Hi Folks... To those who might have more experience with these boards than I do - is there a way to have them re-read the bus and export anything new (or remove anything "not new") from the driver configuration? I can't figure out a way to do it as of yet - the 3Ware drivers automatically export new units without a reboot, but it appears the system has to be downed and reset for configuration changes to show "through" to FreeBSD on the Areca drivers. -- Karl

If you're talking about creating RAID sets and such, I believe that areca-cli (ports/sysutils/areca-cli) will push changes from its rsf and vsf commands up to FreeBSD. you'd probably need to do a 'camcontrol rescan all' after making changes through the CLI utility.
