When inventory management fails

If you are experiencing problems during inventory management, you can perform one of these tasks:

Determine if the data sets used by inventory management are Resource Access Control Facility (RACF®, a component of the Security Server for z/OS) protected. If so, ensure that the RACF user ID that runs inventory management has the authority to write to the data sets.
Preallocate data sets as described in the z/OS DFSMSrmm Implementation and Customization Guide before you use the inventory management functions. For example, if you want to obtain an extract report and retain messages issued during inventory management, you must preallocate a REPTEXT file and a MESSAGE file, used in the sample JCL for EDGHSKP in Figure 1. EDGJHKPA Sample JCL for Allocating the Data Sets Required for Inventory Management is a DFSMSrmm sample provided in SAMPLIB and can be used as an example to preallocate a REPTEXT file and a MESSAGE file.
Figure 1. Sample JCL for EDGHSKP
```
//HSKP      EXEC PGM=EDGHSKP,PARM='RPTEXT'
//SYSPRINT  DD   SYSOUT=*
//MESSAGE   DD   DSN=DFSMSRMM.MESSAGE.DATASET,DISP=SHR
//REPTEXT   DD   DSN=DFSMSRMM.EXTRACT.DATASET,DISP=SHR
```
.
Check the system log for error messages when the job message log or DFSMSrmm MESSAGE file does not contain enough information to identify the error. Because DFSMSrmm inventory management runs in the DFSMSrmm subsystem address space, error messages might have been written to the system log.
Check if you are using the OPTION command operands: VRSDROP, VRSMIN, VRSRETAIN, or EXPDTDROP with the action of FAIL. If so, inventory management processing stops, if the appropriate limit was triggered. The EDG2310I message and other messages in the DFSMSrmm MESSAGE file will show details in this case.
