To add the three IOA structure entries, three structure slots must be available in the CFRM policy couple data set. To determine the availability of the structure slots, check the ITEM NAME(STR) NUMBER(xx) parameter, which is used to initialize the CFRM couple data set. This parameter defines the total number of structure slots you can include in your CFRM policy.

To check this structure slot parameter, review the control cards you submitted when you ran the format utility for CFRM couple data sets. If those control cards are unavailable, run the report utility to display the contents of the CFRM couple data set. For the names of these utilities, see the IBM document z/OS V1Rx MVS Setting up a Sysplex. Compare the structure slot parameter number to the number of structures you included in the CFRM couple data set. If you have three additional structure slots, you can continue with Checking Coupling Facility space usage.

If you have fewer than three structure slots, use one of the following methods to create additional slots in the policy for IOA structures:

• Delete the required number of unused, existing structure entries from the policy.
• Using the format utility for CFRM couple data sets, create a new couple data set with a larger structure slot parameter, and activate it.
