March 25, 201610 yr So I just noticed one of my UnRaid servers is perpetually spitting out these logs which I don't understand because I don't have an sdo or sdi drive in my system. Diags attached.

Only think I can think of is that the drives appeared to go offline and come back online as a different device id?
