why i get the fail tips in the end of restore database?

i use rman backup and restore to build dataguard environmen.

i run all operators in primary site,e.g:

1) backup primary database;

2) copy backup set to slave site;(use scp utilize)

3) restore slave database in primary site, i use down cmd:

-- login primary site

# su - oracle

# rman target sys/xxx@drora11g  --- drora11g is the tnsname for slave database

RMAN> run

{

    restore standby controlfile from '/home/oracle/archive/orabackup/stbcontrolfile';

    alter database mount;

    restore database;

}
