I was able to create the SHR using PCIe passthrough using 3-3TB SATA drives and 2 64 GB SSD drives I used for cache.
Can I ask what sata card you have for PCIe pass through?
Also, did you have to create a RAID group first before creating the Volume?
It seems I have to create a raid group and then can create a volume from there. But there is no SHR option.
