Not sure I understand the question. When using RAW devices, you specify the OS device/ volume name to Oracle. For example:

ALTER TABLESPACE ADD DATAFILE '/dev/vx/rdsk/DG01/orcl_system_01' SIZE ...;


Oracle will format the file while adding it.

For RAC to work, these devices/ volumes must be visible from all nodes of the cluster.

Best regards.

Frank
