    We are trying to install SQL on our three-node Windows
    2003 Server cluster. We are using Majority Node Set
    because we do not have a physical disk attached to use as
    the quoram resource. When we try to install SQL and we
    get to the part of the installation process where it asks
    you to "select a cluster disk where data files will be
    placed", there is nothing listed. Is it possible to set
    up SQL on a cluster using MNS?

  2. MNS & SQL is not supported. Sorry. Think 3rd party.

  3. SQL requires shared disk(s) for the database and logs.

  4. Drew,

    Consider MNS as a new "quorum type" i.e. quorum resource can be either of
    type "Majority Node Set" or of type "Physical Disk".

    Even though for a MNS based cluster you do not need a shared disk (more
    appropriately - a resource of type "Physical Disk") for quorum, you will
    still need shared disks for resources of other types like Exchange, SQL,
    File Share etc.

    I would be interested to know your references that SQL and
    MNS are not supported. We are currently running SQL 2000
    with Windows Server 2003, Enterprise and using the MNS.
    I have not run into a problem as yet... but would like to
    know for further/future reference. Thanks

  6. I can't find anything on the web that states one way or the other. Though I
    can not find a single article that says anything about SQL & MNS. I first
    heard it from several Microsoft employees. Maybe one will chime in here.

  7. I would point to th fact that with two servers in a cluster, the cluster can
    not survive a single failure because majority can not be reached. In a two
    node cluster, a single node failure will result in a complete failure.

    I would also point the fact that SQL requires a shared disk for the
