Mary--What you're seeing is fragmentation. TDISK is allocated in one whole
piece to a user. Think of PC disk allocation that you see when you run a
defrag. If you have 1 allocated cylinder out in the middle of an otherwise
empty 100 cylinder TDISK space, you cannot allocate a 99 cyl TDISK. You
would get that by the first user getting 50 cylinders and the 2nd user
getting 1 cylinder. When the first user detaches the 50 cyl. disk, the 2nd
user still has the 1 cyl in the middle. You are left with 99 cylnders in
total free but you can only allocate a max of 50 cylinders and 49 cylinders.

I have 500 cyl. of tdisk defined on one pack and 50 cyl. of tdisk defined
on another. One user used the 50 cyl. on the second pack and about 24
users have used 215 cyl.(43%used) on the first pack. Why is it that I can
only allocate a 130 cyl. maximum tdisk on the first pack but can then go
ahead and allocate a 110 cyl. tdisk, instead of being able to allocate
*one* 240 cyl. tdisk?
Thanks for any help.
