LSI MegaRAID 9260-8i not showing up... Anywhere!

Recommended Posts

Hello all!

I'm new here and this is my first post. I've been searching for a possible reason why this RAID controller I purchased isn't showing up in the new server I'm building.

Its a pretty straight forward setup. Supermicro X11SSH-LN4F motherboard with Xeon E3-1230v5 and 64GB RAM. Samsung 950 PRO M.2 SSD boot drive and eight 6TB WD Red hard disks.

I originally purchased this motherboard because it supports 8 drives in RAID. I quickly found out that in RAID5 the Intel PCH crumbles. Write throughput sits around 25 Mbps max. So That's why I've turned to hardware RAID. Plus I would like to use RAID6.

Anyway, I've tried changing to slot from LEGACY to EFI. I've tried both slots capable of PCIe 8x. Nothing... Nothing in POST. Nothing in BIOS. In fact BIOS reports the slot empty.

So aside from a dead card, is there anything else that would cause this?

Tried the card in a different motherboard just to make sure it's good?

I'm going to do that in the morning... I'm also going to try a different card in the new motherboard because I'm suspicious that the power bus may have died on it.

I will follow up as soon as I have more info.

Have you tried inserting the card withOUT cabling any drives?

Sometimes the INT13 Interrupt is enabled, and this has been

known to interfere with the chipset's on-board ports.

With less expensive RAID controllers, we typically install

it first withOUT any cabling attached. Then, we DISABLE INT13

to allow the chipset's on-board ports to function normally.

At the right moment, we then flash the card's BIOS and

during that step we ENABLE INT13 and then re-boot

into the BIOS to choose that "device" as the primary

BOOT DEVICE.

Another permutation is that INT13 can have the effect

of DISABLING the chipset's on-board ports if they are

configured in the BIOS as "RAID" mode.

Safest test is to downgrade the storage mode to "IDE"

in order to test whether or not the card shows

up as a "bootable" device in the BIOS.

Another permutation is to try setting the storage mode

to "AHCI", but that mode may not be "native" to the

chipset and consequently will require the installation

of the AHCI device driver.

The latter is why one key test is to downgrade the

storage mode to "IDE" in order to determine if the

BIOS detects the UNcabled card as "bootable" or not.

BEST WAY to determine if the card is recognized, or not,

is to install it in a PCIe slot withOUT cabling, then

boot into the BIOS to see if the BIOS sees the card:

If INT13 is ENABLED, the BIOS should recognize the

card as a "bootable" device.

If INT13 is DISABLED, the BIOS should not see the card

as a "bootable" device.

If the INT13 setting makes no difference whatsoever,

regardless of the storage mode setting (e.g. IDE / AHCI / RAID),

you should contact the manufacturer's Tech Support.

Hope this helps.

Ok. Pardon my ignorance but I don't know what INT13 is.

What I've done is completely disabled the internal SATA/RAID controller (my boot drive is an M.2 PCIe 3 SSD) and I still don't see the card. I've tried it in 4 different systems. 3 Intel and 1 AMD. Nothing....

I don't want to boot from it, I just want to use it for media storage. So I was hoping it would just show up as an unknown device in device manager and I would load the driver and be done with it...

> I don't know what INT13 is

INT13 is "Interrupt 13".

Based on my experience with Highpoint RAID cards,

It's a settling in the BIOS of some add-in cards that

tells the motherboard BIOS that the OS is bootable

from storage devices wired to that card.

If it's ENABLED, it has been known to disable

the RAID functionality of Intel chipsets,

requiring the storage mode to be downgraded

to "IDE" or "AHCI" i.e. NOT "RAID".

> I just want to use it for media storage

Just thinking out loud here: if INT13 is ENABLED,

it may need to be DISABLED if you do NOT want

to BOOT from that card and if you only want to use it

for media storage.

Ok. Well I'm waiting for my new RAM to be delivered. As soon as I get it I'll take a look and see if I can find it in BIOS.

I received the new RAM and a new LSI 9271-8i. Installed both and powered up. The new 9271 immediately showed up in POST. So the original "open box" 9260 was indeed DOA.

It cost me 3x more but in the end it's a more up to date controller and it works.
