NAME

       opafabricinfo

       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(R) 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, opareports, and opatop. These tools can
       be found in the Intel(R) Omni-Path Fabric Suite FastFabric User Guide

Syntax

       opafabricinfo [-t  portsfile] [-p  ports]

Options

       --help

                 Produces full help text.

       -t portsfile

                 Specifies the file with list of local HFI ports used  to  access  fabric(s)  for
                 analysis. Default is /etc/opa/ports file.

       -p ports

                 Specifies the list of local HFI ports used to access fabrics for analysis.

                 Default  is  first active port. The first HFI in the system is 1. The first port
                 on an HFI is 1. Uses the format hfi:port,
                 for example:

                 0:0       First active port in system.

                 0:y       Port y within system.

                 x:0       First active port on HFI x.

                 x:y       HFI x, port y.

Environment Variables

       The following environment variables are also used by this command:

       PORTS

                 List of ports, used in absence of -t and -p.

       PORTS_FILE

                 File containing list of ports, used in absence of -t and -p.

                 For simple fabrics, the Intel(R) 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:

                 •      On the command line using the -p option.

                 •      In a file specified using the -t option.

                 •      Through the environment variables PORTS or PORTS_FILE.

                 •      Using the ports_file configuration option in opafastfabric.conf.

                 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.

Example

       opafabricinfo

       opafabricinfo -p '1:1 1:2 2:1 2:2'

       Output example

       # opafabricinfo

       Fabric 0:0 Information:

       SM: hds1fnb6241 hfi1_0 Guid: 0x0011750101575ffe State: Master

       Number of HFIs: 8

       Number of Switches: 1

       Number of Links: 8

       Number of HFI Links: 8              (Internal: 0 External: 8)

       Number of ISLs: 0                   (Internal: 0 External: 0)

       Number of Degraded Links: 0         (HFI Links: 0 ISLs: 0)

       Number of Omitted Links: 0          (HFI Links: 0 ISLs: 0)

Output Definitions

       SM

                 Each  subnet  manger  (SM)  running  in the fabric is listed along with its node
                 name, port GUID, and present SM state (Master, Standby, etc.).

       Number of HFIs

                 Number of unique host fabric interfaces (HFIs) in the fabric.  An  FI  with  two
                 connected ports is counted as a single FI.

       NOTE: Fabric Interfaces include HFIs in servers as well as HFIs within I/O Modules, Native
       Storage, etc.

       Number of Switches

                 Number of connected switches in the fabric.

       Number of Links

                 Number of links in the fabric. Note that a large switch may have internal links.

       Number of HFI Links

                 Number of HFI links (Internal and External) in the fabric.

       Number of ISLs

                 Number of Interswitch Links (Internal and External) in the fabric.

       Number of Degraded Links

                 Number of degraded links (HSI and ISL) in the fabric.

       Number of Omitted Links

                 Number of omitted links (HSI and ISL) in the fabric.
