I think you can't really restore that VSAM data set unless you know how it was defined initially. Downside of physical dumps. Creation/deletion/modifying characteristics of a VSAM data set cuts an SMF x'60' record, see http://ibm.co/SMF60 for details. So if you can find a x'60' record of the original data set (either when it was created or deleted), you'll get the full VVR (VSAM volume record) of the VVDS, which *must* contain all the stuff you'd need (key lengths etc.). However, it's not documented. Maybe if you ask IBM nicely they give you some hints about the layout of the SMF60CRC field... otherwise, you should be able to reverse-engineer where key-/record lengths etc. are located (define/delete a couple of clusters, change key-/record lengths etc. and compare the differences in the resulting x'60' records).
