Information for managed data sets

The Library Utility option I (Figure 1) displays information for data sets that reside on Storage Management Subsystem Volumes (also called managed data sets) when:

DFSMSdfp is installed and available.
Storage Management Subsystem is active.
Directory block information is available.

Figure 1. Data Set Information for Managed Data Sets (ISRUAISE)

This screen dump shows Data Set Information.

Note: A "+" may be displayed beside the Volume serial field if the data set is a multiple volume data set. This is determined from the number of volume entries in the catalog. Depending on the system set-up, a "+" may not be displayed until the additional volumes have been accessed. For example, a data set with a non-zero dynamic volume count in the SMS dataclass will not show multiple volume entries in the catalog until the additional volumes have been accessed. Other vendor products which can dynamically expand the volume list will also not show multiple volume entries in the catalog until the additional volumes have been accessed.

Press Enter to display a list of all allocated volumes as shown in Figure 2.

Figure 2. Volume Information for a Managed Multivolume Data Set (ISRUAMVI)

This screen dump shows the Data Set Information with the Volume Information pop-up. There are more than five allocated volumes.

The major difference between this information and the information that is displayed for data sets on non-managed volumes is the addition of these classes:

Management class
Storage class
