Not without thread-sharing, which AIX HACMP does not support, and a multi-threaded rsync.  Rsync version 3 can thread, but AIX HACMP cannot share execution between nodes, as it was designed to sync state, not split execution.  A way to accomplish something similar to your objective would be to split the list of files you want to rsync, then push each half of the job to one of the nodes.  The downside with that is if one of the nodes should fail during the rsync, then the entire operation may be left in an inconsistent state, so I doubt that's what you're looking for.

Parallel restore is a functionality of (for example) TSM in cooperation with a GPFS filesystem cluster (which might well be a HACMP cluster), but not of rsync and HACMP, as twichert points out.
