IBM 5000 - Manual (Page 44)

Failover for Redundant Ethernet
Notes:
1. Only one controller in the redundant pair is active at any given time. For
example, if the primary Ethernet controller is active, then the secondary
Ethernet controller cannot be used for any other network operation.
2. Your operating system determines the maximum number of IBM Netfinity
10/100 Fault Tolerant Adapters that you can install in your Netfinity 5000
server. See the documentation that comes with the adapter for more
information.
The failover feature currently is supported by OS/2, Windows NT, and
IntraNetWare. The setup required for each operating system follows.
Configuring Failover on OS/2
1. Install the redundant NIC adapter according to the instructions provided with
the adapter and in “Installing or Removing Adapters” on page 50.
2. Use the ServerGuide CDs to install the AMD PCNet Ethernet Family adapter
device driver.
3. Using the MPTS utility program, select the driver from the list and select the
Edit button.
Note: Only one driver instance needs to be loaded for each redundant pair of
Ethernet controllers.
4. Change the PermaNet Server Feature keyword to TRUE and specify the
Primary and Standby slots that contain the redundant pair. Refer to “System
Board Illustration” on page 168 for the locations and slot numbers of the PCI
slots. The integrated controller is located in slot 9.
5. To enable the writing of messages to the IBMCOM\LANTRAN.LOG file when a
failover occurs:
a. Copy the file PCNETOS2.EXE from the OS2 directory of the diskette
created by the ServerGuide program to your hard disk drive.
b. Add the following statement to the CONFIG.SYS file:
Run=d:\path\PCNETOS2.EXE
where d and path are the drive and path to which you copied
PCNETOS2.EXE.
6. Restart the server.
The failover function is now enabled.
Configuring Failover on Windows NT
1. Install the redundant NIC adapter according to the instructions provided with
the adapter and in “Installing or Removing Adapters” on page 50.
2. Use the ServerGuide CDs to install the AMD PCNet Ethernet Family adapter
device driver.
3. From the NT desktop, select Control Panel, then select the Network icon, then
the Adapters tab.
4. Highlight one of the adapters that will be in the redundant pair and then select
the Properties... button.
