Boot device original /dev/sda1, it still /dev/sdc1 NO change. Modify modprobe.conf to list the disk driver you want loaded in the order you want then re-make the initrd file: For example, say you want your internal SATA disks recognized before your SAS RAID disks, your modprobe for the scsi_hostadapter would look something like this: alias scsi_hostadapter ata_piix (or ahci, sata_XXX whatever your SATA controller is) alias scsi_hostadapter0 megaraid_sas Then you remake your initrd with a command: mkinitrd -f /boot/initrd-$(uname -r).img $(uname -r) Remember to use LABELs or UUIDs in fstab first or your partitions won't mount (wrong disk names)! Then reboot. -Ross
