SAS HDD not working in TrueNAS Build, even with compatible backplane

Good afternoon everyone,

I have a TrueNAS server in my homelab that has been running for quite some time, and it's due for an upgrade. I currently have a mix of 4 different SATA HDD in RAIDz2 configuration in a Supermicro 2U X8DT3. I checked before purchasing the new drives that the backplane is compatible with SAS and SATA drives on every port. I now have a bunch of Seagate Constellation ES 2TB drives, models ST2000NM0001 and ST3200044SS. I put some into my server, and instantly things got weird. Of the 12 drive bay, only slots 6-8 will recognize the drives, no matter the drive or model. In TrueNAS, the drives that are recognized fail a long smart test with "Error:48816477". I've been to the smart test wiki and can't find any error codes that match. Also, they all have errors when trying to wipe them "Error: [Errno 22] Invalid argument". I found this command online but it did not come with any instructions and I am hesitant to use it without understanding it completely "sysctl kern.geom.debugflags=16". My end goal with this is to replace my current pool with 4 old drives with a new pool with 10 new drives.

I would greatly appreciate any help or suggestions you all have! As a new computer science student, I haven't learned everything yet, and would really like to learn more about this system I am using and why it is not working as expected.

offtopic, end user question should be asked on Super User

Also, you talk of backplane and board ,but not cabling - and has TrueNas SAS drivers installed?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
