The source was a CSV and the destination was a?

Please post the results of the following PowerShell (elevated if GUI installed):

All nodes in the cluster:
Get-VMHost | fl VirtualHardDiskPath,VirtualMachinePath

One node in the cluster:
Get-ClusterNode | foreach {Get-VMHost -ComputerName $_.Name} | ft ComputerName,VirtualHardDiskPath,VirtualMachinePath -AutoSize


The only time we've seen issues with Storage Migrations was when node setups were not identical, storage was not set up identically across all nodes, the above settings were not configured correctly, or on smart storage the LUNs were not shared correctly across all nodes.

Is the cluster fully patched with hotfixes applicable to the OS running on the nodes for cluster being applied?

from one csv to another csv

One other thing, i have snapshots on Lun from which i have migrated and tried to attach a snapshot to see it on a host, i see the disk but cant do anything with it. i thought to mount a snapshot and copy the vhdx files that are "clean", since it is a production i dont really want to fiddle with it, tried to find some info on EMC pages but nothing, suppose snapcli is not used anymore....

A Hyper-V snapshot or one done in the storage management console?

Is the cluster up to date including all relevant hotfixes for Hyper-V and cluster?

Please post the PowerShell results.

The VM was online when the Storage Live Migration took place I take it? Did it BSOD just after the SLM completed or before?

Does Failover Cluster Manager have any errors logged?

Machine was online unfortunately, no errors logged. i think it went down just after migration was over
copied vhdx back to original csv (i wanted to work on the copy) , didn't work, after a while i get to them and mount them succesufully :)
reconfigured the vm to point to disk that i have copied and it works, i don't now really, it is late/early(5am), one machine solved, one more to go.
