Add an NVMe target

Add an NVMe target (or SDT component) to PowerFlex.

Steps

  1. On the menu bar, click Block > NVMe Targets.
  2. Click + Add NVMe Target.
  3. In the Add NVMe Target dialog box, configure the following settings:
    1. For Target Name, enter a name for the NVMe target (or SDT component).
    2. For Protection Domain, select a protection domain.
    3. Accept the default TCP ports, or modify them if necessary.
      • Storage Port listens for incoming connections from the MDM, and is only open on an IP address configured with the storage role. Default=12200
      • I/O Port listens for incoming connections for I/O, and is only open on an IP address configured with the host role. Default=4420 (which conforms to the NVMe over TCP standard)
      • Discovery Port listens for incoming discovery connections, and is only open on an IP address configured with the host role. Default=8009 (which conforms to the NVMe over TCP standard. Use zero to disable the discovery service.)
    4. For Target IPs, enter an IP address, and then select a role for the IP address from the Target IPs Roles menu. Click Add Target IP, and repeat this step until all IP addresses are configured.
  4. Click Add.
  5. Verify that the operation has finished and was successful, and click Dismiss.

Description: Add an SDT
Parameters:
    --sdt_ip <IP>                       A comma separated list of IP addresses assigned to the SDT
