I have a RHEL 5 image for a Dell Power Edge R515 Server with 2 300 GB SAS drives. I need to clone that image onto another R515 that has 2 500 GB SATA drives. Will the drivers for the SAS interfere? Is this even doable?
If your RHEL 5 already has the required kernel modules for the SAS device. I believe it's doable.
Therefore make sure your kernel modules exist on the system, and also inside the initrd.
