Subnet Management Agent

and unmounted when the infinipath script is invoked with the "stop" option (e.g. at system shutdown).

The layout of the filesystem is as follows: atomic_stats

00/

01/

...

The atomic_stats file contains general driver statistics. There is one numbered directory per InfiniPath device on the system. Each numbered directory contains the following files of per-device statistics:

atomic_counters node_info port_info

The atomic_counters file contains counters for the device: examples would be interrupts received, bytes and packets in and out, and so on. The node_info file contains information such as the device’s GUID. The port_info file contains information for each port on the device. An example would be the port LID.

2.4.5

Each node in an InfiniPath cluster runs a Subnet Management Agent (SMA), which carries out two-way communication with the Subnet Manager (SM) running on one or more managed switches. The Subnet Manager is responsible for network initialization (topology discovery), configuration, and maintenance. The Subnet Manager also assigns and manages InfiniBand multicast groups, such as the group used for broadcast purposes by the ipath_ether driver. The primary functions of the SMA are to keep the SM informed whether a node is alive and to get the node’s assigned identifier (LID) from the SM.

2.4.6

Layered Ethernet Driver

The layered Ethernet component ipath_ether provides almost complete Ethernet software functionality over the InfiniPath fabric. At startup this is bound to some Ethernet device ethx. All Ethernet functions are available through this device in a transparent way, except that Ethernet multicasting is not supported. Broadcasting is supported. You can use all the usual command line and GUI-based configuration tools on this Ethernet. Configuration of ipath_ether is optional.

These instructions are for enabling TCP-IP networking over the InfiniPath link. To enable IPoIB networking, see section 2.4.7.1.
