Install nvme-cli tool

The NVMe management command line interface tool is required on the host to connect to an NVMe target. If the tool is not installed, install the nvme-cli package using the yum command.

[root@splk-ix01 ~]# yum -y install nvme-cli

For the host to communicate with another NVMe device, it must have a unique identity known as NVMe Qualified Name or NQN. If the host doesn’t have one, it must be created. Check if a host nqn exists using the following command.

[root@splk-ix01 ~]# cat /etc/nvme/hostnqn
nqn.2014-08.org.nvmexpress:uuid:4c4c4544-0030-4410-8039-c3c04f483133

If the hostnqn doesn’t exist, create the directory /etc/nvme and use the nvme gen-hostnqn command to add an id to a file named hostnqn in the /etc/nvme directory. This hostnqn is needed when creating a host in the FlashArray.

[root@splk-ix01 ~]# mkdir -p /etc/nvme
[root@splk-ix01 ~]# nvme gen-hostnqn > /etc/nvme/hostnqn
[root@splk-ix01 ~]# cat /etc/nvme/hostnqn
nqn.2014-08.org.nvmexpress:uuid:4c4c4544-0030-4410-8039-c3c04f483133
