Bare Metal Restore for RHEL 5.5 and TSM 6.x

Sorry if this isn't in the right place, newbie to the RHN. 

I have deployed some RHEL 5.5 x86_64 bit systems. I have identical hardware to be used for recovery purposes. 

What are my options for bare metal recovery? Searching around on the internet doesn't render many results other than folks asking for help, and people giving misleading information. (Welcome to the internet)

Any help is greatly appreciated.
