Hmmm, from what I recall...
* A given file cannot span aggregates.
* A file larger than the aggregate limit (which is typically the transaction
max limit) won't be aggregated.
* TSM (and ADSM) provides the concept of "unlimited" storage. TSM can handle
any size file and is limited only by the underlying filesystem and available
storage space. (you can't store 100TB if you only have 1TB of space)
* Aggregates (a collection of files) and un-aggregated files can (and do!) span
volumes if there isn't enough space on the initial volume.
So, your example below isn't quite correct. A 15GB file (which is larger than
the aggregate limit) would NOT be aggregated. And, that file would use one and
a half 10GB volumes (for the drive in the example).
TSM will not store "fragments" of a file. If the file you're trying to store
is larger than any pool's available space, the operation will fail.
