This is a known issue with Dell HDD firmware. You need to disable power
management in sd, like so:

 1) first determine your drive vendor + product IDs:

echo "::walk sd_state | ::grep '.!=0' | ::print struct sd_lun un_sd | \
  ::print struct scsi_device sd_inq | ::print struct scsi_inquiry \
  inq_vid inq_pid" | mdb -k

 2) then enter the vendor ID + product ID into /kernel/drv/sd.conf like
    so:

sd-config-list = "VENDORID PRODUCTID", "power-condition:false";

For instance, in my case I'm getting in step 1)
inq_vid = [ "SEAGATE " ]
inq_pid = [ "ST2000NM0001    " ]
inq_vid = [ "SEAGATE " ]
inq_pid = [ "ST3300657SS     " ]
...

So my sd.conf looks like this:

sd-config-list = "SEAGATE ST3300657SS", "power-condition:false",
                 "SEAGATE ST2000NM0001", "power-condition:false";

After that just reboot and you should be good to go.

Cheers,
