I am having a real issue. I have two SATA 16Tb hard drives in the back of my HPE DL380 Gen9. I am running 12 6TB SAS HDs in the front plane in 1=0 raid with a P840 card.

I have tried adding the drives with the native SATA controllers, I have tried adding them through thep840, I have added raid 0 on the drives (I really don't want to do that If I can avoid it).

The best that has happened to this point is I will add the directory and the drive immediately disappears as soon as I try and send a backup.
A lot of the time I get errors similar to this:

# /sbin/sgdisk -n1 -t1:8300 /dev/sdb
Creating new GPT entries in memory.
The operation has completed successfully.
# /sbin/mkfs -t ext4 /dev/sdb1

I was convinced it was AHCI for a bit, but I'm less so now. I'm at a loss. I have tried everything I can find, and nothing seems to do the trick. The second error is interesting, but I haven't figured it out yet. Any thoughts?

Well, I think i solved it. It wasn't code, and it wasn't the hard drives. I have G10 3LFF backplane kicking around and after looking at it, I realized that it would fit on the G9, with a bit of compromise. Only one screw fits, but there is a lock that pretty much makes up for that. I swapped out the backplane, and it seems to be rock solid now. I'm running a backup to test it, but I think we are good. So if you are having issues where you cannot get drives to stay showing in the OS the minute you try and write to them, look at your backplane. I'll put it under the microscope and see if there is any obvious damage to the components. I don't see anything at the moment, but there must be something wrong. Anyway, problem solved.
