Dbverify in ASM - RAC

Question

Hi,
I have a production environment in RAC, and some indices appear as corrupt I would I rebuild up there and everything's fine. I want to make a dbverify to datafile that the indices have corrupt and verify that this well, the issue is that the storage is ASM then datafiles not see them by operating system.
This is the datafile:
system@saludwebrac-->select file_name, tablespace_name from dba_data_files
2 where tablespace_name = 'SALWEB_PEQ_IND';
FILE_NAME
+DGN_SALUDWEB/saludweb/datafile/salweb_peq_ind.272.637187829                           
system@saludwebrac-->
Thousand Thanks to who can help me!

There it is absolutely no problem with that. Since the datafile is within the ASM it can be seen, from the Oracle perspective, as a regular file, so the command dbv will work just the way it works with a regular file.
You must get the file name from either the v$datafile or dba_data_files view and perform the dbv session as usual. There is one thing, though, since the data files can only be "seen" from inside the ASM, you must open a session with a database user and password, that's what the USERID is for, and the rest you can use it as a regular dbv session:
Example:
SQL> select name from v$datafile;
NAME
