This report summarizes the coupling facility storage-class
memory (SCM) utilization for CHECK(XCF_CF_SCM_UTILIZATION).
CFNAME:
The coupling facility name.
An asterisk
(*) before a CF Name indicates that the SCM utilization for the coupling
facility
exceeds a defined utilization threshold for
the check.
SCM Utilization:
The current storage-class memory (SCM) utilization for the coupling
facility.
SCM Utilization is determined
by the sum of the SCM frames currently in use across all
structures in the facility. "N/A" indicates that SCM is not available
to the coupling facility.
Total SCM Space:
Total amount of storage-class memory available to a coupling facility
that may be used as
structure extensions. "N/A" indicates
that SCM is not available to the coupling
facility.
Severity:
The exception severity level for an individual coupling facility.
The severity level is based on the
defined utilization
thresholds for the check. The severity can be NONE, LOW, MED and HIGH.
The overall check exception severity will be the highest severity
found by the check for an
individual coupling facility.

This
is a report for CHECK(IBMXCF,XCF_CF_SCM_UTILIZATION) that displays
the storage-class memory (SCM) utilization percentage for coupling
facilities managed by the local system and whether the current SCM
usage exceeds a defined utilization threshold for the check.In the
report:
- cfname
- The name of the coupling facility processed by the check.
- utilization
- The percentage of SCM for the coupling facility currently being
used. SCM used by the coupling facility is determined by the sum of
the SCM frames currently in use across all structures in the facility.
- totl scm
- The total amount of coupling facility SCM available for use by
structures expressed in units of kilobytes (K), megabytes (M), gigabytes
(G), or terabytes (T).
- severity
- The exception severity level for an individual coupling facility.
The severity level is based on the defined utilization thresholds
for the check. Severity is one of the following:
When an SCM utilization threshold is exceeded for the coupling
facility, the report will include SCM utilization information for
each allocated structure using SCM. In the report:
- strname
- The name of an allocated structure using SCM, and the structure
status. 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.
- PND
- Deallocation is pending for this structure because a structure
dump is associated with this structure. The structure deallocation
remains pending until the structure dump is either forced or written
to a dump data set.
- strcfname
- The name of the coupling facility that the structure is allocated
in.
- str util
- The current percentage of the total amount of storage-class memory
available to the structure currently in use.
- assigned scm
- Total amount of storage-class memory available to a coupling facility
structure that may be used as structure extensions. The total amount
of coupling facility SCM available for use by structures is expressed
in units of kilobytes (K), megabytes (M), gigabytes (G), or terabytes
(T).
