btw, 3dm can tell about reallocated sector count on sas somehow, while smartctl
cannot, even on supported controller :(
Notice how the device type is "<31>"? The mfip driver masks off the SCSI
INQUIRY peripheral device type bits to prevent CAM from attached da* devices to the disks. See
sys/dev/mfi/mfi_cam.c, search for T_DIRECT. That confuses smartctl and prevents it from
displaying information like the Grown Defect List.
I added a local hack to smartctl to interpret a peripheral device type of 0x1f
(unknown or missing) to 0x0 (disk), but I don't think the hack is appropriate
for general consumption. What we need is better way for mfi and aac to block
CAM from attaching without corrupting the inquiry results
I can add hack to the sources with checking if underlying driver is mfi
(there are already some for buggy SAT fw implementation). It is probably
easiest way to do this. I just tested - firmware itself returns correct
(disk) status.
Of course in the feature its better to fix in mfi_cam to avoid such hacks.
