SUMMARY:

Creating the boot floppy disks for the free Stand Alone Disaster Recovery utility, for an Intel machine.

DETAILS:

In order to create an Image using the free SADR Utility, the user must create UltraBac's SADR Floppies. These floppies do not need be made on the computer where the restore or backup will be performed. However, the hardware on the computer during the floppy creation needs to be compatible with the hardware at the time of backup and restore (e.g. complex RAID drivers.) The boot floppy disks may be created on a different (yet compatible) computer, but crucial files may end up being missing from the disks, and the floppies may be unable to boot up the original disk. If you are using a RAID controller, or have a tape device or SCSI device driver that was originally installed from floppy or CD, you need to make sure those drivers get installed on the floppy. (For more information, see UBQ000026 - Supporting Proprietary & Multiple Drivers with Stand Alone (Recovery) Floppies.)

BEI has created a batch file to automate the creation of the NT boot recovery floppies. From the Microsoft NT DOS Prompt, execute the batch file:

Figure 2: Format for the MKDISKS Command

This will explain the parameters that must be specified, as illustrated in the following example (Intel based):

Figure 3: Make Boot Recovery Disks

The parameters are explained as follows:

mkdisks cd_rom_path [tape_drive] [scsi_controller], and an example of the parameters are given: mkdisks f:\i386, where f: is the cd_rom drive, and \i386 is the location of the Windows NT (Server or Workstation) CD-ROM. (E.g. From the directory where mkdisks resides, type mkdisks f:\i386)

An example (assuming the system directory is: C:\winnt and the prompt defaults to the system directory, and the CD-ROM drive is f:

Go to the directory where the SADR utility is installed.
Now type: mkdisks f:\I386 and press return. Your screen will look like:

When you run the utility, you will get the following screens:

Following is a partial list of valid "tape_driver" parameter values and their associated type:

4mmdat	4mm DAT tapes
dlttape	DLT tapes
qic117	QIC floppy controller
qic157	QIC IDE controller
exabyte1	Exabyte SCSI-1 tape drives
exabyte2	Exabyte 8mm SCSI-2 tape drives
tandqic	Tandberg SCSI QIC drives
wangqic	Wangtec SCSI QIC drives
miniqic	Miscellaneous SCSI QIC drives

You can usually find your tape device by going into "Control Panels"/ "Devices" and searching for a device driver that "looks" like it would be a tape device driver and is "started". These devices usually stand out and are not difficult to find.

NOTE: With Intel based machines, the tape device driver argument is not necessary if not using a tape device for restore (e.g. When using a Static Mirror Image Disk rather than tape.) With Alpha based machines, when not using a tape device for restore, use "4mmdat" for the tape device driver.

The [scsi_controller] is optional and represents the filename of the SCSI_contoller driver. Supply this information only when the SCSI_controller driver is not supplied by Windows NT (Server or Workstation) CD-ROM. An example would be mkdisks f: 4mmdat ini910u.sys

You will need to have the following number of formatted floppies ready, and labeled (e.g. Stand Alone disk #1, Stand Alone disk #2, Stand Alone disk #3, Stand Alone disk #4, and Stand Alone disk #5):

Intel	3 floppies
Alpha (NT 3.51)	4 floppies
Alpha (NT 4.0)	5 floppies

NOTE: The tape device driver supplied above becomes NTTAPEDD.SYS and will be placed on floppy by the mkdisks process. If the following tape drivers exist in the <System Root>\system32\drivers directory, will also be placed on floppy, and will be automatically loaded during the recovery process: 4mmdat, exabyte2, exabyte1, miniqic, dlttape, qic117, qic157, tandqic, wangqic, and archqic drivers. The following SCSI device drivers, if they exist in <System Root>\system32\drivers, will also be placed on the third boot floppy disk: aha154x, aya174x, aic78xx, ultra14f, and ultra24f. All IDE device drivers are covered by the atapi.sys file.
