Hi all,
First, I'm not fluently speaking SCSI nor kernel-c, so please don't byte
too hard if I'm missing something obvious :)
I tried some thing before posting here, from testing the hardware under
linux (it work flawlessly there) and vendor's tests software, changing
the adapter (for a different one, but with same chipset, that's all I
have), upgrading firmwares where available (card and dell enclosure),
trying to read mpr(4)'s code=E2=80=A6 well this is beyond my knowledge.
Hardware: dell PowerEgde R430 with an LSI SAS3008 card and an MD1420
enclosure with 24 2T Seagate sas drives.
This machine also have an embedded SAS3008 (dell perc H330) in non-raid
mode (mrsas driver) with 4 SSD drives to be used as ZFS cache/log=E2=80=A6=
System: FreeBSD 11.0-RELEASE-p3
Please tell me if there are tests I could do, patches to try, or ?
Currently compiling 11-STABLE kernel with sys/dev/mpr from CURRENT, but
with no clues=E2=80=A6
