Maybe you would like to check out those Sources, the FreeBSD Developer
use the CARP and GEOM Framework for HAST.

http://wiki.freebsd.org/HAST
http://svn.freebsd.org/viewvc/base/head/share/examples/hast/?pathrev=204076

I assume it's not possible at the moment, cause OHAC/IHAC/Sun Cluster is
a Kernel Based Cluster, if there are changes in the Kernel and no Change
in the Cluster Source, massive Changes in the Kernel will break the Cluster.

OHAC was not maintained and  the Development stopped, i assume the IHAC
Guys have a lot of Bug fixing to do, before it really gets usable.

If you really need the Cluster  stick to Opensolaris 2009.6 Build 111b
