If you do not manually define all information about a volume to DFSMSrmm, DFSMSrmm automatically records the remaining information when a data set on the volume is opened or closed. Here are the operands you can change if you are authorized to use the CHANGEVOLUME subcommand FORCE operand:

• ASDATE
• ASTIME
• COMPACTION
• DENSITY
• DSNAME
• JOBNAME
• LABEL
• MEDIANAME
• MEDIATYPE
• MEDINF
• NEWVOLUME
• ORIGINALEXPDT
• READDATE
• RECORDINGFORMAT
• WRITEDATE

To use the FORCE operand, you must have CONTROL access to STGADMIN.EDG.MASTER security resource and UPDATE access to STGADMIN.EDG.FORCE security resource.
