Explanation: ALL specifies that all cartridge-type single-file tape volumes that are marked as full in the OCDS TTOC record and do not have an alternate volume are to be copied. If the environment is PARTIALTAPE(MARKFULL) when this command is issued, all partially full migration level 2 tapes will be marked full.
Tape library relationship: A UNITNAME can be used for filtering in the ACS routines. If you specify the unit type for this command, it will be sent to the ACS routines in SMS for the TAPECOPY function.
When ALL is specified, DFSMShsm uses scratch tapes for the output or target volumes.
Defaults: None.
