When trying to live migrate a VM to a neighboring node, it writes an error:
------
Live migration failed "Test-SQL Virtual Machine".

VM migration operation failed for 'Test-SQL' at migration source location 'CLUSTER2-IT'. (Virtual Machine ID: B782C60A-B92F-4271-B3E3-41FC673CF2AD)

"Test-SQL" Synthetic SCSI Controller (Instance ID D78544D1-ECE5-418B-9669-9C75B851B909): failed to disable optimized mode, error "Device does not recognize command. " (0x80070016). (Virtual Machine ID B782C60A-B92F-4271-B3E3-41FC673CF2AD)

What should I do?
