In this example, a VVDS is explicitly defined. The cluster is named using the restricted VVDS name format 'SYS1.VVDS.Vvolser'.

This DEFINE CLUSTER command defines an entry-sequenced cluster that is used as a VVDS. The parameters are:

• NAME specifies the name of a VVDS, 'SYS1.VVDS.Vvolser', SYS1.VVDS.VVSER03.
• VOLUMES specifies that the cluster is to reside on volume VSER03. Only one volume serial can be specified.
• NONINDEXED specifies that the cluster is entry-sequenced.
• CYLINDERS specifies that the cluster's space allocation is 1 cylinder. When the cluster is extended, it is extended in increments of 1 cylinder.
