Failed controller C gone but data and Exchange on D still intact

    I got called in to client who has had a RAID Controller failure.
    Adaptec 29320-AR
    Tried in a new Server with another pair of drives...

    Having replaced the Controller - the ARRAY is NOT detected
    So his C drive is toast!

    This is a DIY job with External USB drive (single!) as Backup which was
    DROPPED 3 days before
    and the IT guy decided to get it mail order. Drive arrived same day as Raid
    failure.

    Originaly this was 2 x 36Gb as RAID 1 for Windows
    and 2 x 36Gb RAID 1 for Exchange and Data

    When they ran out of space the IT guy shutdown exchange and added a 200Gb
    SATA RAID
    and removed the old 36Gb DATA RAID this contains Exchange and All user
    data....
    Luckily this is still intact!

    My question is can the Exchange Databases on the D drive be used to recover
    data??
    Are there any procedures was this kind of recovery??

  2. Well, that's not really surprising ....this can happen. :-(
    Wow. They need more than one drive....these should be swapped out daily and
    stored offsite.
    Possibly, but you'll need to explain what you've done - you may be able to
    do a DR restore and overwrite the databases ,or you may need third party
    tools such as Quest Recovery Manager.
    Try posting with more detail - e.g.,

    What's the state of the server now?
    Have you done a new installation of SBS?
    Was there any documentation about the previous install?
    Do you know the exact path of the databases/logs?
    Has the server been reinstalled as identically as possible to the previous
    incarnation - meaning, name, domain name (NetBIOS name & DNS), etc.)?

  3. Hi Simon:

    In addition, you may want to look at the recovery software from:

    http://www.runtime.org/

    in similar circumstances there "getback" software allowed me to recover from
    a failed RAID1. Adaptec, without specifically recommending them did suggest
    them.

    You should speak with their support before doing anything, but if you
    already think the drive(s) is/are toast, you can't really lose anything.

    Provided one of the drive from each array is readable and you can swallow
    the cost, try using Acronis True image server with universal restore, I may
    be crap at servers but recovery is something i do know a bit more, so this
    may work for you. (chances of both drives died on a RAID-1 the same time is
    very low)

    Find a spare machine, with a IDE or SATA drive big enough to hold both the C
    and D, install Windows server on this, install TIS with UR, partition the
    drive to about same size as what you had before (ie. 33GB/33GB), get an
    external driver ready, ideally Firewire with a Firewire card as TIS doesnt
    always work great with onboard USB2 controllers.
    Install the Adaptec card, make sure Windows drivers installed, plug in one
    of the SCSI drive from the OS RAID-1, start up Windows, make sure BIOS set
    to boot from the IDE/SATA drive.

    Once Windows started ok, start up TIS, and choose to create an image of the
    SCSI drive, choose to image the whole drive inc MBR, rather than just the C:
    , image this as a file onto the firewire external drive.
    Once done, turn off and swap the SCSI drive with the one with Exchange on
    it, do the same as above, so by the end, you should have 2 files, each file
    holding the content of the whole drive.

    Next step is using TIS to create a bootable CD, to include UR options.
    Then download the 29320-AR drivers and put them onto a floppy.

    Now plug the SCSI card back into the original server, plug in the drives,
    create the RAID-1 sets again, so you should have 2 RAID-1 drives with one
    bootable, IMPORTANT !!, if you are not 100% sure, get 4 new SCSI drives to
    play with so you always has the original when things go wrong.

    Onec your drives are setup as RAID-1 and ready to go. put in the bootable
    CD, plug in the firewire drive, start the PC (make sure CD is first bootable
    device) , onec TIS start, choose RECOVERY, point to the external drive and
    find the image for the OS, it should ask if you wish to include some
    drivers, point it to the floppy drive so it can slip the 29320-AR drivers
    when restoring. The rest is just common sense answers.
    Once you done this, restart the PC with the Acronis CD still inside (do NOT
    allow it to boot to Windows as your Exchange is missing), now do the same
    but point to the file holding your Exchange, restore this to the second
    RAID-1 set, as its not a OS image, it wont ask if you want to use Universal
    Restore.

    Once restored, remove the CD, restart making sure the RAID-1 holding the OS
    is the first bootable device, with a bit of luck, you should have a fully
    functional OS and Exchange as before, may need to reinstall some drivers and
    replace the LAN details.

    -------------------------------------------------------------------------------

    Another way I use is with PowerControl, after you extracted the EDB from the
    damaged drive, on a new Exchaneg server, install the software and then it
    allows you to read the EDB directly and put the emails into individual
    boxes.
    But if you can get the first method to work, it will be easier and quicker,
    as PowerControl is not cheap either.

    If you need more info, please feel free to ask
