RAID array goes into fault status when installing OS

[Austin P]

I am thoroughly confused.  I have a C240 M4 I recently got and bought a UCSC-MRAID12G-1GB for it.  I plugged a pair of 1TB Samsung 870 EVO SSD's into it and tried to configure them in a RAID 1 array.  Works fine until I go to install Windows Server to it... after I select the drive (virtual drive created in CIMC) and click next it either errors out or get's stuck at 0% Copying Files and the raid array goes into fault status in CIMC for a variety of reasons:

-Drive in bay 1 in unknown state

-Drive in bay 1 in failed state

-Drive in bay 2 in unknown state

-Drive in bay 2 in failed state

-Both drives in failed state

-Both drives in unknown state

Am I doing something wrong or do I probably have a bunk raid card?

  - Perhaps Windows has an incorrect driver for the raid array (or even none) ?

It seems to detect the array once I load the raid controller driver, when I go to install is when I have the issue.  But it does also happen prior to booting to the installer as well.  I bought another controller do verify its not just a bunk slot on my board.

That raid controller (and it's firmware) was tested with specific sets of drives (https://www.cisco.com/c/dam/en/us/products/collateral/servers-unified-computing/ucs-c-series-rack-servers/c240m4-sff-spec-sheet.pdf).
Would have to look at raid controller logs to see if something is causing the controller to crash/restart.

By which you mean Storage Logs in CIMC?  Saw tons of "Unexpected sense" errors.  Not sure if backplane, drives, board, controller, or what...

I did also try downgrading the firmware of the controller.  Was of no help.

The controller itself did go into unresponsive status twice yesterday so I'm thinking controller.
