General Installation Issues
Before running FTSETUP, make sure that the drive becoming the mirror
is "raw," 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 "DISKFT.SYS is in CONFIG.SYS but is
not running. FTSETUP cannot continue."
Mirroring Issues
To determine the capacity available for mirroring/duplexing, choose
<Config> then <View Drive Status> 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 <OK> 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 "...drives that are mirrored, drives pending mirroring or orphaned
drives" 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.
