Further develop the storage pool migration mechanism

See this idea on ideas.ibm.com

Develop the storage migration mechanism (both the MIGRATE STG command and automatically initiated equivalents) to either move data at a more granular level than node ownership, or develop it to support multiple processes per whatever level of granularity you support, currently the node level. � Currently a single node can fill up the initial destination for a domain�s copygroup, such as a storage pool of DISK devices, faster than a single MIGRATE STG command can empty it if the output device for MIGRATE STG isn�t particularly fast. Allowing MIGRATE STG to use more than one process for a storage pool doesn�t matter if TSM won�t use more than a single process for a node�s data, even if the data comes from several file systems. Allowing MIGRATE STG to use more than one process per a node would give MIGRATE STG a better chance of staying ahead of an unusually large backup stream from a single client, preventing the eventual overrun of the storage pool in question. The one process per node model may have fit well a decade ago when storage I/O speeds were much faster than IP network speeds, but that model is breaking down in current data center configurations.
