ASM 10.2.0.4 disk header question - f1b1

I have played around with the ASM disk header and kfed in an effort to rename a disk group in 10.2.0.4 (Linux). I achieved to do this roughly in the same way as the new 11.2 renamedg tool works.

One question remains: does anyone know the meaning/importance of the f1b1 item? I.e. what significance does the following line have in a disk header?

kfdhdb.f1b1locn:                      2 ; 0x0d4: 0x00000002

I've seen at least 1 disk in a disk group had this set to 2, whereas all the others had it set to 0.

Any ideas? It doesn't seem to be (publicly) documented anywhere, it might be in (internal) Note.417687.1 ***INTERNAL NOTE*** Creating a New ASM Disk Header After Existing One Is Corrupted

Any help appreciated!
