(Windows 2003 R2 software Raid mirror 2x SATA HDD 160GB) I have a problem. I removed
a faulty mirrored Dynamic drive in software thinking I didn't need a "missing Disk
0 failed redundancy HDD".
It wasn't avaliable in "system manager" so OK it's a DUD hdd..... I removed it
by taking it out of the Disk management and was going to modify the "Boot.ini". (See
Below) before rebooting the server.
***************************************************
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003, Standard" /noexecute=optout
/fastdetect
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Boot Mirror C: - secondary plex"
************************************************************************
What I need to know for editing the "Boot.ini" is.... Can I just delete the bottom
line???
Do I need to change the rdisk(0) to rdisk(1) if the "Disk management" (in Computer
management) says at the moment the working drive is labeled as Disk 1 or will it
change after I reboot and become 0 so rdisk(0) is OK??
Also "AFTER" I had removed the drive in Disk management I read a Microsoft white
paper that has warned not to break the mirror and remove the copy of the drive (See
below below). What should I do???
Thanks!!

Missing dynamic disks
If Disk Management shows a missing dynamic disk, this means that a dynamic disk that
was attached to the system cannot be located. Because every dynamic disk in the system
knows about every other dynamic disk, this "missing" disk is shown in Disk Management.
Do not delete the missing disk's volumes or select the Remove Disk option in Disk
Management unless you intentionally removed the physical disk from the system and
you do not intend to ever reattach it. This is important because after you delete
the disk and volume records from the remaining dynamic disk's LDM database, you may
not be able to import the missing disk and bring it back online on the same system
after you reattach it.
Text-mode setup and Recovery Console
Never delete or create a partition on a dynamic disk during Windows 2000, Windows
XP, or Windows Server 2003 text-mode Setup or when you start the computer by using
the Recovery Console. If you do so, permanent data loss may occur. For more information
about this issue, click the following article number to view the article in the Microsoft
Knowledge Base:
236086 (http://support.microsoft.com/kb/236086/ ) System or boot disk listed as
Dynamic Unreadable in Disk Management
The mirrored drive
Never break a healthy system disk or boot dynamic mirrored volume and expect the
mirrored drive to replace the original primary drive if it fails. The manually broken
mirrored drive is assigned the next available drive letter, and this is updated to
the permanent record in the LDM database. This means that regardless of what position
that drive takes in the boot process, it is assigned the new (and incorrect) drive
letter, so the operating system cannot function correctly.
Note Windows software mirroring is a fault-tolerant solution that makes sure you
can maintain access to data if you have a hardware disk failure. Software mirroring
is not intended to be used as an offline backup mechanism.
