Installing the NetWare SFT III 4.X MSL Driver on NetWare SFT III Servers
----------------------------------------------------------------------------
The \NOVELL\SFT3.4X subdirectory contains the following files:
README.TXT - This file.
DECMSL4X.MSL - NetWare SFT III 4.1X Mirrored-Server Link Driver
for both the DEC FDDIcontroller/EISA and the
DEC FDDIcontroller/PCI adapters.
Product Requirements:
Oper. Sys. - Novell NetWare SFT III 4.10 or 4.11

Section 1 INSTALLING THE NETWARE SFT III 4.X DRIVER ON NETWARE SFT III
-----------------------------------------------------------------------
The DECMSL4X.MSL driver will run only on Novell NetWare SFT III 4.10 and 4.11
server and takes advantage of the multiple MSL adapters feature of
NetWare SFT III 4.10 and 4.11. The DECMSL3X.MSL driver will run on Novell
NetWare SFT III 3.11, 4.10, and 4.11 but only supports a single MSL
adapter in an IOENGINE.
To install the NetWare SFT III 4.1x MSL driver on a NetWare 4.1x file
server, perform the following steps (Note: DEC FDDIcontroller refers
to either the EISA or PCI variants):
I. Verify that the FDDI network interface card (NIC) is properly
configured and installed. Refer to "DEC FDDIcontroller/EISA
Installation" or "DEC FDDIcontroller/PCI User Information"
for instructions.
II. Perform substeps IIA. and IIB. to configure the NetWare 4.10 file
server to use the DEC FDDIcontroller NetWare SFT III 4.1x MSL
server driver.
A. Copy the driver files to the server hard disk in the same directory
from which MSERVER.EXE is started.
For example, if MSERVER.EXE was located in C:\NETWARE, you would
enter the following command to copy the driver:
COPY A:\NOVELL\SFT3.4X\DECMSL4X.MSL C:\NETWARE
B. Edit the IOSTART.NCF file to automatically load the new MSL driver
every time the server is brought up:
LOAD C:DECMSL4X.MSL SLOT=48
NOTE
The "slot" value given above is an example. For the DEC
FDDIcontroller/EISA the slot number will in the range 1-15 and
is the EISA slot where the DEC FDDIcontroller/EISA is installed.
For the DEC FDDIcontroller/PCI the number will be a value greater
than 16 and represents a unique identifier for the DEC
FDDIcontroller/PCI adapter found.
Replace "C:" with another directory path if the MSL driver was
not copied to the same directory as MSERVER.EXE.
III. Start the server with the DEC FDDIcontroller MSL server driver.
Enter the following command at the DOS prompt:
MSERVER
The changes made to IOSTART.NCF in step II above take effect.
Section 2 ADDITIONAL MODES OF OPERATION
----------------------------------------
NETWORK COEXISTENCE MODE
------------------------
In a "Normal Mode" of operation, the MSL link will be a point to point
connection between the two MSL cards. The DEC FDDIcontroller also
allows the link to coexist on an FDDI network as long as there are
NO ROUTERS in the path between the two linked servers. In this mode of
operation IT IS MANDATORY THAT YOU SPECIFY THE PARTNER'S IOENGINE NAME.
To do this, keep both MSL adapters connected to the network and load
the MSL driver on both IOENGINEs. From the example in Section II:
LOAD C:DECMSL4X.MSL SLOT=48 PARTNER=IO_RIGHT
Where IO_RIGHT is the name of the other server's IOENGINE.
Repeat this on the other IOENGINE using this IOENGINE's name.
The IOENGINEs should find each other, reporting that the link is
available and will synchronize once the server is activated.
INCREASING MESSAGE RETRY COUNT
------------------------------
Running the driver on a busy network increases the possibility for a packet
to become lost between the two MSL cards. If your network is fairly loaded,
it may become necessary to increase the retry count. To adjust the retry
count, add the following switch to the command line when loading the
MSL driver.
LOAD C:DECMSL4X.MSL SLOT=48 PARTNER=IO_RIGHT RETRY=2
FULL DUPLEX OPERATION
---------------------
The driver can be configured to run in a Digital proprietary mode of
operation known as Full Duplex (FDX). The MSL adapters must be connected
in a point to point configuration. In this mode, the normal FDDI token
rotation is eliminated, allowing the adapters to send and receive at the
same time. This increases the bandwidth of the connection above the
100 Megabits/second limitation of standard FDDI. To activate this mode of
operation, add the following switch to the command line when loading the
MSL driver.
LOAD C:DECMSL4X.MSL SLOT=48 FULLDUPLEX=ON
