The reason is DELL R900 internal RAID and external RAID use same driver. There is NO way to change adapter sequence on /etc/modprobe.conf. Is there some *specific* reason you want the device names in /dev to match some sequence? For mounting to work, you can just use UUIDs or LABELs in /etc/fstab. This also works for swap partitions (mkswap has a -L option). The only other reason would be getting the BIOS to boot the correct disk (and this would be handled by BIOS settings). I am not sure what grub needs exactly (I use lilo myself). Otherwise, why *exactly* does it matter if a certain disk's device file is named /dev/sda1 or /dev/sdc1? -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller at deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/
