I just experienced this same problem this weekend when re-defining some
disk storage pools. I was using the DEFINE VOLUME command instead of the
DSMFMT utility. The command would fail but there would still be 408000
512-byte blocks left in the filesystem. The number of blocks left in the
filesystem seemed to be unrelated to the size of the volume I was trying to
define as it failed at the same place on different size volumes. I would
also be interested in why TSM doesn't use every available block...

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

Subject: dsmfmt question
Hi *SM-ers!
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!!!
Kindest regards,
Eric van Loon
