OS/2
The OS/2 device driver and associated files reside in the
A:\LANSRVR subdirectory.
The OS/2 device driver can handle up to 4 ethernet controllers.
These controllers can be configured as any combination of individual
networks or redundant pairs.
A redundant pair of network adapters can be defined such that a loss
of good link status on the primary adapter will cause all ethernet
traffic on this link to be automatically switched to the standby
adapter. If the link for the primary adapter is restored, the
sessions on the standby adapter will automatically switch back to the
primary adapter.
To enable failover operation, run the MPTS program and edit the AMD
device driver parameters. Set the PermaNet Server feature to TRUE.
Note that this parameter is case sensitive and must be entered in
upper case. Enter the parameters for the Primary and Standby slots.
The slot number for the onboard adapter is E. To have a message
written into IBMCOM\LANTRAN.LOG whenever a failover occurs, copy the
file PCNETOS2.EXE onto the hard disk and edit the CONFIG.SYS file.
Add the statement:
RUN=c:\path\PCNETOS2.EXE
to the beginning of the file, where c is the hard disk and path is the
directory path that you copied the PCNETOS2.EXE file into.
Once the machine is rebooted with the PCNETOS2.EXE statement
active, PCNETOS2.EXE will be active and cannot be overwritten.
To update the PCNETOS2.EXE file in the future, the user must first
remove the above statement from the CONFIG.SYS file and reboot the
machine.
