RE: List of SAS controllers

Thanks Silas

I will enable write cache. The controller has software raid, and that why I
was told it does not support write cache through BIOS..

I will enable this and give it a try.


Either way is there a list of netbsd supported SAS hardware controllers as I
don't see them under http://www.netbsd.org/support/hardware/pci.html unless
i am looking at the wrong place.

In a server, I have a 1064E:

    $ dmesg | grep mpt0 | head -n 2
    mpt0 at pci2 dev 0 function 0: Symbios Logic SAS1064E
    mpt0: interrupting at ioapic0 pin 16, event channel 3

Since this patch...

http://mail-index.netbsd.org/tech-kern/2007/07/26/0022.html

... NetBSD 5.0 seems to recognize my SAS controller, although it can't
enable write cache. Since at that time (when 5.0 was released) 5.0
couldn't enable it (don't know about nowadays...), I following OpenBSD
people workaround:

http://marc.info/?t=118443450500010&r=1&w=2

They recommended me to install Linux, enable the write cache and save
its configuration back to the controller, and install back NetBSD. It
worked, but it would be very cool if NetBSD supported it.
