ASM files can be renamed like any other files in a standard filesystem. For ASM, rename is peformed through some type of statements (ADD ALIAS, RENAME ALIAS, ADD DIRECTORY) to manipulate filenames, alias, and directories.
Renaming datafiles is sometimes needed when database file names still contains old database name after a database on ASM is renamed (for example with nid). Then, it is required to change ASM datafile names accordingly with new database name. RMAN backup copy doesn't work in this case as file still remains in the same diskgroup.
