Clusterware reaction when Failure group unavailable in extended cluster

Hi,

does anybody know how the clusterware will react in the following situation

Situation: (see below and attachment)

- extended cluster (SITE A and SITE using ASM mirroring (normal redundancy)

- 3 voting disks: 1 on SITE A, 1 on SITE B and 1 on NFS

- 2 failure groups: 1 on every site

Then a storage network split occurs SITE A only sees DATA failuregroupA and 2 voting disks

and SITE B only sees DATA failuregroupB and 2 voting disks.

So both sites see a majority of the voting disks

Normal Situation

    SITE A        -------  Interconnect  ----------  SITE B

      |                                                             |

      |  ----------------  NFS Voting Disk ------------    |

      |                                                             |

      ----------------  STORAGE NETWORK -----------

      |                                                             |

    Voting disk                                                 Voting Disk
