I used for a while the combination of SCSI (3 hard drives) and a PATA data drive. (reason for this set up was large scsi drives being difficult to get) It for most part was not satisfactory, the Linux kernel having some kind of built in bias far PATA. For instance when uodating the kernel with lilo one had to unplug the PATA otherwise the lilo command would fail.
That's probably a BIOS bias. Lilo calls the real mode BIOS to get some information on how boot should work.
On a UUID enabled system (before I changed it back to using device's) I swapped a pair disks between devices. On reboot system failed as it could not mount the drives. I had assumed according to the UUID docs that the drives would be mounted according to UUID to mount point mapping given in fstab, this did not occur.
Mounting the root filesystem is determined by the initrd/initramfs in conjunction with the kernel command-link (from the boot loader). Data from /etc/fstab should be used in configuring the boot loader and/or setting up the initrd/initramfs. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
