Explanation
If volume protection is enabled, and any volume in
the pool being deleted has received I/O within the defined volume
protection time period, then the command will be failed.
This behaviour
is not affected by the force flag (the command would already be failed
if there are any mdisks in the pool being deleted and the force flag
was not used). For example, The force flag does not override the policing.
User Response
Ensure no host I/O is being sent to volumes in the
storage pool and ensure you have waited for the defined volume protection
time period or disable volume protection.
