I have been using a pair of LSI branded 9420-8si cards in my backup
server on RELENG_10 since November 2014 (firmware from Oct 2014 off the
LSI site) and so far so good. However, a number of other users have
warned me not to use the mfi driver, and stick with the MPS driver and
some older versions of the firmware aimed at an IBM m1015. I use the
cards for zfs and to expose the disks individually through cam with the
mfip module and so far so good.
However, folks over on the FreeNAS forum are convinced I am flirting
with data loss using the supposed disastrous mfi driver/firmware combo.
Can anyone shed light on the state of these cards and how best to use
them ? I havent really seen anything on the FreeBSD lists in the past
year indicating serious issues, but then again, I only started using
these cards since Novmeber of last year.
I do zfs scrubs every month and they have yet to show errors on my 32TB
pool. (a number of raidz2s)
