aggregate offset on volume

[gshiman]

Does anyone know if there is a way to determine offset of an aggregate on volume, e.g. tape volume? SHOW BFO and SHOW INVO queries return offset of objects relative to beginning of an aggregate, but I couldn't find TSM query to get an offset of an aggregate relative to beginning of the volume.

I assume this is stored somewhere in the catalog, since TSM restore must know offset of an aggregate in order to restore individual objects in that aggregate.

Thanks in advance,
George
