Coupling facility structure minimum counts is summarized by the following report:

Explanation
Where text is:
Entry Entries Element Elements
Structure Name Minimum Allocated Minimum Allocated
--------------------- ---------- ---------- ---------- ----------
strname entmin entalloc elemin elealloc
The report lists structures allocated with the capability to use SCM (storage-class memory), their
structure object minimums, and their count of structure objects allocated in real storage. The
report is generated as part of CHECK(IBMXCF,XCF_CF_STR_SCM_MINCOUNTS).
An asterisk (*) before a structure name in message IXCH0930I indicates a structure that should be
duplexed and has less structure objects than the minimum required to allocate with SCM.
When the check is run in verbose mode, all structures allocated with the capability to use
SCM will be included in the report. In the report:
- strname
- The structure name and status. If no status follows the structure name, then only one
instance of the structure is allocated. The status can be one of the following:
- (OLD)
- A structure rebuild process is in progress and two instances of the structure are
allocated. This is the old instance of the structure. The structure rebuild process
type is either rebuild or duplexing rebuild.
- (NEW)
- A structure rebuild process is in progress and two instances of the structure are
allocated. This is the new instance of the structure. The structure rebuild process
type is either rebuild or duplexing rebuild.
- entmin
- Minimum entry count.
- entalloc
- Maximum entry count
- elemin
- Minimum element count.
- elealloc
- Maximum element count.

Problem determination
Exception message IXCH0265E is present in the message buffer when the check
finds that a coupling facility structure that the policy permits to be duplexed has a number of
structure objects less than the minimum required to allocate with SCM.
