Troubleshooting guide

$ ./configure --with-linux=<linux-source-dir>

where <linux-source-dir> specifies the directory for the Linux kernel source. The kernel

header files MUST match the running kernel exactly: not only should they both be from

the same version, but they should also contain the same kernel configuration options.

Note:

• For Linux 2.6 kernels, the kernel headers/scripts often come in two parts in two

different directories, you might need to use both --with-linux and --with-linux-

build. For instance to select a specific kernel, you might need something like:

$ ./configure --with-linux=/usr/src/linux-2.6.5-7.151/ \

--with-linux-build=/usr/src/linux-2.6.5-7.151-obj/x86_64/smp/

By default, the mapper in MX is provided by the Fabric Management System

(FMS).

If you would like to use the diagnostic capabilities of FMS, you need to specify

the name of the FMS server (the node on which the fms process will be run) at

configure time, using --with-fms-server=<fms_server>.

$ ./configure --with-fms-server=<fms_server>

To defer this specification until install time, or to override it, you may install MX

with make install FMS_SERVER=<fms_server>.

For detailed installation instructions for MX with FMS diagnostic monitoring,

refer to the FMS webpage.

• If you would like to use the previous mapper, mx_mapper, you need to configure

with the option --disable-fms.

2. Installing the MX-2G mcp and 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 MX

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

make install script.

make install DESTDIR=<install_path>

If you omit DESTDIR=<install_path>, the mcp and driver will be installed in the

directory specified with the configure --prefix option, or the default directory, /opt/mx/.

The MX binaries are located in <install_path>/bin and <install_path>/sbin. The 32-bit
