You can set the host access permission (set a host-namespace path) to a namespace using the host NQN that has been set for the NVM subsystem. A specific host can access a specific namespace by specifying whether the host can access the namespace. When multiple hosts share the NVM subsystem, you can set the allocation of the namespace to the hosts in detail.
When the namespace security for the NVM subsystem is enabled, the host cannot access the logical volume even if a logical volume is added to the NVM subsystem as a namespace. Specify the host NQN and the namespace that are set on the NVM subsystem, and then configure the host-namespace path.
When the namespace security for the NVM subsystem is disabled, any host can access all namespaces on the NVM subsystem regardless of the access settings for the host in the namespace.
Ensure that these prerequisites are met:
- The NVM subsystem is created.
Verify the NVM subsystem ID.
- A host NQN is created on the NVM subsystem.
- A namespace is created on the NVM subsystem.
- A logical volume is created.
Verify the namespace ID of a logical volume used by the host.
