I'd like to add two things:
1. Many platforms require their clusterware to support their cluster 
filesystem. So, in many cases, if you want a cluster filesystem, you'll need 
their clusterware to support it. 
2. Some admins object to the way that Oracle Clusterware does fencing 
(STONITH). I think that some of the product pitches offered by the third-party 
clusterware vendors pick on this point as some sort of weakness in Oracle 
Clusterware. Regardless of anyone's opinion, some admins choose the third-party 
product because of this difference. 

Those plus what Niall mentioned are the only decent (well, #2 is up for debate 
as a "decent" reason...) reasons I've heard. The main count against using third 
party clusterware IMO is the additional complexity of adding more non-Oracle 
software to an already complex software stack.

Hi Niall

Well i really doubt these kind of reasons do work in
Multi-Million Dollar organisations where we need to be
objective in our assesment.
