Does anyone know how to get an HGST Ultrastar SN200 series device out of diagnostic mode?
I did a longer write-up of my troubleshooting journey over on the Proxmox forums, but I think I know the problem now and STH seems to be more familiar with the SN200 series. I have had six of these devices working beautifully for more than a year, but when I moved them to a new server, shutting down the server reliably borks the devices and sets them into diagnostic mode. This happened to two of my NVMe drives, then while troubleshooting I swapped in two working devices. So the casualty count is currently 4/6. The remaining two are working just fine another server, but I'd *really* love to get these four devices back online, since they seem to be passing all the health checks.
It appears that the devices are not being shut down correctly. On firtst boot the devices show up fine and I can partition / store data/ etc. However, on first shutdown, I captured the following photograph as the server was shutting down:
The devices also appear to be diagnostic mode, as I connected them to a Windows host, install Hitachi Drive Manager (hdm) and started poking around:
