You can enable or disable the namespace security for the NVM subsystems that is created on the storage system.
The namespace security is enabled by default if the namespace security (-namespace_security) is not specified when the NVM subsystem is created.
Changing the namespace security setting causes the following effects:
- When the namespace security is changed from Enable to Disable, any hosts that can access the NVM subsystem port in the Fibre Channel network level are permitted to access the NVM subsystem and the namespace to be changed.
- When the namespace security is changed from Disable to Enable, if a host NQN and a host-namespace path are not set for a host, the accesses from the host to the NVM subsystem and the namespace are disconnected and rejected.
