Status on LSI SAS2008?

[Tanel Rebane]

Hello,

Does anyone know the status of the LSI SAS2008 chipset in regards to FreeBSD? If any, I suppose it�s the mfi(4)-driver that should pick up support. I know the LSI SAS2108 should work fine with mfi(4) but I have no idea how big the differences between 2008 and 2108 are.

All feedback is valued, thanks in advance!

Best regards,
Tanel Rebane

Hi all,

I've been running those cards on Linux.

The 2008-Chip is an HBA-Chip. Linux uses the mpt2sas Driver (the old
HBAs are using mptsas).

The 2108 is the Raid-Chip using the megaraid_sas or 3w-sas driver
(depending on the firmware installed- LSI 9261-8i and 3ware 9750-8i seem
to have identical Hardware.

Regards,
Michael!

Hi,

Can you please clarify which linux works and how large the individual
disks are?

My problem under BSD is 2-fold:

1. There is an open PR for this LSI device at
http://www.freebsd.org/cgi/query-pr.cgi?pr=144326

2. My smallest disk is 2TB

Without visiting the datacentre, I have no device to install to.

thanks!

I know that 6GBIT SAS HBAs with LSI 2008 Chip are in the default kernel
since 2.6.33- patches are available. The Disksize shouldn't matter.

you should reclassify the pr- telling about the exact device (device/
vendor id).

is this a problem? When you have a driver, it is recognized.

Your largest disk is probably also 2TB ;)

even when visiting the DC, I suppose.

I know of some 3GBit HBAs beeing able to be upgraded to Raidcontrollers
(linux driver changes from mptsas to megaraid_sas). But this is not
possible with all LSI devices.

Afaik we don't have a driver for freebsd yet.
