TS3500 libraries are often equipped with a sort of virtualization facility, called ALMS, that allows setting up one or more logical libraries within a physical TS3500. If you end up with this facility installed, you will have to deal with a two-tier checkin process: getting volumes into the right logical library, and then getting them recognized by TSM. I think you can configure the library so that it associates volume number ranges with specific logical libraries and automatically puts newly inserted volumes into the appropriate logical libraries. If you use the tape drive encryption capabilities, you will need to use the TS3500 management interface to enable encryption. My experience with TS3500s and encryption involves application managed encryption. I don't know whether there are any additional complications if you use library managed encryption or system managed encryption. Thomas Denier Thomas Jefferson University Hospital
