An administrator is connecting a Linux host to a PowerStore appliance and must know which storage network interface to use. Which nvme subcommand should be used?

Question

Options

• Aconnect
• Bid-ccrl
• Cattach-ns
• Ddiscover

• A

• B
  2% (1)
• C
  7% (4)
• D
  88% (50)

Explanation

nvme discover is correct because it queries the Discovery Controller on the fabric network to enumerate available NVMe-oF targets and their transport addresses (IP, port, NQN), which is exactly how an administrator identifies which network interface a PowerStore appliance is advertising before making a connection.

Why the distractors are wrong:

• A. connect - Used after discovery; it establishes a session to a known target but requires you to already know the interface address.
• B. id-ccrl - Not a standard nvme-cli subcommand; likely a distractor mimicking id-ctrl (identify controller), which interrogates an already-connected controller.
• C. attach-ns - Attaches a namespace to a controller after a connection exists; it has nothing to do with finding network interfaces.

Memory tip: Think D for Detect - discover is the detection step that reveals what's out there on the network, just like a network scan before you log in. Connect comes after discovery, so the order is always Discover → Connect.
