Get current delta file name from VmConfig. In example below it is Paul-2K12-000001.vmdk

VmConfig.metadata excerpt

<a:DiskLayout xmlns:b="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
  <b:anyType i:type="a:FileLayout">
    <a:Files>
      <b:string>[iSCSI4] Paul-2K12/Paul-2K12.vmdk</b:string>
      <b:string>[iSCSI4] Paul-2K12/Paul-2K12-000001.vmdk</b:string>
    </a:Files>
    <a:Key>2000</a:Key>
  </b:anyType>
</a:DiskLayout>

2. Change SourceFile value in Manifest.metadata to match one in VmConfig

from
SourceFile="'vix:1:r:vc-vs-vsphere55.prod.quest.corp\:443:902:[iSCSI4] Paul-2K12/Paul-2K12-000003.vmdk'
to
SourceFile="'vix:1:r:vc-vs-vsphere55.prod.quest.corp\:443:902:[iSCSI4] Paul-2K12/Paul-2K12-000001.vmdk'

3. Create Restore from Manifest (RFM) job.
