Short answer: Use the type 74's, as RMF does.
Our RMF Mon III CF Report shows:
CF Policy: NORMAL Activated at: 05/06/10 18.15.31
----- Coupling Facility ------ ------ Processor -------
Name Type Model Lvl Dyn Util% Def Shr Wgt Effect
CF01 2097 E40 16 OFF 2.8 1 1 950 1.0
CF02 2097 E40 16 OFF 1.1 1 0 1.0
This data comes from the type 74's, as does SYSRPTS(CF), so I don't
understand your statement:
"I am seeing the TYPE70 records showing the ICF as 100% busy (z/OS 1.9)
and the RMF Reports Coupling Facility reports showing the same thing."
>From RMF on SYSRPTS:
CF | NOCF
Specifies the Coupling Facility Activity report. To obtain an entire
Coupling
Facility Activity report, ensure that you supply the Postprocessor with a
complete set of SMF 74 subtype 4 records from all systems in the sysplex
