The simplest approach is to share your configs, usually with a shared
filesystem or drbd if you must, then configure CARP or VRRP, and set up
heartbeat to start up the secondary when the primary fails.  This is far
more reliable than trying to juggle which tftp address to pass your pxe
clients, and is generalizable to other services.
