Rules and Guidelines

You can define a maximum of 127 data sets for the database. You can move data sets providing:

• The original and new volumes are of the same device type
• Each data set contains an equivalent amount of cylinders as the original,
• The new data sets each contain only one contiguous extent

Note: To improve performance, create a small number of large data sets rather than a large number of small data sets.
