For your new VTS/3584 configuration, be aware, that you need a third box beside VTS and 3584 called 3953, which hosts the FICON/ESCON interfaces, the library manager and the controller(s) for the 3592 tape drives.
For your disaster recovery, it is important, that the vts at Sungard is standalone for you. Otherwise you cannot simply put the tapes into the vts and start recreation. Another thing to be aware of is the management of the logical volumes on vts. Inside the vts there is a tsm running which knows where the logical tape volumes are backed up on the stacked volumes. This tsm database is backed up at the end of each stacked volume just before the stacked volume is filled completely. Therefore in a disaster recovery when your vts is gone, you will loose all logical volumes since last backup of the tsm database. In case of a 3592 tape with 300GB unpacked capacity, it may last some time until a tape is filled and the tsm database is backed up again, and the vts has several stacked volume tapes tapes open in parallel. If you want to avoid this risk, you should consider to use a peer-to-peer vts solution. Please don't misunderstand me. I think the vts is a good solution for using the whole tape capacity of today's large tapes, but disaster recovery is another challenge than on the traditional libraries. You don't have a real tape with a DSS-dump, which you can mount. You have only the stacked volumes which are readable only from VTS.
