When a cluster is defined with the ERASE option, it means the data component's extents must be overwritten with binary zeros when it is deleted. Occasionally it is necessary to override this option in order to delete the cluster. When CA Disk deletes a cluster, it uses the value with which the cluster was defined (ERASE or NOERASE). If sysparm VSNOERAS is specified with a value of Y and a cluster defined with the ERASE option fails deletion with a specific return code, CA Disk will retry the deletion overriding the ERASE option (effectively making it a NOERASE option). This is equivalent to issuing an IDCAMS DELETE command with the NOERASE parameter specified. Note that even with this sysparm specified, CA Disk will attempt to delete the cluster first with its default value. Only if the sysparm is specified will CA Disk retry the deletion. (The default value for this sysparm is N, which allows the deletion to fail and processing is bypassed for the cluster).
