How to use "alter database create datafile ... as"?

Senario: file1 on disk1 is lost and not backed up.

I understand that if disk1 is lost, I should do: alter database create datafile '/disk1/file1' as '/disk2/newfile1';

but if disk1 is ok, can I use
alter database create datafile '/disk1/file1' as '/disk1/filel1';
