clusters(4)			     Sun Cluster File Formats			      clusters(4)

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  rou-
       tines 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.
