I'm nervous. I have to replace a SCSI drive today that is in a dynamic disk set that is mirrored (see attached Disk Management attachment) in a Windows 2003 SBS server, and it's the boot disk of the set. The mirror is not broken, it is in a "Failed Sync" state, because of bad sectors on Disk 0.
I'm worried about making a mistake and this becoming a bigger, more time-consuming process than I want. I've read all kinds of horror stories and see all kinds of pitfalls. (see graphic "Device Manager" for SCSI information).
Of course I'm going to do a backup first. I'm planning on using Drive Snapshot, which I know can and will back up a dynamic disk.
In my research I picked up bits and pieces here and there, so this is how I plan to proceed, as a result. Please tell me if any of you see any flaws in this:
1. Do a backup. Verify backup.
2. Right-click on the two dynamic disk drive letters (C & E) and click "Remove Mirror" on the drive that has problems. I can't click on Disk0 itself, as that option is not available there (see graphic Can't Remove Mirror from... and Can Remove Mirror from...). This is worrisome, because I've read where others report that only one of the drive letters comes back and not both.
4. Remove SCSI Disk 0.
5. Move SCSI Disk 1 to same cable position as SCSI Disk 0 was.
5. Connect new drive (same exact model) to cable position where SCSI Disk 1 was.
6. Reboot the server. I'm worried about this step and the server not rebooting from Disk1, which was not the boot disk of the set.
7. Open Disk Management. 2. Right-click the mirror on the missing disk, and then click Remove Mirror. Will this be necessary since I already removed the mirror from Disk 0 in step 2, above?
8. Initialize the new drive so it has unallocated space.
9. Right-click the drive that was previously mirrored to "Add Mirror".
10.Choose the new drive as the drive to add to the mirror.
11.Hopefully the status will be "Resyncing"!
