I am not sure whether you want to use SRDF/TC within a cluster or
between clusters. With SC Geo this should be straight forward also not
tested yet.
With campus cluster, once this agent is available it should be a matter
of testing.

It is my understanding that a secondary I/O domain is already supported.
At least one of the configuration diagrams in the suncluster wiki shows
a config with 2 I/O domains and volume mirroring and IPMP setup between
these IO domains.
