This topic describes how to recover from a master console disk
failure.
Context
The hard disk drive in the master console is a mirrored pair to
protect against loss of the master console due to a disk failure. If one of
these mirrored pair of disk drives fails and needs to be replaced, perform
the following steps:
Steps
- Right-click the My Computer icon on your desktop and select Manage.
- Select Disk Management. The hard drives display in the right
panel.
- If the failing disk drive displays, right-click the main volume
of the drive and select Break Mirror.
- Shut down the master console and replace the failing disk drive
using the procedures detailed in the documentation for your master console.
Ensure that the new drive has its jumpers set the same as the drive that is
being replaced. The new drive must be the same capacity or larger than the
drive being replaced.
Note: - It might not be obvious which of the two drives has failed. In this case,
reboot with each drive connected in turn to isolate the failed drive.
- If the replacement drive has a boot record present, erase it prior to
use.
- If the master console fails to boot, due to not being able to find the
Boot Record, change the boot sequence in the BIOS to the other hard drive.
- Restart the master console.
- Right-click the My Computer icon on your desktop and select Manage.
- Select Disk Management. The hard drives display in the right
panel.
- If a disk drive displays in the list marked "Missing", remove it
by right-clicking the drive and selecting Remove Disk.
- If the new disk drive has a "no entry sign" displayed on it, right-click
it and select Write Signature. This removes the "no entry sign."
- Right-click the new disk drive and select Upgrade to Dynamic
Disk.
- Right-click the volume that you want to mirror and select Add
Mirror. This step starts the Add Mirror Wizard
- Use the dialogue boxes that display to configure the second volume.
- A dialogue box with reference to making changes to the boot.ini
file displays. You can safely ignore this.
- The status of both volumes, the existing drive and the new drive,
will change to "Regenerating" and will, after a short period of time, start
to show the percentage of regeneration completed. When the regeneration completes,
the status should show as "Healthy."
