I have a review open to switch to mrsas(4) by default, for devices
supported by both it and mfi(4). mrsas(4) should be better supported

https://reviews.freebsd.org/D45476 mfi: default to using mrsas(4) for
newer cards
However, we have a report of volume corruption with the IBM ServeRAID
M5110e when used with the mrsas driver:
PR196820 IBM x3650, ServeRAID M5110e, volumes corrupted after boot
with mrsas driver
Clearly we do not want to corrupt users' RAID volumes, so I would like
to request feedback from mfi/mrsas users in general, and M5110e users
in particular.
Note that there may be a possibility of data corruption, so please
investigate only on test systems.
To test, set the loader tunable hw.mfi.mrsas_enable=1 in
/boot/loader.conf. Confirm that mrsas is being used, and that the
system functions properly.
I use Dell servers and i set the loader tuneable hw.mfi.mrsasa_enable=1
on these machines. I use ZFS, so no raid functionality off the card
itself. This works fine for me. I have not have any issues. I use this
setting as mrsas give me way nicer device names, i do remember having
boot issues with the mfi default. But that is a long time ago.
