4.6.3 Discovering and Connecting to NVMe™ Devices on OpenFlex
Data24 3200
This procedure will provide information on discovering and Connecting to NVMe devices on OpenFlex
Data24 3200 using the REST protocol over the 1Gb Management Port. This process assumes the user
knows the IP address of the 1 Gb Ethernet Management port of the enclosure IOM. The IOM MAC address
is available on the pull-out tab located 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.
Open a terminal and use the adapter's IPv4 address to discover all nvme devices installed on
Step 1 :
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.

port information to determine protocol being used. When configuring RoCE, PFC
flow control is automatically enabled. When configuring TCP, Global Pause flow
control is automatically enabled.
