To be honest theres very little interaction with the O/S - if a drive fails, the array beeps constantly until sorted out. If you have a hot-spare it will automatically start rebuilding to that, otherwise you have to down the machine - and run the DOS utilities...

We have had no problems with the DPT, it was cheap - it's cheerful, and it does what we want... I beleive Simon Shapiro (who wrote the drivers) is also working on FreeBSD utilities to control the rebuilds / array config etc. Regards, Karl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
