MegaRAID 9271 hangs on boot

Hi all,

Our server had been running fine for approximately 2 months, when the raid 10 drive disappeared from Windows (Server 2012 R2 x64). Upon reboot, the computer would get through the MegaRaid BIOS, which sees all 4 drives as well as the virtual drive, then hang. If left for awhile it would eventually go to the Windows boot, which would also take a long time to startup. Once back in Windows, the virtual drive is not in disk manager, and the raid card says "I/O adapter hardware error has occurred" in device manager.

However, unplugging the mini-SAS cable from the raid card, the systems boots as normal and the card shows up fine in device manager.

Updated to firmware version 23.32.0-0009 with the same results. Tried with a second MegaRaid 9271-4i, and it worked perfectly as normal, all data in the raid intact! However, an hour later, virtual drive disappears from Windows and back to the same situation as the first card.

Tried swapping PCI-e slots, running with no other PCI-e cards (ie. video card) with no change. We've even been running it with an extra CPU fan blowing across the heatsink keeping the temp down to ~38C.

Hardware specs:
LSI MegaRaid 9271-4i
Supermicro X10SAE motherboard
4x Western Digital SE WD4000F9YZ in Raid 10 config

Let me know if any other information is needed, and hopefully someone has a fix!
Thanks

  1. Try disabling the onboard sata controllers one at a time to see if there's an incompatibility with either the intel c226 or the asm1061.

    Thanks for the reply. I just tried disabling one, then the other, then both, all to no avail.
  3. There goes that idea...

    Checked with WD and they say that drive is not compatible with that controller.
    Heres the supported controllers and firmware levels needed pdf:

  4. Rather simple thing to try, just to rule out. Try removing your CMOS battery for 30+ seconds. You might just need to reset the BIOS

    Thanks for the replies, issue seems to have been resolved.

    While WD doesn't list the drives/card being compatible, LSI does. So I went looking at other bits.

    Picked up http://www.newegg.ca/Product/Product.aspx?Item=N82E16816115064 just to see if a different mini-sas/sata cable would do anything. Turns out, it did! The cable that came from LSI in the kit turned out to be the weak link making everything else stop working.
