Error ID- 1001 During the Hyper-V VM Recovery from DPM 2012 R2

Hi 

I am getting Error ID 1001 while starting the Recovery of multiple Hyper-V VM/Vhd  from DPM 2012 R2. 

I am able to Recover some VHD and SQL DB from same DPM server.

I have created only one Protection Group of All Hyper-V VM machines Backup in DPM. Backup is successful, able to view the content & recovery Point of All VMs but while trying to recover such multiple VMs getting Error ID 1001 . No any ther Server Events. 

Tape Library and its Drive`s Firmware is already latest. Server OS is Server 2012 R2 and Data base is on same server with Default instance.

Please suggest for solutions..
