Q
If a relative path is specified for the -f option or HOSTS_FILE, the current
directory will be checked first, followed by /etc/sysconfig/iba/
5.1.6.1.1
Host List File Format
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 host name.
Typically, host names 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 hostnames 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 pathnames. If relative
pathnames 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 hostname, IP address or included file name.
5.1.6.2
Explicit host names
When hosts are explicitly specified via the -h option or the HOSTS environment
variable, a space separated list of host names (or IP addresses) may be supplied.
For example: -h 'host1 host2 host3'.

Selection of Chassis
For operations which are performed against a set of chassis, there are multiple
ways to specify the chassis on which to operate:
