Valid parameters for CHECK(IBMXCF,XCF_CF_SCM_UTILIZATION) are:

SCM_NONE(xx%) or abbreviated as SCM_N(xx%)
SCM_LOW (xx%) or abbreviated as SCM_L(xx%)
SCM_MED (xx%) or abbreviated as SCM_M(xx%)
SCM_HIGH(xx%) or abbreviated as SCM_H(xx%)

where xx is a percent value in the range of 1-100. At least one parameter must be provided. Each parameter corresponds to the severity level that will be reported for the check when the usage of storage-class memory by the structures in a coupling facility exceeds the specified percentage of total storage-class memory eligible to be used by the coupling facility structure.

Note: The percent sign (%) is optional.

Explanation

The parameters for CHECK(IBMXCF,XCF_CF_SCM_UTILIZATION) specify the storage-class memory utilization thresholds that the check uses when raising an exception for the check. At least one threshold parameter must be specified and up to four threshold parameters may be specified that correspond with check exception severity levels. The defined parameters are as follows:

In the message text:
SCM_NONE(xx%) | SCM_N(xx%)
Specifies the storage-class memory (SCM) percent utilization threshold to use when raising a check exception with a severity of NONE when the usage of storage-class memory by the structures in a coupling facility exceeds the specified percentage (xx%) of total storage-class memory available to the coupling facility.
SCM_LOW(xx%) | SCM_L(xx%)
Specifies the storage-class memory (SCM) percent utilization threshold to use when raising a check exception with a severity of LOW when the usage of storage-class memory by the structures in a coupling facility exceeds the specified percentage (xx%) of total storage-class memory available to the coupling facility.
SCM_MED(xx%) | SCM_M(xx%)
Specifies the storage-class memory (SCM) percent utilization threshold to use when raising a check exception with a severity of MEDIUM when the usage of storage-class memory by the structures in a coupling facility exceeds the specified percentage (xx%) of total storage-class memory available to the coupling facility.
SCM_HIGH(xx%) | SCM_H(xx%)
Specifies the storage-class memory (SCM) percent utilization threshold to use when raising a check exception with a severity of HIGH when the usage of storage-class memory by the structures in a coupling facility exceeds the specified percentage (xx%) of total storage-class memory available to the coupling facility.
