Considerations when combining failover and hot-plug
functions:
If your operating system supports hot-plug
PCI adapters and the optional redundant NIC adapter is
installed in a hot-plug PCI slot, you can replace the NIC
adapter without powering off the server — even if it is the
primary Ethernet controller. Disconnecting the Ethernet
cable from the primary Ethernet controller will cause the
Ethernet traffic to switch automatically to the secondary
Ethernet controller. This can be very useful if a faulty
adapter causes a network problem, or if you want to
upgrade the primary adapter hardware.
Note: If you hot replace the primary adapter while the
Ethernet traffic is being handled by the secondary
Ethernet controller, the traffic does not automatically
switch back to the primary adapter when the
primary adapter comes back online. See below
“Configuring for failover”.
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):
1. Add the redundant NIC adapter according to the
instructions that are provided with the adapter.
Note: The OS/2 operating system does not support
hot-plug operations.
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
