NAME

       dpns_modreplica - modify information about a given replica

SYNOPSIS

       #include <sys/types.h>
       #include "dpns_api.h"

       int  dpns_modreplica  (const  char  *sfn, const char *setname, const char *poolname, const
       char *server)

       int dpns_modreplicax (const char *sfn, const char *setname, const  char  *poolname,  const
       char *server, const char *fs, const char r_type)

DESCRIPTION

       dpns_modreplica modifies information about a given replica.

       sfn    is either the Site URL or the Physical File Name for the replica.

       setname
              is either a replica set name or a space token.

       server is either the Storage Element fully qualified hostname or the disk server.

       poolname
              specifies  the  disk  pool name (this argument is only meaningful for the Disk Pool
              Manager).

       dpns_modreplicax
              is similar to dpns_modreplica but has the additional arguments:

       fs     specifies the mount point of  the  dedicated  filesystem  (this  argument  is  only
              meaningful for the Disk Pool Manager).

       r_type may be one of the following:

              P      Primary

              S      Secondary.

RETURN VALUE

       These  routines return 0 if the operation was successful or -1 if the operation failed. In
       the latter case, serrno is set appropriately.

ERRORS

       ENOENT       The named replica does not exist.

       EACCES       Search permission is denied on a component of the  parent  directory  or  the
                    effective  user ID does not match the owner of the file or read permission on
                    the file entry itself is denied.

       EFAULT       sfn is a NULL pointer.

       EINVAL       The  length  of  setname  exceeds  36,  the  length   of   poolname   exceeds
                    CA_MAXPOOLNAMELEN or the length of server exceeds CA_MAXHOSTNAMELEN.

       ENAMETOOLONG The length of sfn exceeds CA_MAXSFNLEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT      Name server is not running or is being shutdown.
