When using the "effects-log" command in nvme-cli without specifying the "csi" argument, a default action is added to check the ctrl register, allowing only character devices like nvme0. In older versions of nvme-cli, the default value of csi was set to 0 and issued without any problems But it has been fixed now. It can be used regardless of the version when used as a character device. Reference: linux-nvme/nvme-cli#2742 Signed-off-by: Steven Seungcheol Lee <[email protected]>
