Where does CA TLMS obtain the volume error stats?


CA TLMS acquires the volume error stats from the IBM SMF 21 records. The following will cross reference the SMF 21 record with CA TLMS volume record.


  • TLMS TEMP READ ERROR  = IBM SMF21TR -  Number of temporary read errors                   


  • TLMS TEMP WRITE ERROR  = IBM SMF21TW  - Number of temporary write errors 


  • TLMS PERM READ ERROR = IBM SMF21PR -Number of permanent read errors. 


  • TLMS PERM WRITE ERROR = IBM SMF21PW - Number of permanent write errors.


  • TLMS ERASE GRAPS  = IBM SMF21ERG - Number of erase gaps.


  • TLMS READ BACKWARD = IBM SMF21TRB - Temporary read backward errors.


  •  TLMS TEMP READ FORWARD = IBM SMF21TRF -Temporary read forward errors.
Additional Information:

You can report on these stats via the CA TLMS Earl report TLERPT05. This report is located at hlq.CTAPEARL(TLERPT05).
