N-2 Support

Prior to the release of this PTF, PowerHA and clustering only supported a difference of one release. This meant that the nodes within the cluster needed to be within 1 release, and a node within the cluster could only be upgraded one release at a time.

Once this PTF is installed, a 7.1 node can be added to a 5.4 cluster.

A node can also be upgraded from a 5.4 cluster node directly to a 7.1 cluster node as long as this PTF is installed during the upgrade.

The main intent of this PTF is to allow nodes to be upgraded directly from 5.4 to 7.1. PowerHA replication of the IASP still does not allow replication to an earlier release, so for a complete high availability solution, other than during an upgrade of the HA environment, all nodes should remain at the same release level.
