Preference list
The coupling facilities where the structure can be rebuilt in order of
preference. To add a coupling facility to the preference list, highlight
the entry on the left and click Add. To remove a coupling facility from
the preference list, highlight the entry in the list on the right and click
Remove. When the system allocates the structure, it chooses the coupling
facility based on the order of preference. If you specify No for Enforce
order of preference list, the system might reorder the preference list
and choose a coupling facility that meets the following criteria (listed
from most important to least important):
-
Has connectivity to the system trying to allocate the structure
-
Has a coupling facility operational level (CFLEVEL) equal
to or greater than the requested CFLEVEL
-
Is a failure-independent coupling facility in relation to
the coupling facility containing the old structure in user-managed duplexing
rebuild processing. The system will give preference to failure-independent
coupling facilities when allocating the new structure during
user-managed duplexing.
-
Has space available that is greater than or equal to the requested
structure size
-
Meets the volatility requirement requested by the connector
-
Meets the failure-independence requirement requested by the
connector
-
Does not contain a structure in this structure's exclusion
list.
