Change order of SCSI devices (/dev/sdN)?

[Toralf Lund]

One of our customers has a server where the internal system disk is connected via an on-board SCSI on the motherboard while external disks are connected to a PCI-based SCSI host adapter.

Now, the BIOS on this motherboard will return the on-board controller after the PCI one(s), so the system disk will be the last SCSI device, and thus seen from Linux becomes /dev/sdb if there is one external disk (/dev/sda), /dev/sdc if there are two and so on. This makes the setup quite messy, and also means there is trouble booting with one of the external disks switched off as the boot disk device id will then change.

Is there a way I can change the device id assignment order so that the system id. is constant? Simple reversal of the order (i.e. _last_ disk as /dev/sda) would do just fine.
