Secondary VRS Jobname: Job name mask of the secondary VRS for this data set.

Secondary VRS Mask: Mask that matches the VRS management value of SMS management class.

Secondary VRS Subchain Name: Name of the subchain VRS.

Security Class: Security Class name.

Storage Class: DFSMS Storage Class for the data set.
