restoring quorum after array and logical drive repartitioning

    Ok, I am running out of space on some of my logical drives on my HP MSA1000.
    The previous setup(not by me) partioned 6 logical drives in a single array,
    with the quorum drive being on a logical drive in that array.

    I've removed SQL and moved it to a new cluster(Yea!!!!), but Exchange still
    runs on this cluster, and will remain on this cluster until Exchange 2007
    rolls out and we replace the hardware with 64-bit servers. Unfortunately,
    I'm running out of space on the logical drives assigned to Exchange. With
    SQL no longer on the cluster, I have plenty of "theoretical" space, but I'd
    need to rearrange logical drive sizes.

    It doesn't appear that I can shrink existing arrays and logical drives in
    the HP Array Utility, so I'm thinking that it may be easier to shutdown the
    cluster/Exchange services, backup the Exchange edb files and the system
    state/quorum, destroy the exiting array config, re-config a smarter array
    with bigger partitions, restore the data and quorum, and hopefully restart
    the cluster services.

    Is this possible or am I setting myself up for disaster?

    It sounds good, but i would prefer a different way:

    1st, perform Backup. Because you have a single array with multiple
    logical drives you could delete the only the sql logical drive (and all
    other that you not need). After that, you have free space in the array
    and are able to extend the exchange volume (online!). Perform a Disk
    rescan and extend with diskpart (MS Tool from Reskit) the partition.

    I thought of that, but the last time I extended a partition it took
    FOREVER(literally 6-8hrs overnight).....I was hoping that this would be a
    faster solution.

    strange, it is a very long time, was this a extension with shrinking a
    exisiting partion? Because you extent in my way to a new free disk
    location the duration is ma. 2 minutes!) but your system is online
    during the process you have not service interruption. Did you perform
    the partition extending with diskpart.

  6. You will also need to save/restore each disk's signature to the new disks or
    cluster will not work properly.

    got a link to a document for performing the disk signature backups?
