    cluster enabled existing pool/volume


    please forgive me if this is not the correct forum for this type of
    question. I will be adding an existing stand alone server (nw65, sp3)
    to a cluster (NCS1.7). I am looking for a TID that would show me how to
    convert existing pools/volumes on that stand alone server to cluster
    resoures (after I add it to the cluster). have been searching the
    knowledgebase but so far no luck. If anyone know of a TID, please post
    the URL. Thanks in advance.

    I don't know if you are in the correct one, but here is the answer

    you can only set a Device for Cluster Shareable. If this Device
    contains the SYS Volume it isn't possible.

    Here the part of the Docu:

    " If this device is a member of a software RAID device, marking a
    device
    as shareable for clustering also sets all the other member devices
    as shareable for clustering.
    Guidelines for Making Devices Shareable
    Do not assign a device as Shareable for Clustering if it is not
    capable of being shareable.

    If you create a pool that spans multiple storage devices, each of
    the member devices in that pool must either be marked as Shareable
    for Clustering or as Not Shareable for Clustering.

    The sys: pool and all of its member devices cannot be marked as
    Shareable for Clustering.

    Devices that contain Traditional segments and volumes cannot be
    marked as Shareable for Clustering.

    If you assign segments to a software RAID device, all the devices
    for those member segments must either be marked as Shareable for
    Clustering or as Not Shareable for Clustering.

    Hope this helps
