SAS Drives on T7600 (No RAID)

Question

HI,

I'm experiencing a strange issue with my T7600.

I'm using SAS drives (6Gbps). During Win 10 x64, the 7600 doesn't detect the Raid controller, so I load drivers from my USB and the installation starts fine.

I install drivers, programs.... all is working. I even restart the machine when asked, and all is fine.

After about 2 hours of machine preparation, I restart and I get message saying: No bootable devices!

First time, I suspected the SAS drive, I changed it. But after long preparation hours, I got the same error.

Any one can help me on solving this issue?

Thanks a lot.

Hi,

The problem comes from inequation between SAS drives (witch are 6Gbps) and the integrated SAS controller limited to 3 Gbps. I installed the Perc H730 (6Gbps capable) and now drives work nicely: I putted 4 SAS drives 6Gbps (2 SAS + 2 SSD SAS) and all are working.

Thanks a lot.

I suspect that Windows updates may have installed an incompatible or corrupted driver causing issue to storage controller. It could be a (known) bad chipset driver.

By saying after long preparation hours, did you mean running Windows update? You can repeat the installation process again and when running Windows update, watch for anything related to storage controller driver or chipset. Do not run that driver update, instead, download the same driver from Dell website and manually installing it. After that, Windows update should bypass that driver and hopefully avoiding the issue from repeating.
