SCSI Drives "Stealing" OS's boot device

By cp409sd ·
When I connect a StorEdge 3320 array of disks (in a JBOD configuration - no RAID, the OS just sees them as disks) to a RHEL 4.3 system, linux will assign /dev devices to it. The only problem is that it assigns the /dev/sda1 device (the root partition) to a disk in the array, instead of the internal disk.

I found that Sun knows about this issue and says the following:
1.During boot up, press 'e' at the grub kernel selection screen.
2.Go to the line that points to the kernel and press 'e' again to edit the line:
kernel /vmlinux-2.4.9-3.24 ro root=/dev/sda3
3.If one drive was added to the system, change /dev/sda3 to /dev/sdb3. For two new drives, change it to /dev/sdc3.

I'm sure this would work, except that I am using Linux LVM for all partitions, besides /boot of course. Any ideas? Is there a way to statically map LVM partitions? Thanks.
