CMMVC9173E The pool specified is a data reduction pool. Thin provisioned or compressed volume copies created from a data reduction pool must use -autoexpand.
Explanation
When you create a volume copy from a data reduction pool, you must enable the autoexpand capability. The command fails if you try to create a thin-provisioned or compressed volume copy from a data reduction pool and do not specify the -autoexpand parameter.
