Example with CF in MAINTMODE

In the following example, a coupling facility that has already been activated is reintegrated into the sysplex in two steps:

The coupling facility is taken out of maintenance mode.
Note: It is no longer necessary to turn the sender paths offline when the coupling facility is in maintenance mode, regardless of whether or not all systems in the sysplex run z/OS® 1.9 or later.
All structures that have the target coupling facility as the first coupling facility in their preference list are allocated on the target coupling facility.

If you issue INGCF with the ENABLE option, you can specify the coupling facility to be reintegrated, for example, by entering INGCF ENABLE CF02. If you do not specify a coupling facility name, INGCF shows a selection panel with all coupling facilities that are defined in the sysplex.

The selected coupling facility has already been activated manually, therefore its status, as shown on the right of the panel header in Figure 1, is MAINTMODE. The authorization type of the operator (ALL) is also displayed on the right of the panel header. The structure list contains 10 entries with the condition Structure is currently allocated in CF01. These are the structures that are currently allocated in CF01, but have CF02 in the first position in their preference list. The only action that is activated is MAINTOFF with F5.

If you press F5 a confirmation panel is displayed.

After pressing F10 on the confirmation panel, the command dialog shows the new status and a new function key.

The status has changed to NORMAL, and F10 is enabled for populating the coupling facility. This implies that the target coupling facility is defined in the active CFRM policy.

Pressing F10 and confirming the action populates the coupling facility.
