When the namespace and the host-namespace path configurations are changed, the storage system uses the asynchronous event notification for the NVMe-oF communication protocol to issue a notification. The notification is issued to the host connecting to the NVM subsystem whose configuration is to be changed.
If the host supports the asynchronous event notifications for the NVMe-oF communication protocol, the new namespace can be recognized without a host reboot. Verify that the host recognizes a device in the namespace after adding the namespace and the host-namespace path. For the procedure to verify the added namespace, see the manual provided for each operating system.
If a host-namespace path is deleted, the command from the host for which the path is set to the namespace is rejected. Verify that all connections from the host to the namespace are disconnected.
