    From SCSI to ATA

    Locked

    by deadrattie ·

    i have a client running:
    sbs 4.5
    exchange server 5.5

    regular sbs setup, with data files located on D: drive and exchange stores
    also located on the D: drive.

    well, seems when i tell them to clean up the d: drive and their
    inboxes/deleted items/sent items, no one seems to listen till the server dies with no space left on the d-drive.

    the drive is an old scsi 50 pin 8GB drive, which its time has come to put out to pasture.

    I’d like to throw in a 80GB ATA drive to replace it, and use norton ghost to mirror the old drive to the new drive.
    after the clone, if i disconnect the scsi drive cable from the old d-drive, setup the ATA drive as a slave, when i restart, will NT be a happy camper or am i looking for trouble.

    will nt see the drive and continue booting and will exchange server also be happy as if nothing ever happened. ?

    the c-drive is the only other drive in the sytem (its also scsi based) (cd rom is at drive F:)

    any thoughts or insight greatly appreciated.
    Thanks
    Peter

      up the points. The gurus usually don’t answer low point questions. Give it about 1000 points or more.

      side note: The Microsoft SBS newsgroup you posted this question in was for the Release Candidate 1 [beta]Small Business Server 2003 which is why you didn’t get anyone to respond.

        I’ve not heard of anyone mixing SCSI and IDE on their servers [except for the new Serial ATA drives using Promise 378/376].

        few things here. What mainboard are you using? How old is it? Particulars on the hardware would be helpful.

        Geez the 2940 Adaptec SCSI is 10mbps on a PCI bus and handles 7 devices. I would just say find some more SCSI HDD’s and install em. That was the neat thing about SCSI is the # of HDD devices you can string in the array.

        Note: Joseph Moore has a way of putting online a temp BDC, demoting the PDC, promoting the temp BDC, then taking off line the demoted PDC and doing what ya need to do. then reverse the process to get the refurbished server back online and back to PDC status. From what he says it works and he’s one of the gurus of NT/W2K servers. Side note: I seriously recommend you think about going to SBS 2000. There are migration tools and documentation widely available and it can be purchased for less than $1,000.00, comes with Exchange 2000, SQL 2000, ISA Server and is Active Directory based.

        That and getting away from the old SCSI and going to SCSI III or even SCSI II Ultra Wides…or even just opting for IDE and using Promise RAID mirroring or Stripe.

        Your dual PIII 900mhz processors, if they do the job, can still be used, but getting away from the ancient SCSI and going to something newer will benefit you in the long run.

        as TheChas said,you boot from SCSI, so adding in a IDE drive on the primary or secondary IDE channel, will make the BIOS see IDE and want to change drive letters on ya assigning the IDE HDD as C [because it’s an IDE based board]. That will cause havoc since your O/S is on the SCSI drive on the SCSI adapter. The BIOS will try to hand off C drive to the O/S as the boot so changing things around as per Sgt Shultz’s post will help with that.

      NT will not be happy after ghost from SCSI to ATA. has to do with boot record and boot.ini…i don’t know if the boot record will successfully point to boot.ini and even if it does, boot.ini will have to be modified as it has scsi/ide related settings…
      if you ghost your new drive, and it boots but hangs at a blinking curser, this is because boot.ini is not configured right…
      if it doesn’t boot at all, says no operating system or some such, that is because the boot record is not getting written to the right spot on the new drive…you can try ghost and then copy a good boot.ini file onto it…
      i think another way to do this is tape backup/restore…
      this is not going to be that easy unless you have disaster recovery type backup software that will let you backup the os ‘out from under itself’. if you don’t have that, you need to install your new hard disk as the boot disk, install NT on the new hard disk, configure it for your tape backup hardware, backup the hidden file boot.ini (at root level)use NT backup to backup your old boot disk. then you can boot from the old hard disk, use NT backup to restore the os to the new…etc etc. reinstalling is not that bad,

      For a data drive, I don’t believe that NT will have any problems with the ghosted drive.

      My big concern is NT drivers for the serial ATA card.

      Also, I am not sure that you can set a single hard drive as a slave. I know it does not work well for most standard IDE drives.

      Since you boot from a SCSI device, I also have a concern about how the motherboard will assign and recognize your resources.
      You may need to play with what slot you install the serial ATA card in so that the SCSI card is always first on the list.
      Otherwise, the motherboard may attempt to boot from the ATA drive, and may even assign the SCSI drive as D:

      I have to agree with DR, the easiest and safest method for what you need to accomplish is to install a new SCSI drive.
