[RESOLVED(ish)] Multiple Br10i/lsi1068e in one system?
Has anyone had any luck running two lsi1068e based (Br10i in particular) cards on one motherboard?
My Intel BX38BT will only recognize one at a time. I've tried various FW/BIOS from various vendors with no luck.
My mobo has 3 PCIe slots. 2 x16, and one x4. I have my video card in the x4 slot, and the 2 SAS cards in the x16 slots. The bios shows both of the x16 slots negotiated to x8, so it sees the card, but only one shows up during post and detects drives. Disabling boot rom on them makes no difference. If it's enabled, it'll only scan the first controller (HAB0, the one with the lower PCI ID) and ignore the second one. Swapping slots around with video card makes no difference.
One clue I found in the mobo manual is:
Desktop Board DX38BT provides the following expansion capability:
• Two PCI Express 2.0 x16 ports
• One PCI Express 1.1 x4 port (routed to a x16 connector)
Which leads me to believe that maybe I can only use 2 PCIe slots at a time? But if I put my Dell Perc5/i (lsi1068 chipset) in, then both show up, which kind of throws that theory out the window.
Nonetheless, I'm going to try to pick up a PCI video card & see what happens. I don't have another dual PCIe board to test on at the moment.
Sidenote: I have to put the cards in a different machine to access the setup BIOS. On mine it says entering setup, then just bypasses it. I've read that on some boards you have to invoke the one time boot screen to be able to get into the SAS BIOS, but that has done nothing for me.
Any way, thanks in advance for any feedback.
EDIT: Not likely to matter, but I'm running CentOS 6, and lspci only shows one SAS card. No mptsas/SCSI errors in dmesg.
