Determining which tape migration level 2 volumes are available for output

To find out which tape ML2 volumes are available for migration processing, follow this procedure:

  1. Issue a QUERY MIGRATIONLEVEL2 command.
  2. Look at the volume serial numbers of the ML2 volumes. The ARC0227I message shows the volsers of the tapes currently associated with the respective data set, volume, and secondary space management tasks. These are the tapes DFSMShsm attempts to allocate when the tasks start. If you want to know what other ML2 tapes exist and might be used in place of these, issue LIST TTOC SELECT(NOTASSOCIATED).
  3. Issue one of the following commands to determine which tape ML2 volumes are empty and available for subsequent volume selection (if you specified SELECTVOLUME(SPECIFIC) on the SETSYS command): 
    LIST MIGRATIONLEVEL2(TAPE) SELECT(EMPTY)

LIST TTOC SELECT(ML2 EMPTY)
