So now for the question at hand, how do aggregation and the maxsize parameter interact? Both during B/A and migration/reclamation?
Remco - There's no mystery in this - it's all laid out in the IBM documentation, as previously indicated. During backup, client data is formed into a transaction according to the limits imposed by the TXN* parameters, and if the determined size fits in the primary landing area, it goes there, else further down in the stgpool hierarchy. Migration can happen if the current size of an Aggregate fits in the next lower stgpool. Your desire to service restorals without tape argues for an investment in some kind of disk array, with a Migdelay value such that older data migrates to tape. a weary Richard Sims
