Label data comparison with DFSMSrmm data

Table 1 shows the comparison between label data and DFSMSrmm data.

Table 1. Label data comparison with DFSMSrmm data

Note: Values for volume sequence number in HDR1 and DFSMSrmm data may be different. Volume sequence number in HDR1 indicates the order of the volume within the multivolume aggregate (set of volume serial numbers for one multivolume dataset), whereas the volume sequence number in DFSMSrmm indicates the sequence number of a volume in a multivolume set.
