Simply stated, 'PowerHA SystemMirror for AIX' is the new name of the SW product formerly known as 'HACMP'.
The product documentation is available here:

Up till Version 5.4, or strictly speaking 5.4.1.x HACMP (High Availability Cluster Multiprocessor) is known as HACMP.

Version 5.5 was Re-branded as IBM PowerHA (effectively the same as HACMP, of course with more features etc with each subsequent releases).
Next Major Version v 6.1 was further Re-branded as IBM PowerHA SystemMirror
The latest version i.e 7.1 is hence known as PowerHA SystemMirror 7.1

But all of them are essentially IBM HACMP Cluster/High Availability solution for Aix and Linux on Power and System-i.

Hope this clarifies.
