SYMPTOMS
When you attempt to use a system disk to boot from a mirror of the Windows NT Advanced Server boot partition (as described in the Windows NT Advanced Server "Concepts and Planning Guide"), the following STOP message appears:
CAUSE
This STOP message appears when the system is not given enough time to fully replicate the primary partition to the mirror partition before the system was shut down and restarted with the system disk.
RESOLUTION
To avoid this problem, make sure FTDISK.SYS has completed mirroring from the boot partition to the mirror partition. You can confirm this by selecting the mirror in Disk Administrator. The lower-left corner of the Disk Administrator window is a status bar; it should say:
- "Mirror #x: [REGENERATING]" if the system has not finished mirroring the partitions.
-or-
- "Mirror #x: [HEALTHY]" if the mirror is ready to be booted from.
MORE INFORMATION
To mirror a partition in Windows NT Advanced Server:
(In this example, these steps mirror the boot partition.)
- In the Disk Administrator window, select the boot partition.
- Press the CTRL key and select free space on another physical drive that is equal or greater in size.
- From the Fault Tolerance menu, select Establish Mirror.
- Quit Disk Administrator, and then shut down the computer.
When you restart Windows NT Advanced Server, FTDISK.SYS begins mirroring the information from the boot partition to the mirror partition.
