[SPDK] Re: Configuring SPDK NVMe over TCP initiator

Hi Chethan,

take a look at https://spdk.io/doc/nvmf.html <https://spdk.io/doc/nvmf.html> for setting up the NVMF and https://spdk.io/doc/bdev.html#bdev_config_nvme <https://spdk.io/doc/bdev.html#bdev_config_nvme> for setting up an NVMe bdev.

The basic steps are something like below (haven’t had a chance to verify these steps so they may need some adjustments):

Follow https://spdk.io/doc/system_configuration.html <https://spdk.io/doc/system_configuration.html> to set up the environment. Basically, you have to run scripts/setup.sh and ensure that the NVMe device is using the vfio-pci or uio_pci_generic (lspci -vv to verify or run the script again to give status).

Then create a bdev for the NVMe device and add it as a namespace to a NVMF subsystem:

scripts/rpc.py bdev_nvme_attach_controller -b NVMe1 -t PCIe -a 0000:01:00.0

scripts/rpc.py nvmf_create_transport -t TCP -u 16384 -m 8 -c 8192
scripts/rpc.py nvmf_create_subsystem nqn.2016-06.io.spdk:cnode1 -a -s SPDK00000000000001 -d SPDK_Controller1
scripts/rpc.py nvmf_subsystem_add_ns nqn.2016-06.io.spdk:cnode1 NVMe1
scripts/rpc.py nvmf_subsystem_add_listener nqn.2016-06.io.spdk:cnode1 -t rdma -a 192.168.100.8 -s 4420
