Hey all,
My first time posting so I hope I've done everything right..!
I recently got some 6TB "Enterprise Capacity" Samsung SAS (They're
marked 'Enterprise Capacity 2.5 HDD v4') drives pulled from some devices
from work that have been decommissioned and I've been trying to set them
up on my home server.
I have an SAS9211-8i controller with a SATA/SAS backplane that they're
connected to.
I'm getting these errors (it's the same for all of them but just showing
dmesg

Hmm, not sure what LA Check means, perhaps logical address.

I can see it's connected to the SAS controller properly (it's

I did some searching and some suggested they might've been set to 520
byte sectors if they came from a NetApp device but I can confirm they're
not (or I believe what's reported below is confirming it)
diskinfo -v /dev/da3
/dev/da3
512 # sectorsize
6001175126016 # mediasize in bytes (5.5T)
11721045168 # mediasize in sectors
4096 # stripesize
0 # stripeoffset
729601 # Cylinders according to firmware.
255 # Heads according to firmware.
63 # Sectors according to firmware.
SEAGATE DKS2F-H6R0SS # Disk descr.
Z4D47M960000R630UXCC # Disk ident.
mps0 # Attachment

Yep, you've got 512 byte sectors, so that isn't the problem.

I've been able to find very little info on the specific error "LA Check
Failed". I looked a /usr/src/sys/cam/scsi/scsi_all.c and honestly that
doesn't help me at all (I'll admit I'm more 'admin' than 'developer'
too) and it appears to be a Seagate specific error but otherwise I'm lost.
Any help would be most appreciated!

Well, one thing to try, since you can't write to it anyway, is formatting
it.

You can do it with camcontrol format or if you install sg3_utils you can do
it with sg_format.

If that doesn't work, you can try getting the log pages and smart data off
the drive to see if there is anything interesting.

If you install sg3_utils, you can do:

sg_logs -a /dev/da3

And if you install smartmontools:

smartctl -a /dev/da3

Those might give you a hint about what is going on.
