Open Fabrics InfiniBand Diagnostic Utilities
--------------------------------------------
*******************************************************************************
RELEASE: OFED 1.4.1
DATE: May 2009
===============================================================================
Table of Contents
===============================================================================
1. Overview
2. New features
3. Major Bugs Fixed
3.1 Changes since OFED 1.4
4. Known Issues
===============================================================================
1. Overview
===============================================================================
The ibutils package provides a set of diagnostic tools that check the health
of an InfiniBand fabric.
Package components:
ibis: IB interface - A TCL shell that provides interface for sending various
MADs on the IB fabric. This is the component that actually accesses
the IB Hardware.
ibdm: IB Data Model - A library that provides IB fabric analysis.
ibmgtsim: An IB fabric simulator. Useful for developing IB tools.
ibdiag: This package provides 3 tools which provide the user interface
to activate the above functionality:
- ibdiagnet: Performs various quality and health checks on the IB
fabric.
- ibdiagpath: Performs various fabric quality and health checks on
the given links and nodes in a specific path.
- ibdiagui: A GUI wrapper for the above tools.
===============================================================================
2. New Features
===============================================================================
* Mellanox InfiniScaleIV support:
- Support switches with port count > 32
- Added ibnl (IB network) files for MTS3600 and MTS3610 InfiniScaleIV based switch systems.
* IBDM QoS Credit Loop check:
This check now considers SL/VL when looking for credit loops.
This check can be activated by running "ibdiagnet -r"
* ibdiagnet: Added -csv flag, which generated a set of Comma Separated Values
files, which contains data about the fabric. Generated files:
inv_csv - Lists the ports found in the fabric
links_csv - Lists the ports connections in the fabric
pm_csv - Lists port counters in csv format
err_csv - Lists errors found during the run
* ibmgtsim: Add basic M_Key mechanism simulation
===============================================================================
3. Major Bugs Fixed
===============================================================================
* ibdm: Support 2 port switches in a loaded LST file.
* ibis: fix some buffer overrun bugs with long node description.
* Installation: Ibdiagui requires tcl/tk 8.4 or 8.5 (was only 8.4). This allows
installation on Fedora Core 9.
* ibdiagnet: Fixed -pm flag caused a crash on back to back (no switch) setup.
* ibdiagnet: Do not query port counters when local port is in INIT state.
===============================================================================
3.1 Changes since OFED 1.4
===============================================================================
* PM csv files format fix
* Fixed generating and parsing IBNL files
* Fixed CC packet format to meet IBTA approved format
* Set of changes to sync with OpenSM changes
* Regenerated wrappers - fixed compilation errors on some distros
* Fixed printing SM and mcast info in ibdiagnet
* Other minor fixes/improvements
===============================================================================
4. Known Issues
===============================================================================
- Ibdiagnet "-wt" option may generate a bad topology file when running on a
cluster that contains complex switch systems.
- When a subnet manager is not running, ibdiagnet IPoIB check may take a long
time to complete.
