Hi All,

Just bought 2 Seagate Exos X16 10TB SAS drives for my home server running through an LSI 9300 16i HBA.

I flashed the correct firmware onto the 9300, as I want to create a ZFS pool and need IT mode. It seems to be working correctly, it is detected in proxmox and I can map the resource. However, the drives are showing up as 0B in lsblk, and I am unable to find where else they would be. I can lsblk -o NAME,SIZE,MODEL and see:
NAME SIZE MODEL
sda 0B ST10000NM002G
sdb 0B ST10000NM002G

Smart CTL seems to be gltiching, makes me think hardware issue.
sda:

I tried using SeaChest (seagates recovery software) to both make sure the firmware is ok and format the drive properly. However I got "Drive not ready" error on almost every command I ran. Seems to be some sort of OEM lock, but I am not 100% sure. I also tried the drives/controller on my main pc, same situation.

Any ideas? Faulty drives? Did I screw something up?
 
Welcome, @consumebees
If you command
sg_start --start /dev/sda
sg_start --start /dev/sdb
(possibly with additional options (see man sg_start))
do the drives and smartctl behave better?

If your system has no sg_start then install sg3-utils package.
