In full panic mode right now. Both of my parity drives are disabled. In the SMART report I can see

 

Smartctl open device: /dev/sds failed: No such device

 

in dmesg I see

I can't spin up the drive (expected). Server has been running fine until today. I want to power it down and check the cabling, see if the drives come back on reboot, but before that is there anything else I should do? (diagnostic report attached)

Also issues with disk4, looks more like a power/connection issue, check cables, also any splitters, could also be a PSU issue.
