DPNS_LISTREPSET(3) DPNS Library Functions DPNS_LISTREPSET(3) NAME
dpns_listrepset - list replica entries that belong to a given set SYNOPSIS
#include <sys/types.h> #include "dpns_api.h" struct dpns_filereplicax *dpns_listrepset (const char *setname, int flags, dpns_list *listp) DESCRIPTION
dpns_listrepset lists replica entries that belong to a given set. This routine returns a pointer to a structure containing the current replica entry. struct dpns_filereplicax { u_signed64 fileid; u_signed64 nbaccesses; time_t ctime; /* replica creation time */ time_t atime; /* last access to replica */ time_t ptime; /* replica pin time */ time_t ltime; /* replica lifetime */ char r_type; /* 'P' for Primary, 'S' for Secondary */ char status; char f_type; /* 'V' for Volatile, 'P' for Permanent */ char setname[37]; char poolname[CA_MAXPOOLNAMELEN+1]; char host[CA_MAXHOSTNAMELEN+1]; char fs[80]; char sfn[CA_MAXSFNLEN+1]; }; setname is either the replica set name or the space token. 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. ERRORS
ENOMEM Memory could not be allocated for the output buffer. EFAULT setname or listp is a NULL pointer. EINVAL The length of setname exceeds 36. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error. ENSNACT Name server is not running or is being shutdown. SEE ALSO

DPNS_MODREPLICA(3) DPNS Library Functions DPNS_MODREPLICA(3) 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_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. SEE ALSO
