Ok i got the issue resolved with the assistance of Dell support.  The issue was discribed to me like this... "There is a glitch with the HBA firmware that will cause this issue in rare instances – mainly related to reconfiguration of the HBA from one configuration to another (additional disks/different disks) and it becomes unable to update the configuration.  What you are seeing (discrepancy between what is seen from the iDRAC/OMSA vs. what is seen in the OS) fits the issue." Support provided an .IMG file I booted the server with and it cleared the bad disk config. Once that was done all of the disks are available and everything is working correctly. The support tech asked that I not share the IMG file but at least you know what to ask for if someone else comes across the same issue.  A big thanks to the support guys at Dell for fixing this for me. 
We recently purchased several R730xd with HBA330 mini to use in Storage Spaces Direct. We went with a 12-4-2 configuration. However even that the HBA sees all drives in Bios  it reports only 1 of the 4 drive seated on the 4-disk extra carriage. Server has the latest 2016 Updates and also the latest firmware/bios/drivers for Server and HBA from Dell.  Any ideas?
HBA330 Mini not reporting All drives in O/S
