Explanation

The model of common storage utilization for this LPAR has predicted that usage of common storage will exceed the threshold set by the user before the current model interval ends at nextmodeltime. The prediction was modeled at lastsuccmodeltime. The threshold used in the calculations is controlled by the user of predictive failure analysis by modifying the THRESHOLD parameter for this check. See the IBM® Health Checker for z/OS® report for the PFA_COMMON_STORAGE_USAGE check to determine which storage locations caused the exception and which jobs may have contributed to the problem.

System action

The WTOTYPE of the check has been changed to NONE so that subsequent runs of this check will not produce an operator message until new data is available. The check will collect data and model new predictions at the next collection interval. After modeling is successful, if the current setting of WTOTYPE is still NONE, the previous setting will be restored so that the check will issue future exceptions based on that setting.

Operator response

A list of candidates for the cause of the problem has been produced which may contain the job or address space which is causing common storage to be exhausted. Review the list of candidates and follow your standard diagnostic procedures to determine what actions are needed to prevent common storage exhaustion from occurring. If storage has expanded from SQA to CSA and the exception is in CSA storage, both CSA and SQA have been marked as causing the exception. If storage has expanded from ESQA to ECSA and the exception is in ECSA storage, both ECSA and ESQA have been marked as causing the exception. A list of top users of common storage can be found in the reports for the VSM_CSA_THRESHOLD check and the VSM_SQA_THRESHOLD check.
