Configuring for failover: The failover feature currently is supported by OS/2™, Windows NT Server, and IntraNetWare. The setup required for each operating system follows. IBM Operating System/2 (OS/2): Note: The OS/2 operating system does not support hot-plug operations. 1. Add the redundant NIC adapter according to the instructions that are provided with the adapter. 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.The integrated controller is located in slot 2 (PCI bus A slot 2). 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 root directory of the diskette that is created using the ServerGuide CDs 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. Windows NT Server: IBM offers hot-plug support for Windows NT Server Version 4.0. Failover can work in conjunction with hot-plug support or independently. If you are not using hot-plug support, go to "Windows NT Server failover setup" on page 71.
