We had an IBM xSeries server that FreeBSD lost its ability to recognize the 39160 dual channel controller that we had 14 drives sitting on ... we moved the hardware to another, non-IBM machine (ie. my desktop), which all the hardware show'd up on, but, in the excitement, we didn't think to mark the cables as to which channel was which, and, of course, my desktop didn't have the appropriate /dev/vinum devices ... now, I notice(d) that the drives appear to store their own information internally, which the dumpconfig was able to show up ... if I had plugged the channels in wrong (ie. da0 -> da7, da7 -> d0), what would have happened had I run 'vinum start'? would it know to arrange the drives properly regardless, or would I risk screwin gmy file system? ::( To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
