Hi Everyone,

 

i encountered a problem when switching migrating to a new chassis. I transfered all my hardware from a CoolerMaster Centurion 590 to a Norco 4220.

 

Everything fittet perfectly. In my old Tower the harddrives were cabeled by SATA (6*Onboard Gigabyte GA-MA78G-DS3H R2.0 http://www.gigabyte.de/products/product-page.aspx?pid=2931#ov, 6*SATA AOC-SASLP-MV8). Everything worked just fine.

 

Since i wanted to use the new backplanes i orderd 8087 to 8087 wiring and a second AOC-SASLP-MV8. I plugged the new SAS Card into the x4 Slot (1 Backplane connected with 4 Drives). The old SAS card remained in the 16x slot (2 Backplanes connected with 4 Drives each).

After restarting the 8 drives connected to the 16x slot were showing up on the unraid website. Four drives were missing. I wrote down the missing drives and switched the slots of the SAS Cards. Now the missing 4 HDDs reappeard. But the other drives were missing.

Both cards seem to work correctly. I tried one card by itself in the x4 slot. No drives were showing up.

 

Can anyone help me please. Is there any known issue with this Mainboard and dual controller? I'm using Unraid 5 Beta 14.

 

thx

Do the drives appear in BIOS?

Hi thx for the quick response.

 

When I plugin both SAS-Cards at the same time, the SAS-Cards recognize all 12 HDD drives (Looked it up in the Configuration Menu of the SAS-cards). Unraid only Shows the drives connected to the x16 Slot. The drives connected to the second SAS-Card Show up missing.

 

Should I upgrade unraid?

Well updating to unraid RC-11 did not work. Please can anyone look into the syslog and can give me some directions. SAS-Cards still detect all 12 drives.

Check for BIOS updates for the MB and the cards.

I don't know how related this is to your problem, but I have had a somewhat similar problem with a motherboard that looks and sounds almost exactly like yours (A slightly different model number - GA-MA785G-UD3H - but the same layout and the same slot configuration. I suspect it is the same board.

 

There seems to be some odd behavior that I've enountered that seemed to be an interaction between the Supermicro cards and the board. It doesn't sound like the same problem you've had but it's left me suspicious of how well the board plays with the Supermicro card - particularly in the x4 slot. (You can see the thread I'm speaking of here http://lime-technology.com/forum/index.php?topic=26391.0 if you want though I'm not sure it will help you.

 

What might help is to look at the firmware on your Supermicro card. There are two versions of the firmware (.15 and .21). I had different problems with each version, though the .15 firmware worked fine until I started to use drives larger than 2 TB.

 

I would first make sure you don't have different firmware versions on your two cards (.15 on one and .21 on the other.) If that's not the problem try installing whichever version of the firmware is NOT currently on your cards.

 

If you need either version I can post them for you via Dropbox.

It would be great if you could provide me both Versions since i can't download the firmware from their website.

 

There is some connection. I've experienced the same bootup pattern (timeout) once in a while since connecting the second supermicrocard.

 

Thx

Here are links to both versions of the firmware.

 

.15 Firmware: https://dl.dropbox.com/u/6577979/3.1.0.15n.zip

 

.21 Firmware https://dl.dropbox.com/u/6577979/Firmware_3.1.0.21.zip

 

In case you weren't aware, you'll need to create a DOS bootable flash drive to install either version. Here's a link to how to do it.

Please let me know when you've downloaded the files so I can remove them from my dropbox. Good luck.

Thx i downloaded the firmware and will install it as soon as i get home. Which firmware are you using now? SAS-Card / BIOS. Did you get both cards to work?

I had been using both cards with the .15 firmware for about two years without any problems at all. It was only when I started trying to use drives larger than 2 TB that I started having problems.

 

The odd thing that happened was (and it's only relevant if I'm using drives larger than 2 TB) that with the .15 firmware the card hangs during the post process when a >2 TB drive is attached to one of the two SAS connectors on the card in the x4 slot. Like you, it doesn't matter which card. The problem is slot dependent and then only one side of the card in that slot.

 

So I installed the .21 firmware. But if I use the .21 firmware it deals with the large drives just fine but the whole system hangs at a later part of the posting process when it apparently tries to install some RAID capabilities. So I've had to go back to the .15 firmware and live with the fact that some of my drive bays cannot use drives larger than 2 TB.

 

As to the motherboard BIOS, I'm using F4 which is the BIOS it came with. The only later one is labelled as beta and I haven't tried it.

 

I'm seriously considering a motherboard replacement as I may now be encountering another problem that may be partly or wholly related to the MB/Supermicro card combo on large drives. Not sure yet. Hope that helps.

 

Trank you so much.I discovered, that if both cards are plugged in it will Show the Firmware of the x16 Slot SAS-Card. Eventually i had two different firmwareversions (15/21). After updating both to Firmware 21 i experienced the System Freeze as well.

So i degraded both cards to Firmware 15 and everything worked like a charm.

 

Thank you so much for your directions.
