I think the answer to your question is "NO". The PREFIX gets written into the INTERNAL tape label, in the data set name field, not the volume field, doesn't have anything to do with barcodes.
PREFIX is useful if you have a mainframe TSM server, because that name can be useful in identifying your TSM tapes to the mainframe tape management system. (On non-mainframe TSM servers, TSM does its own tape volume management. On the mainframe, you usually have TSM interface with the existing mainframe tape management system.)

Hi there, We have the venerable IBM 3584, and I created a devclass "dbtape" with a prefix of "TDB". I then printed a set of barcodes TDB001L2 ... TDB015L2. Checked in the tapes as scratch, labels=b, etc. q libvol shows them. When I went to backup db devc=dbtape, it picked a scratch tape with a different prefix. Does the PREFIX option actually do anything on an LTO library? What I want is to use the PREFIX attribute to control which tapes can be used for a database backup, rather than maintaining a file of appropriate volume labels. TIA, --Jim
