Hello I use raw and TSM mirroring because I was told that idf I had a problem and used OS mirroring TSM did not support that. If I wanted TSM support I would need to do TSM mirroring. So make sure! Mike

That's because after a weekend of dsmfmt-ing, I'm declaring the thing BROKEN worse than before. I take back those nice things I said last Friday. I'm not using raw LVs because I want to use OS mirroring on my disk storage pools. Also the ITSM Administrator's Guide goes to some length to convince you not to use Raw LVs, and I tend to believe the basic manual for any product when they come out and say something and are that sure of it. What bewilders me now about dsmfmt is two questions: 1) Why does the error message tell me how big to specify for some disks and not for others? The Logical Volumes are identical except for size. On a 72gb disk, if I overestimate, it says how big to use. On a 36gb disk, it's like before, where I get to guess, and then wait several hours to find out if I guessed right or not. 2) Why is it's calculated number so low? After dsmfmt was done, the Unix df command showed that filesystem only 94% full, with nearly 5gb showing free on df on a 72gb disk. That's a lot of waste! I'm not so sure this new feature is such a great idea if it is going to forbid me from getting my disk as full as possible. By the old method of trial and error and waiting for hours, I could usually get it well over 99% full, according to the Unix df command. Now I really want that option you suggest - use it all (I mean, really use it all) and tell me how much space I've got when I'm done. The current state of affairs in V5.1 is worse than just wasting a lot of my time; now it is wasting my disk space as well, and it is behaving inconsistently. A consistently-behaving, easy to use to allocate all of something, version of dsmfmt is VITAL to disaster recovery capabilities!
