(Moved to the freebsd-scsi list) As Joe Karthauser wrote: > Is it possible to reprobe the scsi bus after a reboot for allow for > drive swapping? I guess that there must be some support for that in > there somewhere. There's ``scsi -r'', though it used to be horribly broken for quite some time. It worked fine in FreeBSD 1.1.5.1, and started to be ok again in -current of not too long ago (about a month or two). _However_, drive _swapping_ is probably unsupported. I think the sd driver gets royally screwed if you exchange the drive that was present at boot time by one with another total number of blocks later. Even the `od' driver (that is supposed to catch up with such situations) doesn't do it right now, but there's a patch pending in one of the PRs that allows for it. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
