My guess is that the nvram of the bios somehow reset its configuration back to default. (corruption, power loss, etc. - these are cheap parts made with failure rates after all)
The default of most x86 bioses up until the last few years was to bring up SATA ports in IDE compatible mode, which will have them show up as wd devices. The ports can be reconfigured into something commonly called AHCI mode, at which point OpenBSD will see the ports as sd devices. Fortunately, either mode will work without any major issues, but I will say AHCI is commonly the faster choice on any given platform. > On Oct 30, 2020, at 1:24 PM, Amelia A Lewis <[email protected]> wrote: > > Heylas again, > > So, I have a working machine again, after copying a kernel over from a > working machine, verifying it, and generating a new hash (I have a > whole long saga of investigation, but I'll spare you). > > Can anyone suggest why a machine, with no activity but ssh logins and > then a syspatch of patches 2-3 on 6.8 would spontaneously start > considering the SATA disks in the machine (which were previously loaded > as sd0-sd2) as IDE (wd0-wd2)?
