I don't believe it's enough to compare the chip names (SAS2008, SAS2108, = etc.). The mps driver advertises support for a list of SAS2108 devices, = but the SAS2108 chips I have access to (in MegaRAID SAS9261-8i = controllers) report PCI IDs that are only supported by MFI. My discussions with LSI support led me to believe that the claim of 2108 = support in mps is incorrect but I've never confirmed that with anyone = here. -Andrew On Mar 2, 2011, at 12:36 PM, Erich Weiler wrote: >> I guess it would be most useful if I could somehow force MFI to be = used on my boot disk as it is now, but use MPS on my 24 JBOD disks = coming from the Perc H800 SAS controller...?

What gives? ;) Is = it that the MPS driver *and* the MFI driver both support the LSI SAS2108 = chipset, but the MFI driver checks first during boot, so it wins? > _______________________________________________ > freebsd-scsi@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-scsi > To unsubscribe, send any mail to = "freebsd-scsi-unsubscribe@freebsd.org" -------------------------------------------------- Andrew Boyer aboyer@averesystems.com
