Thanks dave....

The file_names are quite similar,
like 'u01/oradata/PROD/index01.dbf',
but when you go to this dir, i get
$ cd /u01/oradata/PROD
ls -l
index01.dbf -> lvora021

he used ln -s command here.
should it be on both nodes?

I guess raw device was used. I just dont know how to
account/inventory all those used and unused raw devices since u cant see them. I also remember that u have to used the character raw dev
agains block raw dev.

Can u pls give me links to docs on how to create/configure
raw devices/shared disk for RAC set-up?


Thanks a lot
