LEARN ABOUT OPENSOLARIS

chosts

chosts(1M)						  System Administration Commands						chosts(1M)

NAME

       chosts - expand cluster names into host names

SYNOPSIS

       $CLUSTER_HOME/bin/chosts name [name...]

DESCRIPTION

       The chosts utility expands the arguments into a list of host names.

OPERANDS

       The following operands are supported:

       name		   The parameter name can be a hostname or a cluster name. If name is a hostname, it is expanded to be a hostname. If name
			   is a cluster name, that is, an entry exists in the /etc/clusters database (or a NIS or NIS+ map), it is  expanded  into
			   the	list of hosts that make up that cluster, as specified in the database. The list is typically used by programs that
			   wish to operate on a list of hosts.

			   If an entry for clusters has been made in the /etc/nisswitch.conf file, then the order of lookups is controlled by that
			   entry. If there is no such file or no such entry, then the nameservice look up order is implicitly nis files.
