CMMVC8459E The volume cannot be removed because the volume has received I/O within the defined volume protection period.
Explanation
If the last volume copy is being deleted, volume protection
is enabled, and the volume being deleted has received I/O within the
defined volume protection time period, then the command will fail.
This behaviour is not changed by the volume being mapped/unmapped.
Deleting one (of two) volume copies is not affected.
The force flag does not affect this policing behaviour. For example, the force flag does not override the policing.
User response
Ensure no host I/O is being sent to the volume and
ensure you have waited for the defined volume protection time period
or disable volume protection.
