SUMMARY
This article discusses FTSETUP--its features, how to use it, and how it works.



General Installation Issues
Before running FTSETUP, make sure that the drive becoming the mirror is &quot;raw,&quot; meaning that it is not formatted or partitioned. Also make sure that the partition(s) on the drive being mirrored do not take up all of the drive's capacity. For more information on requirements for fault tolerance, query on the following words in the Microsoft Knowledge Base:

EISA and HPFS and LADDR and FTBOOT.EXE

Running FTSETUP installs fault tolerance on a machine even if mirroring is not selected. If a machine cannot be made fault tolerant (if it has FAT drives or only one disk) FTSETUP presents an explicit warning; on machines that can possibly be made fault tolerant, the warning is still present, but is less explicit.

After fault tolerance has been installed and the machine has been rebooted, LAN Manager cannot be removed from the machine until fault tolerance is removed, even if mirroring is not active.

Current fault tolerance is not compatible with OS/2 version 2.0. Although it seems to install without problems, reboot reports CONFIG.SYS errors. As a result, LAN Manager can be removed from the machine without removing fault tolerance (as theoretically installed in FTSETUP) first.

Once you have scheduled fault tolerance for installation and exited FTSETUP, you cannot re-enter the program without rebooting. Attempting to do so results in the message &quot;DISKFT.SYS is in CONFIG.SYS but is not running. FTSETUP cannot continue.&quot;

Mirroring Issues
To determine the capacity available for mirroring/duplexing, choose  then  in FTSETUP.

FTSETUP allows you to select invalid actions (such as scheduling a drive for mirroring when no mirror is available or scheduling more capacity for mirroring than is available), but generates error messages when you choose the  button.

To schedule drives to be mirrored, use the Mirror Drives menu. When you finish scheduling and exit this menu no changes are noticeable. They do not become visible until you choose the Exit option in the FTSETUP Exit menu.

Once FTSETUP has made changes and you have been instructed to close all other processes and reboot, you cannot exit FTSETUP. Attempts to end it at the OS/2 task list or close it from the Desktop have no effect. You must reboot.

Other Issues
FTSETUP has an option for deleting drives as well. If you select Delete Drive and then select Remove Fault Tolerance, a warning states that you have &quot;...drives that are mirrored, drives pending mirroring or orphaned drives&quot; and displays the consequences of continuing. No mention is made of deleted drives. Choosing OK presents a message that says fault tolerance will change the partition configuration tables and that you must reboot. When you exit FTSETUP, the deleted drive is not available. Attempting to access it results in a SYS0108 message that the drive is being used by another process.

FTSETUP installs itself by inserting lines in CONFIG.SYS and a line in STARTUP.CMD that calls a command file that runs FTSETUP. When this file runs, FTSETUP presents messages about the progress of mirroring. When it is done, you must exit the program manually. Any commands in the STARTUP.CMD file following the call to run FTSETUP (such as NET START SERVER) are not executed until you exit FTSETUP. At some point in this process, the CALL FTAUTO in STARTUP.CMD is REMed out.
