The log files show that there's something wrong with /dev/da1 (unrecovered data error; you should check whether you have ARRE and AWRE set), but that shouldn't cause the system to hang up. I'd strongly doubt that the problem has anything to do with the host adapter. I don't know of anything in Vinum which would cause these problems either, so we'd really need to know more details. Sorry I can't give you any more ideas, but there's not much to go on. > What problems are you having? Using lftp, I was in the midst of > ftping a 50 MB or so file to the raid directly.
