 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.
