Host List Files
The /etc/sysconfig/iba/hosts and /etc/sysconfig/iba/allhosts
files are used to specify the hosts which Fast Fabric will operate against for many
operations.
If desired alternate filenames may be specified in fastfabric.conf, via
environment variables or on the command line. Refer to the section “Selection of
Hosts” on page 5-3 for more information.
Below is a sample host list file:
# this is a comment
192.168.0.4# host identified by IP address
n001# host identified by resolvable TCP/IP name
include /etc/sysconfig/iba/hosts-mpi# included file
Each line of the host list file may specify a single host, a comment or another host
list file to include.
Hosts may be specified by IP address or a resolvable TCP/IP hostname. Typically
hostnames are used for readability. Also, some Fast Fabric tools will translate the
supplied host names to IPoIB hostnames, in which case names are generally easier
to translate than numeric IP addresses. Typically management network host names
are specified. However, if desired, IPoIB hostnames or IP addresses may be used.
This can accelerate large file transfers and other operations.
Files to be included may be specified via an include directive followed by a file
name. File names specified should generally be absolute path names. If relative
path names are used, they will be searched for within the current directory then
/etc/sysconfig/iba.
Comments may be placed on any line by using a # to precede the comment. On
lines with hosts or include directives, the # must be white-space separated from
any preceding host name, IP address or included file name.

Chassis List Files
The /etc/sysconfig/iba/chassis and
/etc/sysconfig/iba/esm_chassis files are used to specify the SilverStorm
IB chassis that Fast Fabric will operate against for many operations.
If desired alternate filenames may be specified in fastfabric.conf, via
environment variables or on the command line. Refer to the sectoin “Selection of
Chassis” on page 5-4 for more information.
