Ever since I upgraded to v5 from v4.7, my Supermicro AOC-SASLP-MV8 periodically dies during parity checks (all drives on it go off-line). I re-seated it and checked all power cables, however, I continue to have the problem. Re-booting the server is the only solution to getting it going again. I saw several complaints on NewEgg that others have have experienced similar problems with the card while under a load.

 

Does the AOC-SAS2LP-MV8 have similar issues? If it doesn't have these problems, can I merely shut down my server and swap the two cards? If it, too, is problematic, is there a similar card out there that will work in place of the AOC-SASLP-MV8?

What's the temp during a parity check?

28-32c

 

I have 2 AOC-SASLP-MV8 in my system.  I used to get this when doing a parity check.  I found at that despite me having checked many times it WAS a seating problem with the board.   

 

What I found was that when I tightened the retaining screw on the back faceplate it was tending to slightly lift one end of the board connector.  This was not enough to stop the board working on boot-up but did mean it was likely to fail under sustained load.  Just thought I would mention it as it was not easy to spot without a VERY careful look at how the board was seated when I pushed it in initially (without the screw) and how it ended up when screwed in.

Thanks for the tip re the retaining screw. I noticed the same thing on my board (and Norco case). I'll re-seat it again and permanently remove the screw. Although this sounds like very plausible cause of the problem, it doesn't entirely explain why I began having this problem after installing v5. This NEVER occurred during the couple of years that I ran the same board full of drives with v4.7. Perhaps I slightly jiggled the board when removing my thumb drive to upgrade to v5 - although I certainly don't recall anything out of the ordinary. Nonetheless, I'll check it out.

 

Thanks again for the tip.
