Example for Configuring LAN-FAILOVER on a NIC DE-602

[Vallentin, Manfred]

Hello,
i would configure a NIC (DE-602) for LAN-FAILOVER with OpenVMS 7.3.2.
Has anybody experience of this Tool "LAN-Failover" I need an example with steps for the configuring.

Thanks for your assistance.

Well, I'll assume a couple of things... Both ports are attached to the same LAN segment and they are both active.

If you want to do this while VMS is up and running, no network protocols can be running on the adapters, so stop TCPIP, DECnet, LAT, SCS, AMDS, etc.

The sequence would be:

$ MCR LANCP
LANCP> SET DEVICE/FAILOVER=(EIA,EIB)/ENABLE LLA0
LANCP> EXIT

Now you will have a device call LLA0 and you can reconfigure DECNet, TCPIP, etc to use that device.

To make these permanent and have it defined at boot time, change the SET to a DEFINE and the LLA0 device will be created early in the boot process. (Early enough that SCS will start on the LLA0 device, not the EIA0 and EIB0 devices.)

Hope that helps,

Dave Harrold.

There are some failover options with TCP/IP Services v.5.4 (which I assume you are running under v7.3-2 OpenVMS ?).

Check the link out below for and example of how to configure.
