Creating a mirror on a Windows 2000 server

Posted on 2006-03-21
Last Modified: 2010-04-13

I have a mirrored hard drive that recently crashed.  The OS is Win 2000 Server.  The hard drives are IDE.  The drive that crashed was the primary 0.  I moved the good primary 1 to the primary 0 spot and installed the new drive as primary 1.  I am not sure what to do to correctly setup a new mirror.  Need some help.  Hope I wasn't too vague in my description.

    did you use windows mirroring or hardware RAID?

    if windows mirroring make sure the disk turns up in disk management and we will go from there

    We need to re-establish the mirror.  Using ghost/clone software will merely create a copy of the disk at the time which will again go out of date the when he next uses the system.  Re-establishing the mirror will ensure both disks are constantly.....well mirrored :)

    Im imagining that your using some kind of hardware RAID as Windows won't let you boot off a Dymanic disk which is what the disk needs to be for Windows to be able to RAID it.  That being the case then there will be documentation on how to re-establish the mirror with the RAID controller or motherboard if it's onboard RAID.

    Sorry about not giving all the details needed, I'm not too experienced with server hardware and setup.  I believe that it was just a software mirror.  How do I determine this?  Does a hardware mirror require SCSI drives and a RAID controller??

    1. What I see now in Disk management on the left side of the window is Disk 0, Dynamic, 57.27 GB Online.  To the right of that I see OS (C:) 29.29 GB NTFS Failed Redundancy (System).  To the right of that I see Data (D:) 26.57 GB NTFS Failed Redundancy.  Both with the "mirrored stripe" above them.

    2. Below that on the left I see Disk 1 Dynamic 128.00 GB Online.  To the right of that I see 128.00 GB Unallocated.  The "unallocated" stripe above it.

    3. Below that on the left I see Missing Dynamic 55.87 GB Offline.  To the right of that I see OS (C:) 29.29 GB NTFS Failed Redundancy (System).  To the right of that I see Data (D:) 26.57 GB NTFS Failed Redundancy.  Both with the "mirrored stripe" above them.

    Hope this clears things up.  I would like to just use disk management to re-establish the mirror if possible.

    Ok,  i started right clicking on the drives in disk management and selected "remove mirror".  Then I chose the create mirror option and it is regenerating now.
    Not sure who to give the points to, but thanks to everyone for the response.

    thats correct mate, when windows mirror fails you have to break it and then rebuild - you already figured that out though :)

    thats not always the case my friend, windows will indeed allow you to boot off dynamic disks, there is very rarely an issue in regards to the boot.ini file but i have around 100 servers that i know of running dynamic disks and even when the mirror fails, i can boot off the secondary     -  just a useful note
