OpenBSD disk devices prefixes

  • 772

Under OpenBSD, /dev/rsd0a means:

  • raw access
  • to the first, or root, slice (a)
  • of the first (0) SCSI (sd) disk

r says that the device is accessed in raw, character mode instead of the standard block access. Are there other known special prefixes like this one, or is it the only one?

partition openbsd dev

  1. In a word, no. You could always have tried ls /dev/*sd0a to see what other device nodes existed. What other modes would you expect to have available?
