I think if you read the TSM Administrator's Guide they have different deviceclasses for the drives for the very reason to prevent TSM trying to append to the end of a 3590B tape. What happens is it will use new tapes for scratches but only read the old ones until they go through reclamation and get recycled. At least that is the way that I read it. So setting up the device classes correctly is important.

The first time a 128 track tape is written to by an E1A it is converted to 256 track format (Hmmm what about appends - I suppose it's intelligent) So you *should* be able to convert all drives at once. My conversion happened before I started here, but as tapes expired they were reclaimed and I had problems with insufficient mountpoints (when there were drives idle) and the TSM server hanging. I raised a problem on this but then suddenly all of the old data expired and I no longer had the means to recreate the error. I'm on AIX 4.3.3 and TSM server 4.1.3. So, be careful, should and can might be different.

Is there any other documentation/procedure I can review. I've been asked to convert. Is it a simple process? should I upgrade all drives at onetime? Do I need a second device class? How could I use the old vols on the new drives?

Native capacity should be 10 GB. They do not support the K tapes. Upgrade to 3590E1A for that support and 256 track tapes. Orville L.

"q vol" reports: Estimate Capacity is about 18GB, Status is FULL, Pct Util is about 95-100% and Pct. Reclaimable Space is about 0-5% (There is no tape with more then 18GB). Compression is done on the Drive side. FORMAT = DRIVE is defined on the Devclass. I would expect that the Estimate Capacity should indicate the actual capacity on the tapes (after compression), regardless of what is defined on the Devclass. Is this a real problem or only a report problem? Any idea? Nathan Himmel Semech Software Marketing LTD.
