The cluster name line shows the name, the cluster type, the primary volume serial, the total tracks allocated, and the percentage of space used. This line is always displayed first and cannot be suppressed. If the cluster resides on multiple volumes, the primary volume for the data component will be displayed under the VOLUME heading, followed by a "+" sign (the remaining volumes on which the cluster resides can be found by looking at the extent detail lines). In addition, the total number of control area and control interval splits (data + index) will be shown if splits have occurred. If more than the minimum number of extents are allocated, the number of extents are also shown; that is, more than one for an ESDS or RRDS and more than two for a KSDS.
Note: KSDS clusters defined using the key-range attribute, all VSAM catalogs have at least three extents, and hence the number of extents will be shown.
A cluster data report in which all other detail lines have been suppressed provides a concise cluster summary report.
