John, The cpus defined as CF (specialty) engines ONLY run the CF code, so there is no gain to you SYSA/B/C/D lpars.
Are you running a parallel sysplex? Also I think the GP engines are in one pool, and the CF engines in another so your weights aren't giving you the MIPs you think.

Wts are in such a way that MIPS Allocation are 650 for SYSA 50 for SYSB 50 for SYSC 50 for SYSD 100 MIPS for SYCF1 and 36 MIPS for SYCF2 , SYSA is UNCAPPED and SYSB, SYSC and SYSD are CAPPED. Recently we are having issues related to MIPS capacity. I am aware that in case SYSA needs more capacity then it can take from SYSB,SYSC,SYSD if available. However, was wondering whether system will allow to take MIPS from Coupling Facility LPAR's as well or not if available ? These are the structures in use for CF ISGLOCK IXCXCF1 IXCXCF2 Is there any advantage in getting rid of these coupling facility ? Will that give us comfort ofhaving these additional MIPS ?
