Adding x64 bit Win2003 node to existing 32 bit Win2003 MSCS

    Hi all,
    I am in a bit of a PANIC about a thread I have been pursuing on the SQL
    Server.clustering newsgroup. I am upgrading an existing MSCS cluster running
    on two Dell PE 6650's with Win2003 SP1 32-bit edition. The two nodes are to
    be replaced by two Dell PE 6850's with Win2003 x64 (NOT ITANIUM). My plan
    for doing this was to failover to one of the existing nodes, evict the other
    existing node, add one of the new nodes, lather, rinse and repeat. (More
    details are given in the thread below.) My consultant on the newsgroup, who
    is extremely reputable in the SQL server community, informs me this is
    IMPOSSIBLE. I would greatly appreciate it an expert reply from someone in
    this community. Thanks.


    Yes. You can't cluster 32 and 64 bit systems together. The drivers are not
    interchangable. The on-disk SQL data files are identical, but not much else

    One more clarification...
    TechNet has an article at the following URL:

    The title is "The addition of a 64-bit node to a 32-bit cluster is not

    Reading the 2nd Analyze phase error message (that one is always the
    heartbreaker, isn't it?), one sees "A cluster can only be created using nodes
    that have the same processor architecture. Your cluster has a "Intel x86"
    processor and the node you attempted to add has a "Intel Itanium" processor.
    Remove "" from the nodes list and try again." To
    me this implies an obvious incompatiblity with the IA64 processor. However,
    my plan is to use the x64 OS on a machine with XEON processors, which retain
    compatiblity with the x86 architecture. My sense is that this article does
    NOT apply to my situation and I should be OK. I would love to hear that I am

  3. John,

    You cannot add a 64-bit machine to a 32-bit cluster. This applies to both
    x64 and IA-64 processors.

    Thanks John. Are you by any chance a USMA grad from 79?

  7. Well now that Liam isn't on the list, I thought it would be safe ;-)

  8. We still have Russ, so they are not on the hook!
