Hi All,

I am trying to configure iSCSI for a NVMe drive and getting the below error’s. I have unbound the NVMe drive from kernel using the setup.sh.

tgt_node.c: 718:spdk_iscsi_tgt_node_construct: ***ERROR*** Could not construct SCSI device
tgt_node.c: 984:spdk_cf_add_iscsi_tgt_node: ***ERROR*** tgt_node1: add_iscsi_target_node error
tgt_node.c:1010:spdk_iscsi_init_tgt_nodes: ***ERROR*** spdk_cf_add_iscsi_tgt_node() failed
iscsi_subsystem.c: 965:spdk_iscsi_subsystem_init: ***ERROR*** spdk_iscsi_init_tgt_nodes() failed
app.c: 404:spdk_app_init: ***ERROR*** spdk_subsystem_init() failed

Below is the section of my iscsi.conf.in <http://iscsi.conf.in/> file for reference.

# NVMe configuration options
# NVMe Device Whitelist
# Users may specify which NVMe devices to claim by their PCI
# domain, bus, device, and function. The format is dddd:bb:dd.f, which is
# the same format displayed by lspci or in /sys/bus/pci/devices. The second
# argument is a "name" for the device that can be anything. The name
# is referenced later in the Subsystem section.
# Alternatively, the user can specify ClaimAllDevices. All
# NVMe devices will be claimed and named Nvme0, Nvme1, etc.
# BDF 0000:00:00.0 Nvme0
  BDF 0000:0a:00.0 Nvme3

  TargetName disk2
  TargetAlias "Data Disk2"
  Mapping PortalGroup1 InitiatorGroup1
  AuthMethod Auto
  AuthGroup AuthGroup1
  UseDigest Auto
  LUN0 Nvme3
  QueueDepth 64

Thank you
