I have a Hyper-V server running a database VM. I want to backup the SAN drive that is directly connected to that VM. When we setup the VM we connected the SAN drive to the hyper-v server and, per documentation, took it offline and attached it to the VM.
I need to remove this drive from the VM, copy the files (I can't from inside the VM due to other constraints) and remount the drive on the VM. This sounds simple in theory but I fear dismounting the drive and not getting it back online. Is this a straightforward thing that I am being paranoid about or am i right to be worried?
Any advice on how to safely dismount, clone and remount this SAN drive in hyper-v will be greatly appreciated.
