LSI2308 in Z840 - Drives not visible to Windows10

HP Recommended
HP Z840
Microsoft Windows 10 (64-bit)

I have a Z840 workstation with an SSD drive in the SATA2-port 0 and Windows 10 Pro runs fine. Then there are four 3TB HGST NAS SATA III drives in the lower SAS ports 0 thru 3. 

 

I configured a RAID 10 array and created a single volume to use the entire 5.457 TiB of space. I ran the initialization first in the LSI2308 Config Utility from BIOS. The volume is not visible to Windows 10. I then deleted the volume, reran the setup from LSI's MegaRAID manager in Windows. Same problem. After initializing for 12+ hours in both efforts, the array and volume are not visible in Windows 10 file explorer, nor the Intel RSTe.. I can see the disk0 space in Windows Disk Management as unallocated space, but cannot do anything with it. I can also see the initialized volume in the LSI 2308 MegaRAID manager. Cannot do anything with it.

 

What am I missing here? There is no place to format an NTFS on the volume. Can someone please help?? I'm not 4 days into this and no further along than I was on Day 1. HP Support spent 2 hours last night trying to assist but also could not figure out the problem.

 

Should I put the SSD bootable Win disk in the SAS ports as well (port 0) and move the RAID drives to ports 1-4?

 

Thanks for any ideas that work.
