This question is nominally directed to Richard Sims because it cites his Quickfacts. But, other knowledgeable people are welcome and encouraged to respond.
In the '3584' entry in "ADSM/TSM Quickfacts" it is said that, "The 3584 is a "SCSI library": the host has to direct its actions. If you're accustomed to the 3494 and its automated actions, don't expect anything like that in the 3584. As one customer said: The 3584 is pretty much an automatic tape mounter with bulk storage and no real 'smarts'. In the 'SCSI Library' entry it is said that, "The TSM server must physically manage its actions, and must keep track of volume locations. ...the work they don't do they shift to the host, and so TSM is burdened with a lot of intricate SCSI element details and control issues." Do these entries describe current 3584 automation features, especially vis-a-vis TSM? If they do, how will TSM server performance and administration change for the worse if we migrate from 3494 technology to a 3584? With many thanks, Keith Arbogast Indiana University
