AJ12,   Was the H330 order with the system, or was it added afterwards? If added afterwards, would you verify the part # found on the controller? If ordered with the server, then I would lean towards the possibility of the controller having failed.  
Hello, T430, H330 Boot: SATA SSD connected to motherboard, works fine without H330 card.    Previously this server was working perfectly. After installing a Mellanox SFP+ card the system became unstable and would crash. The card was removed and then the machine would not boot. Connecting to a monitor I get the "Avago EFI Sas Driver unhealthy status reported" error. Following the prompt shows "L2/L3 Cache Error" has me input an 'X', and then nothing happens. If I click Finish and Save, it goes back to the boot enumeration screen and informs me a driver needs to be configured. I cannot get out of this loop. I see someone suggest doing the input entry through the LCC/Bios, but I cannot get into those with the card installed. iDrac showed the controller at first but it seemed to be inaccurate as it would show the drives even if they were removed. After removing the card the first time it says there is no out of band controller available when reinstalled. I cannot access any of the boot options (F2, F10, F11 for USB) while the H330 is in the machine. If I remove it all work fine. All cables and connections have been checked. all drives have been taken out and put back in without change. All harddrive bays show a solid green light when a drive is inside.  I have tested multiple Bios options such as boot settings (which the machine does not make it far enough to use), Bios update, LCC update, and have a H330 firmware update but cannot apply it because the machine refuses to boot with the card in.  Should I be looking at acquiring a new H330 card at this point? 
T430 - Avago EFI SAS Driver, cannot pass to access most suggested fixes.
