CMMVC8463E The port cannot be removed because the host is mapped to at least one volume which have received I/O within the defined volume protection period and the port is the last port associated with the host.

Explanation

If volume protection is enabled and the host port being deleted is the last port for a host mapped to any volume which has received I/O within the defined volume protection time period, the command will fail.

The same behavior applies for rmhost: the policing will allow the last host port to be removed if the host is already offline and there is another host mapped to the volume.

User response

Ensure no host I/O is being sent to the volumes and ensure you have waited for the defined volume protection time period or disable volume protection.
