Communications in HACMP happens via RSCT and for a cluster to work the version of the RSCT-packages have to be in sync. Fortunately it is easy to update the RSCT independent of the rest of the OS.

I hope this helps.

Looks good - however, have you also verified this with an update to SystemMirror (aka PowerHA v7?). As I understand it, SystemMirror is not using (only?) RSCT - but is using CAA (Cluster Aware AIX) for communication, topology and heartbeats. -- I do not do much with SystemMirror so I am asking - anyone - just to be sure someone does not get surprised when working with/updating to SystemMirror.
