  • Recovering a failed disk in a software raid mirror

    Does anyone know if there is a documented way to properly replace a failed physical disk that is a member of a software RAID 1.

    Parameters:
    Windows Server 2003
    RAID 1
    Failed disk is disk 0

    Everytime I have had to deal with this the server will not boot when you put in the new disk. I am looking for the proper way of doing this. The only way that has worked for me is to make a bootable floppy putting ntldr, ntdetect.com, and boot.ini onto a floppy and modifying the boot.ini to map to disk 1. Once in the OS then I recreate the mirror and resynch onto disk 0 but the results have been mixed.

    I just would be interested to know if there is another way of doing this and if Microsoft has ever documented such a procedure?????

    Thanks to anyone that can shed some light on this matter....

    and more to your query:

    I really dislike dynamic disks and software RAID1 is, IMHO, substandard. Get a decent RAID card and do it in HW. Total cost of ownership will be lower.

      That second KB article is exactly what I was looking for.

      I totally agree with the whole hardware RAID thing. Unfortunately, I work as a tech support analyst for a rather large computer manufacturer and I have to support customer's that have implemented software RAID.

      I really appreciate your prompt reply on this too.

      Have a good one.

        Instead of changing to boot.ini, I used to change the Primary drive in the BIOS (assuming you have that option). Saved a bit of dicking around.
        1 1 was a racehorse.
        2 2 was 1 2.
        1 1 1 1 race 1 day,
        2 2 1 1 2
