Abstract

LIC-OTHER-UNPRED CHANGE OF PACING DEFAULTS FOR UNMAPPING
FREESPACE TO SVC BASED STORAGE.

Error Description

Internal SMFSUNMAP_WORKER task(s) currently being used when    
IBMi is connected to SVC based external storage to help open    
up actual free space on the external storage LUNs. This worker  
task can be quite aggressive in some environments,              
therefore a code change is going to be a result of this APAR    
which will change the default pacing behavior by this task and  
allow the ability to modify if needed through an Advanced      
Analysis Macro.                                                

Problem Summary

Please see the ERROR DESCRIPTION section.                      

Problem Conclusion

The default pacing behavior will be changed to slow the task    
down.
