SAS3408 driver problem

[Andrew Bell]

I have a server with a SAS3004 controller and 2 SAS3408 controllers. When I boot FreeNAS 11.2, this happens:

root@fred[~]# lspci | grep -i raid
1b:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID Tri-Mode SAS3408 (rev 01)
65:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS-3 3008 [Fury] (rev 02)
b3:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID Tri-Mode SAS3408 (rev 01)

root@fred[~]# dmesg -a | grep -i raid
pci7: <mass storage, RAID> at device 0.0 (no driver attached)
AVAGO MegaRAID SAS FreeBSD mrsas driver version: 06.712.04.00-fbsd
pci11: <mass storage, RAID> at device 0.0 (no driver attached)

I want to try to prevent the 3004 from loading the mrsas driver and have it use the mpr driver instead, and see if the mpr driver will then load the 3408s. But I have no idea how to do that.

Anyone have a suggestion?

Theoretically, based on the information here: https://www.freebsd.org/relnotes/11-STABLE/hardware/support.html#disk
This should be possible, but you must understand that FreeNAS is an appliance that is built from select components of the FreeBSD operating system.
It may be necessary for you to submit a ticket with the developer to get this feature added.

The 3004 wouldn't cause mrsas to be loaded unless it was in RAID mode. Crossflash it to IT mode and try again.
