Operating Systems AIX Thoughts on HACMP: Automatic start of cluster services Post 302843525 by MichaelFelt on Tuesday 13th of August 2013 03:55:10 PM

Since HACMP 5.X the cluster manager gets started automatically - that is why it is in the inittab.

There are three kinds of resource groups and each have their own startup (node just coming up) and recovery policy.

So, to be to the point: HACMP v4 and earlier did not have HACMP in inittab as best practice - because the cluster manager was not always active. Starting with HACMP v5 the cluster manager is always active, so the daemons (not the resource groups) are always (meant to be) activated when the node/server starts.

Hope this helps.
