DCOLLECT Outputvpercentage value will indicate the percentage of the migrateddata sets that are eligible to be migrated but are not migratedbecause of the thresholds settings.The automatic secondary space management, includingmigration cleanup and level 1 to level 2 migration, runs tocompletion. In this case, all data sets eligible for migration aremigrated and hence the percentage of the migrated data sets thatare eligible to be migrated, but are not migrated, will be zero.UCNINTVUCINTVMThe percentage value is not valid if one of the following conditionsoccurs:vvAutomatic secondary space management does not run for theday because it is not scheduled to run, N-day in cycle. In thiscase, the percentage of the migrated data sets that are eligible tobe migrated, but are not migrated, will be zero.Automatic secondary space management runs but does notcomplete because:– DFSMShsm is shut down– DFSMShsm is in emergency mode– automatic migration is held– a target migration volume is not available– the maximum number of unsatisfactory or unexpected CDSrecords is encountered– Secondary space management ending time is reached andDFSMShsm is not asked to collect the data by patching theMGCFDCOL field to X’FF’. In this case, the percentage of themigrated data sets that are eligible to be migrated, but are notmigrated, will have partial results depending on where theSSM stopped.Contains the number of times interval migration has processed thisvolume on this day. This field does not apply to migration level 1volumes.Contains the number of times interval migration has run andsuccessfully reached the desired target occupancy. This field doesnot apply to migration level 1 volumes.Tape Capacity Planning Record FieldThis is the section for tape capacity planning information. If tape capacity planningrecords are requested, one record is created for each of the following types ofDFSMShsm tapes:v Migration level 2 tapesv Incremental backup tapesv Full volume dump tapes.Both the MCDS and BCDS are needed to create these records. If backup availabilityis not enabled in the installation, the BCDS DD statement in the job must bespecified with a DD DUMMY value.Name DescriptionUTSTYPE Identifies the type of DFSMShsm tapes summarized in this record(backup, dump, or migration level 2).UTFULL Contains the number of tapes that are marked full.506 z/OS V1R6.0 DFSMS Access Method Services for Catalogs
