In these examples, it is assumed that you run vital records selection processing on a regular basis. Define vital record specifications for volumes that can be moved to free up space that is based on installation policies and information available from DFSMSrmm. The vital record specifications might differ from other vital record specifications you define in that they are in effect for a short period of time or only manage a subset of volumes or data sets. The vital record specifications must use more specific data set name filters to override existing vital record specifications. They should include information about how long data resides in a system-managed library and when it can be removed and returned. After you define the vital record specifications they take effect at the next run of vital records selection processing and can be deleted at any time so that the previous policies are in effect.
