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.
