Host List Files
The /etc/sysconfig/iba/hosts and /etc/sysconfig/iba/allhosts files are
used to specify the hosts which FastFabric will operate against for many
operations.
If desired alternate filenames may be specified in
fastfabric.conf, using
environment variables or on the command line. Refer to FastFabric Command
Line Interface Reference Guide for more information.
Below is a sample host list file:
# [ICS VERSION STRING: @(#) ./fastfabric/ib_tools/allhosts x_x_x_x_x [MM/DD/YY hh:mm]
# This file lists the TCP/IP names of ALL the hosts in the cluster.
# THIS SHOULD INCLUDE THE NODE RUNNING FASTFABRIC
#
# If Ethernet is being used for the management network, specify
# the hostname corresponding to the ethernet IP address.
# This file will be used by FastFabric to indicate which hosts should be
# operated on by various fastfabric menus and CLI commands.
include /etc/sysconfig/iba/hosts
# add line below with TCP/IP name of FastFabric host (eg. this host)
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 FastFabric 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 using 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.
