following is my Hyper-v Host configuration.

Hyper-V host running on SSD M.2 and all my VM  VHDX files sitting on local drives (4 x 600 GB Hard Drive - SAS 15K - 3.5" Drives in Riad 5).
I have Two Guest VM's (DC & file server).
I have configured a separate hard disk VHDX (1TB DYnamic) for DATA and attached to my file server.
Then I started transferring my old file server files to new File server DATA Disk.
While transferring data I couldn't access the new file server. The server was in the hung state. But i cold access my other VM which is DC without any issue.

Did the following tuning on Hyper-v setting

Disable VMQ/Enable Jumbo Frame/Disable IPV6
Separate NIC for Management OS and Team NIC for VM's

Allocate 2 Vcpu's and still the same problem.
While transferring the file I am getting the following alert
Disk % Idle Time FAILED on FS01 at Main Office for PhysicalDisk-% Idle Time-_Total result 0

if the idle time is 0 then it means the disk is busy

I have 32 Cores and only have 3 VM's. Is it ok to assign 8 Vcpu's to file server 2 to DC and another 2 to backup transponder
