Found a solution for me. With "diskpart" you can change the disk signature.  Just create i thin clone -> change everytime the signature of new disk clone -> then you can add more thin clones to windows :)
Hello together, whats the best way to make a template of a Virtual Machine with an Equallogic 4100? (I use a Hyper-V Cluster) I thought its easy to create a Volume and install the first virtual Windows Machine on it. When i was ready i disconnected the volume from CSV, Disk Space and iSCSI and converted the Volume to a Template Volume in the Group Manager. Ok, then ive done a thin clone of the template volume und connect it to the Hyper-V Host. For the first VM it works fine. But if i create a second thin clone the Windows Disk Managment say that the Volume is reserved, so i cant put the Volume to the Disk Space and CSV. I think the Problem is the Volume name, that is the same. And i dont know a possibility to change the Volume name without format the volume. I rode the Document  "Dell EqualLogic PS Series Template Volumes and Thin Clones: How and When to Use Them" but i dont want to create a drive letter for the volume for each VM.   How do you do a VM Template?  Greets Marty
