- If the failure involves a DFSMSdfp component and ISMF does not
seem to be involved, go to Type-of-failure keyword.
- If the failure seems related to ISMF, use Figure 1 to
identify the failing function, and continue.
- Use this table together with the associated entry in the ISPF
log to isolate the failure source. ISMF's use of the ISPF log.
Locate the SERVICE item in the failure-related log entry. Each SERVICE
has its own description for failure-related return codes and reason
codes.
- If the job control language (JCL) that ISMF created for a DFSMSdss or
ICKDSF function is correct, or if DFSMShsm is in control, and the failure
occurs in either DFSMSdss or DFSMShsm, use z/OS DFSMSdss Storage Administration or z/OS DFSMShsm Diagnosis,
as appropriate. If the failure occurs in DFSMSrmm, use the z/OS DFSMSrmm Diagnosis Guide.
- If the failure involves a reason code associated with one of the
DASD common services, use the DASD common services-specific sections
of the keyword build procedures and see DASD common services diagnostic aids to
gather additional failure-related information.
- To begin developing the keyword string, go to Type-of-failure keyword.
