NAME

       clusters - cluster names database

SYNOPSIS

       /etc/clusters

DESCRIPTION

       The  clusters  file contains information regarding the known clusters in the local naming domain.  For each cluster a single line should be
       present with the following information:

	 clustername	     whitespace-delimited list of hosts

       Expansion is recursive if a name on the right hand side is tagged with the expansion marker: ``*''.

       Items are separated by any number of blanks and/or TAB characters.  A `#' indicates the beginning of a comment. Characters up to the end of
       the line are not interpreted by routines which search the file.

       Cluster names may contain any printable character other than an upper case character, a field delimiter, NEWLINE, or comment character. The
       maximum length of a cluster name is 32 characters.

       This information is used by Sun Cluster system administration tools, like cconsole(1M) to specify a group  of  nodes  to  administer.   The
       names used in this database must be host names, as used in the hosts database.

       The database is available from either NIS or NIS+ maps or a local file.	Lookup order can be specified in the /etc/nsswitch.conf file.  The
       default order is nis files.
