So the key for this message is
REQUESTED SPACE QUANTITY = nnnn {KB|MB}
What was in this message.
Typically I find this message occurs when the volumes being selected do not
have sufficient space for allocation. Also because the space parms are not
tuned to handle daily usage vs. high water mark storage allocation.
What is the SPACE= parameters being use?
How many extents is the dataset going to
What does the pool look like? Are there lots of volumes will less than
adequate storage on them?
SMS is not always going to pick the volumes we think it should. The algorithm
can go after volumes less than optimal.
There is a Share presentation from 2011 that may help
DFSMS Basics: How SMS Volume Selection Works
Page 11 in this presentation shows a great graphic of how a volume is selected.
Hope this helps
