I've lost a san and had local controlfiles.
From them I was able to ascertain where the files were so that when the SAN was rebuilt (which in this case it had to be), we knew exactly what directories needed to be restored (which our san admins had no idea - shame on them).
You could also ascertain, from the controlfiles, what your recovery options are BEFORE restoring from backup, which could save some time. RMAN should still come up!

I don't understand what good it does to have the control file alone on your local disk in that situation? If your SAN with the rest of your database files is toast, then your control file alone isn't going to do you much good. You're going to have to restore from a backup and do an incomplete recovery anyway, so what's the difference if you do it with your current controlfile still on your local disk, or if you restore a control file from backup along with the rest of the database files you'll be restoring?

Good luck convincing anyone that you NEED two mirrored fast local
drives,
but maybe this will help:
