If the partition containing the Windows NT Server system files is mirrored and then lost, you can use a fault tolerant boot floppy disk to restart Windows NT Server and access the mirror of the lost drive. This article explains how.
A fault tolerant boot floppy contains the files necessary to boot Windows NT from a mirrored partition. For instructions on creating a fault- tolerant boot floppy for x86-based systems and RISC-based systems, see the Concepts and Planning Guide for your version of Windows NT Server.
Once Windows NT is successfully booted from the fault tolerant boot floppy, the files and directories on the mirror drive are available for normal disk operations. Even if the disk containing the primary partition is lost, no differences are apparent to you (unless you study the status information displayed in Disk Administrator). But fault tolerance no longer exists: if the remaining partition is lost, all its data is lost also. So it is safer to break the current mirror set, configure a new boot and system partition, and create a new mirror.
Alternate Method of Creating a Fault Tolerant Boot FloppyIf the primary partition of a mirror set is lost, you cannot start Windows NT Advanced Server, and no other Windows NT system is available from which to create a fault tolerant boot floppy, follow these steps:
