Also, backups running during the migration time can prevent the pool from reaching 0. We use 1 to get around that problem.

When you change the LOWMIG value TSM waits till it has moved *all* files of the node it is currently working on. So this might take some time if you have nodes with many, many files.

The below percentages don't seem right since I have the following settings. Anyone else see this as odd or am I missing something? If so what could be causing this?
