NAME
     ha_gcd - group communication daemon

SYNOPSIS
     ha_gcd [ -hilV] [ -c conffile ] [ -n nodename  ] [ -p portno ] [ -s loglevel ] [ -L logpath ]

DESCRIPTION
     The Group Communication Daemon (ha_gcd) provides an atomic messaging
     service in a highly available cluster. This daemon is layered on top of
     the Cluster Membership Services Daemon (ha_cmsd), which presents a
     consistent view of node membership in the presence of node and network
     failures. The ha_gcd presents a consistent view of group memberships in
     the presence of process failures and changing node memberships.

OPTIONS
     The ha_gcd takes several options:

     -h          Display help message regarding ha_gcd options.

     -i          Run in independent mode: do not talk to ha_cmsd.

     -l          Run ha_gcd as a foreground process.

     -V          Output the version of this ha_gcd.

     -c conffile Read ha_gcd configuration from conffile database.

     -n nodename The nodename used by the ha_gcd process to connect to the
                 ha_cmsd, ha_srmd and ha_fsd processes.  This option can be
                 used to run multiple ha_gcd processes on a machine.  The
                 nodename argument corresponds to the virtual nodename used by
                 each ha_gcd process.

     -p portno   Set port number used by ha_gcd for inter ha_gcd communication
                 to portno.

     -s loglevel Set the log level of the messages logged to stderr to
                 loglevel.

     -L logpath  Set the log directory used by ha_gcd to log messages to
                 logpath.

FILES
     /var/cluster/ha/comm     Directory used to create communication files for
     ha_gcd clients.

     /var/cluster/ha/tmp     Directory used to create temporary ha_gcd dump
     files.
