Provides a brief summary of the components in the fabric, using the first active port on the given local host to perform its analysis. opafabricinfo is supplied in both:
Intel® Omni-Path Fabric Suite FastFabric Toolset
In this situation, the command can manage more than one fabric (subnet).
FastFabric Tools
In this situation, the command performs analysis against the first active port on the system only. It takes no options and uses no environment variables.
opafabricinfo can be very useful as a quick assessment of the fabric state. It can be run against a known good fabric to identify its components and then later run to see if anything has changed about the fabric configuration or state.
For more extensive fabric analysis, use opareport and opareports. Also see opatop in the Intel® Omni-Path Fabric Suite FastFabric User Guide.
Specifies the list of local HFI ports used to access fabrics for analysis.
The following environment variables are also used by this command:
File containing list of ports, used in absence of -t and -p.
For simple fabrics, the Intel® Omni-Path Fabric Suite FastFabric Toolset host is connected to a single fabric. By default, the first active port on the FastFabric Toolset host is used to analyze the fabric. However, in more complex fabrics, the FastFabric Toolset host may be connected to more than one fabric or subnet. In this case, you can specify the ports or HFIs to use with one of the following methods:
If the specified port does not exist or is empty, the first active port on the local system is used. In more complex configurations, you must specify the exact ports to use for all fabrics to be analyzed.
opafabricinfo opafabricinfo -p '1:1 1:2 2:1 2:2'
