Also, some Fast Fabric tools willtranslate the supplied host names to IPoIB hostnames, in which case names aregenerally easier to translate than numeric IP addresses. Typically managementnetwork hostnames are specified. However, if desired, IPoIB hostnames or IPaddresses may be used. This can accelerate large file transfers and otheroperations.Files to be included may be specified via an include directive followed by a filename. File names specified should generally be absolute pathnames. If relativepathnames 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 separatedfrom any preceding hostname, IP address or included file name.5.1.6.2Explicit host namesWhen hosts are explicitly specified via the -h option or the HOSTS environmentvariable, a space separated list of host names (or IP addresses) may be supplied.For example: -h 'host1 host2 host3'.5.1.7Selection of ChassisFor operations which are performed against a set of chassis, there are multipleways to specify the chassis on which to operate:
