Serval years ago a wrote a document on configuring tape drives in TSM for 
performance/redundancy. We had some problems today and I had to dig out the 
document. I looked through it and made a couple of minor updates. It still 
seems pretty relevant. I have not made updates to the sections on SCSI drives, 
but they are still included. The document includes a detailed example for AIX 
using fibre drives in an IBM 3584.
 
Please email me directly if you would like the document.
