A list of available namespaces is displayed.
3. Select the check boxes next to the namespaces to map them to the host.
4. (Optional) To add or remove an NVMe drive namespace mapping, click the arrow of the host and select or de-select

Prerequisites
•
A supported Linux version.
•
The nvme command, available in the Open Source NVMe Management Utility-NVMe Command Line Interface (NVMe-
CLI).
•
A HostNQN, which is saved as a default setting in the file /etc/nvme/hostnqn. You can generate a random
HostNQN by entering the following command when logged in as root:
# nvme gen-hostnqn > etc/nvme/hostnqn
•
The SubsystemNQN, which is displayed in the DRIVES tab of the WebUI.
The Transport type is rdma.
•
•
The Transport address is the IP address of the bridge for the drive.
The drive must have at least one namespace that is mapped to a host on the WebUI HOSTS tab.
•
Procedure
1. Connect a host to drive in slot 1.
# nvme connect -t rdma -a <Bridge-IP-Address> -n nqn.nvme-subsystem:slot01
2. Verify that the drive is connected.
