Explanation: ML2RECYCLEPERCENT(pct) is an optional parameter specifying the percent-valid criterion DFSMShsm uses to recycle tape migration level 2 volumes, if you do not specify the PERCENTVALID parameter of the RECYCLE command. For pct, substitute a decimal number from 0 to 100. When DFSMShsm invalidates a data set entry for a full volume and the percentage of valid data on the migration level 2 tape volume becomes less than or equal to pct, DFSMShsm writes the informational message, ARC0365I, in the command activity log.
For a discussion of how DFSMShsm calculates percentages based on valid blocks, refer to Consolidating valid data on tape volumes.
SMS relationship: Parameter has the same meaning when applied to SMS-managed or non-SMS-managed DASD volumes or data sets.
SETSYS default: None.
DFSMShsm default: If you do not specify this parameter on any SETSYS command, DFSMShsm will use the value specified with the SETSYS RECYCLEPERCENT parameter.
