Not found: '/sys/class/sas_host/host4/device/port-4:3/end_device-4:3/target4:0:3/4:0:3:0/scsi_generic/*[0-9]' about sasutils HOT 3 OPEN

On Arch Linux I experienced the same behaviour, I also had to manually load the kernel module there.

I really hope it's not NixOS-specific 😅 but I ran into the same when I didn't have the sg kernel module loaded (also on NixOS). modprobe sg or boot.kernelModules = [ "sg" ]; should do it.

Do other distros automatically load sg when running on supported hardware? Or does the sg3_utils package cause it to be loaded?

In any case, the error message could be improved IMHO, especially since /sys/class/sas_host/ could also be absent on machines without SAS.

I can confirm it works after loading the kernel module. I also think that the error message should be improved.
