 NAME
      clusterconf - HP Cluster configuration file, cluster.h

 SYNOPSIS
      #include <sys/types.h>
      #include <cluster.h>

 DESCRIPTION
      The file /etc/clusterconf describes the membership of an HP cluster
      and is used by several library routines.  The file itself has the
      following format:

           Lines starting with # are comment lines.

           The first non-comment line should contain the link-level address
           of the cluster server followed by a colon (:) character.

           A description of each cluster node (detailed below).

      A cluster node is described by a series of colon (:) separated fields,
      terminated by a new-line character.  The fields are:

           machine ID     The ETHERNET address of the attached LAN card.
                          This is a 12-character hexadecimal number.

           cnode ID       An integer between 1 and 255 inclusive.  Used to
                          identify cnodes within a cluster.  Each entry in
                          /etc/clusterconf must have a unique cnode ID.  By
                          convention, the cnode ID of the cluster server is
                          1.

           cnode name     The name associated with this cnode of the
                          cluster.  The cnode name can be up to 8 characters
                          long.  Each entry in /etc/clusterconf must have a
                          unique cnode name.

           cnode type     A single character.  If this machine is the
                          cluster server, the cnode type is r; otherwise, it
                          is c.

           swap location  If this machine uses the cluster server's swap
                          space, swap location is the cnode ID of the
                          cluster server.  If swapping locally, swap
                          location is the cnode ID of the client machine.
                          If swapping through an auxiliary swap server, swap
                          location is the cnode ID of the auxiliary swap
                          server.

           csp            The default number of kernel-level server
                          processes to create when the csp command is
                          executed (see csp(1M)).  The number of CSPs

                          allowed on the system at any given time is limited
                          by the value of the HP-UX tuneable parameter
                          ngcsp.

      The file /etc/clusterconf is usually accessed by the routines
      getccent(), getccmid(), getccnam(), setccent(), endccent(), and
      fgetccent() (see getccent(3C)).

      The cct_entry structure defined in <cluster.h> is defined as follows:

           struct cct_entry {              /* cluster configuration table entry */
               u_char machine_id[M_IDLEN]; /* Machine ETHERNET address */
               cnode_t cnode_id;           /* cnode ID */
               char cnode_type;            /* 'r' for cluster server,
                                              'c' for all others */
               char cnode_name[15];        /* cnode name */
               cnode_t swap_serving_cnode; /* swap server location */
               int kcsp;                   /* default number of CSPs */
           }
