RAID card can't see hard drives...

Featured Replies

Hello everyone.  I just (almost) finished my first server build.  What I have:

 

Norco 4224 Case

 

SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

 

Supermicro X9SCM-F-O Mother board

 

Xeon E3-1230 V2 Ivy Bridge 3.3GHz (3.7GHz Turbo) 4 x 256KB L2 Cache 8MB L3 Cache LGA 1155 69W Server Processor

 

Kingston 16GB (2 x 8GB) 240-Pin DDR3 SDRAM ECC Unbuffered DDR3 1333 Server Memory

 

2 x SUPERMICRO AOC-SASLP-MV8 PCI-Express x4 Low Profile SAS RAID Controller

 

1 x SATA2 PCI Express Raid Card

 

NORCO C-SFF8087-4S Discrete to SFF-8087 (Reverse breakout) Cable

 

I am able to get everything to boot up and I can see all hard drives that are connected directly to the SATA ports on the motorboard and/or the SATA2 PCI Express card.  I cannot see any hard drives connected to the SuperMICRO Raid controllers.  I went into the BIOS and I can see both cards but they don't see any hard drives.  After trolling the forums and web, I messed with the BIOS a bit but then saw some posts about reverse/forward breakout cables.  I'm thinking maybe thats my problem but don't know...  Thanks for the help!

By the way, my Norco 4224 came with SATA connectors on the backplanes...  I saw that the one from NewEgg comes with SAS connectors.

They are not RAID cards, they are HBAs. They should definitely see the connected drives.

 

A few things come to mind. The SAS connectors must plug securely into the cards. It is somewhat easy to insert them, thinking they ate fully inserted, but they are not. If double check that.

 

If secured, I'd ask what type of connector cables are you using. With the Norco and those HBAs I think you'd use SAS to SAS connectors. But if you are using SAS to SATA cables, there are two types, one meant to split the signal from the SAS connector to the 4 SATA ports (breakout cable) and one meant to combine 4 SATA port signals into a SAS connector (reverse breakout cable). They look the same but are not interchangeable.

I believe you would need forward breakout cables to connect the HBAs to the Norco backplane. But Norco's with SAS backplanes typically need the reverse breakouts to connect motherboard ports to the SAS backplane.

Thank you.  This was the path I was headed.  I'll double check the connections tonight, first.  Then I'll order new "forward" breakout cables.
