The sense data in the screen shot boils down to an ASC/ASCQ pair of
0x35/0x05. Looking this up in the ASC table found at t10.org gives
the following:
35h/05h ENCLOSURE SERVICES CHECKSUM ERROR
What this basically means is that the disk enclosure that you're using
has some sort of an unknown defect or failure. It has nothing to do
with the OS. Dell needs to send you a new enclosure, plain and simple.

Thats why I have only hope here with FreeBSD List...
I've CC'd Scott Long, who is the author of the mfi(4) driver. He should
be able to explain what the error messages mean.
Scott, check out the URL below.

If it looks healthy, why there are these errors on the screen? Is it
controller problem or disk?
SCSI normally reports 3 things when it encounters an error (particularly
disk errors): Sense Key (SK), Additional Sense Code (ASC), and
Additional Sense Code Qualifier (ASCQ).
What appears in the below screenshot is a large amount of sense data,
but I can't make heads or tails out of it, because it's written in a
driver-centric manner ("Encl PD" means nothing to me). I can read part
of the CDB data, but it doesn't tell me much. Scott Long might know.

You should try asking the system manufacturer if they know what any
of the data means.
