IXCH0925I
This report summarizes the coupling facility storage-class memory (SCM) utilization for CHECK(XCF_CF_STR_SCM_UTILIZATION).

When the check is run in verbose mode, IXCH0925I is issued to list all allocated coupling facility structures with assigned storage-class memory (SCM). The structures that are exceeding a defined threshold utilization percentage for SCM are listed first followed by structures that have not exceeded any threshold utilization percentage.

Structure Name:
   The structure name.
CFNAME:
   The coupling facility name where the structure resides.
SCM Utilization:
   The current SCM utilization for the coupling facility structure. SCM Utilization is the percentage
   of SCM frames eligible for use by the structure that are currently being used by the coupling
   facility to hold migrated structure data.
Eligible To Be Assigned SCM:
   Total amount of SCM available to a coupling facility structure that may be used as structure
   extensions.
Severity:
   The exception severity level for an individual coupling facility structure.
   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 structure.

This is a report for CHECK(IBMXCF,XCF_CF_STR_SCM_UTILIZATION) that displays the SCM utilization percentage for coupling facility structures configured to use storage-class memory.

When the check is run in verbose mode, IXCH0925I lists all allocated coupling facility structures with assigned SCM. The structures that are exceeding a defined threshold utilization percentage for SCM are listed first followed by structures that have not exceeded any threshold utilization percentage.

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.
cfname
The name of the coupling facility in which the structure is allocated.
used
The Start of changeEnd of change percentage of the total amount of storage-class memory available to the structure that is currently in use.
eligible scm
Total amount of storage-class memory available to the 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).
severity
The exception severity level for an individual coupling facility structure. The severity level is based on the defined utilization thresholds for the check. The overall check exception severity will be the highest severity found by the check for an individual coupling facility structure. Severity is one of the following:
  • NONE
  • LOW
  • MED
  • HIGH
