NAME

       lfc_modreplica - modify information about a given replica

SYNOPSIS

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

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

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

DESCRIPTION

       lfc_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).

       lfc_modreplicax
	      is similar to lfc_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_MAXHOST-
		    NAMELEN.

       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.

NAME

       lfc_listreplicax - list replica entries for a given pool/server/filesystem

SYNOPSIS

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

       struct lfc_filereplica *lfc_listreplicax (const char *poolname, const char *server, const char *fs, int flags, lfc_list *listp)

DESCRIPTION

       lfc_listreplicax  lists	replica  entries for a given pool/server/filesystem.  This routine returns a pointer to a structure containing the
       current replica entry.

       struct lfc_filereplica {
	    u_signed64	   fileid;
	    u_signed64	   nbaccesses;
	    time_t	   atime;	  /* last access to replica */
	    time_t	   ptime;	  /* replica pin time */
	    char      status;
	    char      f_type;	     /* 'V' for Volatile, 'P' for Permanent */
	    char      poolname[CA_MAXPOOLNAMELEN+1];
	    char      host[CA_MAXHOSTNAMELEN+1];
	    char      fs[80];
	    char      sfn[CA_MAXSFNLEN+1];
       };

       poolname
	      specifies the disk pool (only meaningful for the DPM).

       server specifies the Storage Element or disk server hostname.

       fs     specifies the file system (only meaningful for the DPM).

       flags  may be one of the following constant:

	      CNS_LIST_BEGIN
		     the first call must have this flag set to allocate buffers and initialize pointers.

	      CNS_LIST_CONTINUE
		     all the following calls must have this flag set.

	      CNS_LIST_END
		     final call to terminate the list and free resources.

RETURN VALUE

       This routine returns a pointer to a structure containing the current replica entry if the operation was successful or NULL if  all  entries
       have been returned or if the operation failed. In the latter case, serrno is set appropriately.

EXAMPLES

       A C program listing the files residing on a given server could look like:

	    int flags;
	    lfc_list list;
	    struct lfc_filereplica *lp;

	    flags = CNS_LIST_BEGIN;
	    while ((lp = lfc_listreplicax (NULL, server, NULL, flags, &list))) {
		 flags = CNS_LIST_CONTINUE;
		 /* process the entry */
		 .....
	    }
	    (void) lfc_listreplicax (NULL, server, NULL, CNS_LIST_END, &list);

ERRORS

       ENOMEM	    Memory could not be allocated for the output buffer.

       EFAULT	    poolname, server and fs are NULL pointers or listp is a NULL pointer.

       EINVAL	    The length of poolname exceeds CA_MAXPOOLNAMELEN or the length of server exceeds CA_MAXHOSTNAMELEN or the length of fs exceeds
		    79.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.
