Re: can't boot from mirrored boot drive

Well, I used bootcfg after I created the mirror and it looked fine. I've
just installed WinObj, but I can't seem to see anything there that helps me
identify what is the problem on this disk.

Basically, I'd like to know how to approch this disk. Do I break the
mirror, shutdown and remove the good boot disk rdisk(0) and just leave the
disk that doesn't want to boot in and boot to the recovery conole to check it
out?

Then if I can see the problem and take whatever steps, how do I put a mirror
back in place, without removing the mirror and putting the mirror back? I
haven't done this before... well, not in windows, only in PERC and other
hardware raid controllers and while I have googled this extensively, I get
conflicting information as to if I need a floppy boot disk with boot.ini on
it or not, which I don't currently have (I assume as the disks are mirrored,
they each have a copy of boot.ini right?)

Was there a step I missed in mirroring the disk, do I have to do anything
besides install it, go to disk manager and make it dynamic and then add
mirror to it? Do I have to make it bootable somehow first?

I've worked hardware RAIDs and even Linux S/W RAID without incident, but
this one has got me befuddled.

Thanks

The Recovery Console's bootcfg or map commands or using Sysinternal's
WinObj tool in the up and running installation may shed some light on
the situation.

Yes, I am... The first disk boots ok. There is an EISA partition that is the
first partition on the first rdisk(0). So I boot from the second. On the
second harddisk rdisk(1) there are only two partitions, the first is the
boot, but it will not boot.

Thanks for your response..

is that where the installation resides?

multi(0)disk(0)rdisk(0)partition(2)

Hi,

Recently, my mirrored drive in my 2K3 server died. I took the drive out,
removed the mirror, but new drive in, replaced the mirror. It says it is
healthing and the mirror is fine. However, if I try to boot from the
mirrored drive, it fails with the error:

windows could not start because the following file is missing or corrupt:
<windows root>\system32ntoskrnl.exe

please reinstall a copy of the above file.

Now that would normally say to me that the boot.ini is incorrect, but it
looks right to me:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows Server 2003 for Small
Business Server" /noexecute=optout /fastdetect

multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Boot Mirror C: - secondary
plex" /noexecute=optout /fastdetect

the disks are mirrored, so the path to windows should be correct yes? They
are sata drives, drive 0 and drive 1 on the main system board's controller.
I was able to format the drive correctly etc before I made the mirror> I can
look at properties of the disk in disk manager - everything seems sweet until
I try and boot the secondary. There are three partitions on rdisk(0) 102MB
EISA Configuration) C: 12GB NTFS (Healthy System) and Logs (G:) 62.40 GB NTFS
Healthy

rdisk(1) only has 2 partitions, the C: and G: which are mirrored and
healthy. When I set up the mirror, it did not give me the opportunity to
mirror the EISA Configuration.

Anyway, it would appear that I am running on empty to coin a phrase because
if my first drive fails, it looks as though I would not be able to boot the
mirror drive. How can I see what the state of that drive is? Do I need to
break the mirror and unplug the rdsk(0) and see if it will boot? What is the
best procedure for this.

Thanks
