Note that the virtual machines must be powered down. Ensure that the virtual disks properties are set to the following:
- Sharing: Multi-Writer
- Disk Mode: Independent - Persistent
- The first scsi controller should have all of the data volumes and the second controller should have all of the volumes intended to be used for logging. For a scale out 3+1 implementation there should be 6 disks in total access by 4 virtual machines.
- If the VM has used Change Block Tracking (CBT) before then there is a configuration option set for it which will block Multi-Writer Disks being used. To disable CBT follow this guide.
