Hi Eric, I re-read "TSM implementation guide" Redbook a couple of minutes ago, and they don't speek about any overhead space for a data volume, what they specify is that if you want to format a db volume, then the allocated file size is always a multiple of 4 MB plus an additional 1 MB for overhead. Something else comes to my mind : when preparing your VG, did'nt you forgot the "large file enable" parameter ? Hope this helped, but probably somebody has a better knowledge than I have .... Cheers. Arnaud

I will replace my 9 Gb. SSA disks in the very near future. The new disks (36 Gb. 10.000 rpm) will have to be added to the diskpool one by one. I remember from the last time that it was quite difficult to allocate a disk file which fills the disk completely. If you have, for instance, a 9 Gb. disk, you cannot create a 9 Gb. file by issuing a DSMFMT -G -DATA filename 9. This results in an error indicating the there isn't enough space available. Apparently the dsmfmt utility needs a little bit overhead space. Does anybody know how to calculate the maximum space one can specify to fill the disk to it's maximum? Thanks in advance for any reply!!!
