Once the BOND was setup, all I had to do was complete following the guide, the entire process only took 2 days to complete (because of my first time setting it up)
Of critical note, do not enable HA from within XenCenter (XenServer) as this disables HALizard.
Failover of a allocated VM between the host with six 1500GB drives + a 350GB C drive takes ~ two minutes, but it's complete live migration.
So you'd never know the system was moving if you were using it.
