Sudden spike of errors in 12TB drives connected to SAS2308 controller

Hi,

I have issues with my 12TB Seagate IronWolf drives. I have two SAS2308 controllers in my system and had suddenly "lost" two of my 12 TB drives on the one controller. I reconnected them to the other controller and at first everything was fine, the total loss again. Reconnecting one of the drives to an on-board SATA port, where its now working and rebuilding the Array.

Any common issues with the SAS2308 controller and these drives? I am a little afraid. I am running 2 drives redundancy, but every rebuild takes >24h.

    Not that I'm aware of, but the diags are after a reboot, if it happens again, post new ones before.
