    Raid 1 for spanned hard drives possible?

    I inherited a client that has the following setup :
    SBS 2003 standard sp2
    Dell CERC ATA Raid Controller

    It has 2 drives : 1 is a simple 80GB drive partitioned into C and D;
    the other drive is 150GB dynamic spanned to the D.



    Can I put in another 250GB drive and mirror it to the existing
    partitions?
    TIA

    I doubt it, but even if you could, I'd strongly discourage it. IDE drives
    were never designed for server use because ATA as a protocol is not robust.
    SCSI has a long heritage of being very intelligent, so it (or SAS) lends
    itself very well to RAID.

    The setup you describe, with a span that you'd then be trying to mirror,
    would probably crush your performance on simple IDE drives.

    These are SCSI drives

    If you want to make your life simple, install another raid controller
    and install two drives in a raid 1 on it.

    I can't directly answer your question, but, I'm going to bet that you
    can't just mirror the existing drive (physical) without trashing it.

    BTW, you said they are SCSI in your other reply, but you state ATA in
    the controller above.

    So, is the 150 an ATA or SCSI?

    I'm guessing from the description that you did this with software RAID (ie,
    the RAID built into SBS). In which case, the answer is a simple no.

    No they are not. They are attached to CERC ATA. The CERC controller appears
    as a RAID device and basically 'pretends' to be a SCSI object but the ATA
    bit gives it away. Most ATA RAID does same.

    Grab 2*250GB ATA drives, RAID them, copy the install across. If you must.

    pretty sure I'm right that they are ATA but the OP is being confused as the
    controller appears as 'SCSI and RAID devices' in devman.

    I agree, the ATA in all the Cerc/Perc controllers means IDE and not SATA
    or SCIS, but the Device Manager always shows SCSI....

    Maybe he should run a BELARC report so that he knows exactly what is in
    the machine.
