1.6 Discovering and Connecting to NVMe Devices on
OpenFlex Data24 4000 Series
This procedure will provide information on discovering and Connecting to NVMe devices on OpenFlex
Data24 4000 Series using the REST protocol over the data port. The IP address of the enclosure IOM may
be obtained using OCGUI or cURL. The IOM MAC address is available on the pull-out tab on the front of the
enclosure and on each of the IOMs at the rear of the system and can be used to determine the IP address.
Examples where REST commands are required will display cURL commands.
To find the drive NQN value using OCGUI, see: Obtaining the Drive NQN Value
Step 1 : Open a terminal and use the adapter's IPv4 or hostname address to discover all nvme devices
installed on the fabric.
sudo nvme discover -t rdma -a <IP of IOM Data Port>
Review the output to locate the subnqn number associated with the device that will be
Step 2 :
connected. The following example shows two devices, the In-Band management device, as well
as the device (SSD) intended for connection.
