Troubleshooting guide

If you would like to have FMS diagnostic monitoring with GM-2, refer to the FMS
Download page (http://www.myri.com/scs/fms/) for installation instuctions.
If you are building GM-2 on SuSE SLES9 on PowerPC64 or AMD64 or EM64T, you
may need to explicitly point configure at the kernel source and object trees. For example,
./configure --with-linux=/lib/modules/`uname -r`/source --with-
linux-build=/lib/modules/`uname -r`/build
For more details on building GM-2 on AMD64 or EM64T, refer to "How do I build GM-
2 on AMD64 or EM64T?" (http://www.myri.com/cgi-bin/fom?file=252).
For more details on building GM-2 on PowerPC64, refer to "How do I build GM-2 on
PowerPC64?" (http://www.myri.com/cgi-bin/fom?file=260).
2. Installing the GM-2 driver.
Select an installation directory path <install_path>. It is usually best for <install_path>
to be the path to an NFS directory available on all machines that are to share this GM
installation. The directory must be accessible using <install_path> on all machines that
are to share the installation. <install_path> must be an absolute path; it must start with /.
However, <install_path> may contain symbolic links.
Note: The <install_path> installation directory must be created prior to invoking the
GM_INSTALL script.
cd binary
./GM_INSTALL <install_path>
If you omit <install_path>, the driver will be installed in the default directory, /opt/gm/.
Next, you must run
su root
<install_path>/sbin/gm_install_drivers
/etc/init.d/gm start
echo <install_path>/lib64 >> /etc/ld.so.conf
echo <install_path>/lib >> /etc/ld.so.conf && /sbin/ldconfig
on each machine.
When the hardware is connected through a cable to another operating component and the
GM-2 firmware has been loaded, a green “link” LED and a yellow/amber “Lanai” LED
will illuminate on NICs and a green “link” LED will illuminate on connected ports on the
line cards (on the TFT display). If you do not see a green “link” LED illuminated on a
component (port on a NIC or port on a switch line card), refer to the following
diagnostics:
