This is a classic situation where the disk pool is undersized relative to
it fills (perhaps helped along by stpool caching overhead) and TSM rules have
data go to the next stgpool in the hierarchy. Transaction sizing and
size anticipations are also factors. The cure is to have a generous disk
pool, unless you can identify other contributing factors in your configuration
(compression, etc.). Disk is cheap, so go for it.
