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
