AIX - HACMP - replication

Hi,

A couple years ago I inherited a few systems that use Timefinder and SRDF.  I have just enough timefinder, srdf and EMC knowledge to support the nightly batch replication jobs that run.

A new environment is being proposed that has me confused.  If I have a source1  system that replicates to a target1 each evening and source1 is an active node in an hacmp active/passive type setup, can this be setup to still run replication in a "failed over" condition?

For example, assume source1 requires some sort of hardware maint so we fail the resource group/IP to the passive node, source2.  Is it possible to set this up so that the nightly replication runs from source2 to target1 without manual intervention?

I seem to rember some things in /usr/emc that would need to be the same across the hacmp cluster.  Is it as simple as putting the cli/db/keys on shared disk?  Is there doc for this?

Thanks!
