ORA-15001: diskgroup "DATAC1" does not exist or is not mounted | encountered while duplicate command for standby

     I am creating standby database using duplicate command. i encountered ORA-15001 error for password file modification, but error saying DATAC1 disk group does not exists, this error message is misleading and not recognizable.

After contacting oracle, its identified that its an issue with password file update by oracle.  

RMAN command used:

duplicate target database for standby from active database nofilenamecheck;

Error message:

sql statement: alter system set  control_files =   ''+DATAC1/XYZ/CONTROLFILE/current.274.1174401739'' comment= ''Set by RMAN'' scope=spfile
