To create a fault tolerance floppy disk for recovering from a failed bootmirror partition, you may need to correct the hardware identifier on the arc path name in the BOOT.INI file.
The following are the only two valid options to specify the arc name thatidentifies the disk/controller type:
Multi can indicate a non-SCSI disk drive supported by either the Atdisk.sysor Abiosdsk.sys driver, or a SCSI disk drive supported by a SCSI BIOS thatloads when the SCSI adapter detects a bootable device on the lowest SCSI IDon most SCSI adapters.
Intel (x86) computers running Windows use the Multi option as thedefault hardware identifier for the primary bootable disk drive.This is due to the SCSI BIOS, Atdisk.sys driver, or Abiosdsk.sys driversupport.
If the system is using a SCSI adapter and the primary boot drive of amirror set fails or becomes inaccessible and the SCSI adapter BIOS does notload, the Multi identifier option will fail to locate the healthy mirrordrive. As a result, the Boot.ini file on the Fault Tolerance floppy diskwill require the use of the SCSI option to boot the remaining mirror drive.
NOTE: The SCSI identifier option should only be used when the SCSI adapter BIOS is not loaded. Refer to the Concepts and Planning Guide, p.163 for ARC path variable specifications.
