# srp\_daemon\_port@.service(5)

srp\_daemon\_port@ systemd service that controls a single port

## NAME

srp\_daemon\_port@.service - srp\_daemon\_port@ systemd service that controls a single port

## SYNOPSIS

srp\_daemon\_port@.service

## DESCRIPTION

The srp\_daemon\_port@.service controls whether or not an srp\_daemon process is monitoring the RDMA port specified as template argument. The format for the RDMA port name is *dev:port* where *dev* is the name of an RDMA device and *port* is an port number starting from one. Starting an instance of this template will start an srp\_daemon process. Stopping an instance of this template will stop the srp\_daemon process for the specified port. It can be prevented that srp\_daemon is started for a certain port by masking the corresponding systemd service, e.g. **systemctl mask** **srp\_daemon\_port@mlx4\_0:1**.

A list of all RDMA device and port number pairs can be obtained e.g. as follows:

```
$ (cd /sys/class/infiniband >&/dev/null && for p in */ports/*; do
   [ -e "$p" ] && echo "${p/\/ports\//:}"; done)
mlx4_0:1
mlx4_0:2
mlx4_1:1
mlx4_1:2
```
