I have 2 so called internal sata drives and 2 3ware 9550SX controllers (both have one raid-volume). So when debian Sarge is started up, I have 4 /dev/sd? disk. The problem is, that device names is changing. At first /dev/sda,b is internal drives, then after restart could be, that /dev/sda,d is RAIDs (on 3ware controllers) and /dev/sdb,c is internal drives. Can I somehow force things, that device names wouldn't be changed? Tanel
