Problem summary

  • ****************************************************************
    * USERS AFFECTED: DirMaint users with extent efficient         *
    *                 thin provisioned volumes.                    *

    * PROBLEM DESCRIPTION:                                         *
    ****************************************************************
    * RECOMMENDATION: APPLY PTF                                    *
    ****************************************************************
    With the PTFs for APARs VM66098 and VM66108 applied, DirMaint
    PURGE processing of extent space efficient (ESE) volumes is
    enhanced. If an ESE volume is detected during DirMaint PURGE
    processing, DirMaint will now issue the new CP RELSPACE command
    to clear the volume prior to issuing the CPFMTXA command. The CP
    RELSPACE command for the ESE volume provides quicker formatting
    and release of the extents. If and error occurs, DirMaint will
    attempt to clear the volume using the CPFMTXA command.
    

Problem conclusion

Temporary fix

Comments

  • Extent space efficient (ESE) volumes are now cleared during
    DirMaint PURGE CLEAN processing using the new CP RELSPACE
    command.
