4.3 Addressing

This section applies to the ibdiagpath tool only. A tool command may require defining

the destination device or port to which it applies.

The following addressing modes can be used to define the IB ports:

• Using a Directed Route to the destination: (Tool option ‘-d’)

This option defines a directed route of output port numbers from the local port to the destina-

tion.

• Using port LIDs: (Tool option ‘-l’):

In this mode, the source and destination ports are defined by means of their LIDs. If the fabric

is configured to allow multiple LIDs per port, then using any of them is valid for defining a

port.

• Using port names defined in the topology file: (Tool option ‘-n’)

This option refers to the source and destination ports by the names defined in the topology file.

(Therefore, this option is relevant only if a topology file is specified to the tool.) In this mode,

the tool uses the names to extract the port LIDs from the matched topology

, then the tool oper-

ates as in the ‘-l’ option.

4.4 Diagnostic Utilities

The diagnostic utilities described in this chapter provide means for debugging the connectivity

and status of InfiniBand (IB) devices in a fabric.

Utility Description

dump_fts Dumps tables for every switch found in an ibnetdiscover scan of the subnet.

The dump file format is compatible with loading into OpenSM using the -R

file -U /path/to/dump-file syntax.
