DB2 DPF and High Availability - Are they compatible in word and concept? This is what I mean...

Dear DB2 DPF/High Availability experts,

I was having a technical discussion with a colleague about DB2 DPF and in the course of our discussion I went into describing what I think of when DB2 DPF is mentioned. I think of high-availability, scalability, performance, etc. But my colleague seem to insist that one does not talk about DB2 DPF and high availability in the same breath/sentence. What he is saying to me is that with high availability, you are talking about DB2 failover (we use HACMP deployment). In other words, DB2 DPF is one thing and DB2 high availability is another.
Is this a correct way to look at this two DB2 deployment setup?

Please help clear up this point for me and my friend.

Thanks
