CMMVC6342E: The volume copy was not shrunk because its real size cannot be less than its used size.


You are attempting to reduce the real size that is allocated to a thin-provisioned volume copy, but the command cannot be initiated because it would make the real size less than the size that is currently used.

User Response

Determine the used size of the volume copy, and resubmit the command using a -rsize parameter value that is greater than or equal to the used size.
