TCPIP issues on an Alpha ES45 running OPVM V7.3-2

I'm having an issue with stopping and starting TCPIP. I've never experienced this before.

The main reason for this is because I have three nodes in a cluster, the first and second nodes are on the same vlan 10.1.1.nn while the third node is on a different vlan 10.128.8.nn.

The tcpip$configuration logical is pointing to a common file. When I configured TCPIP (tcpip$config) on the third node, the gateway changed for all three nodes. (I.e. the first node ip: 10.1.1.12 using the 10.1.1.1 gateway, the second node ip; 10.1.1.10 using the 10.1.1.1 gateway.) The third node ip is 10.128.8.26 using the 10.128.8.101 gateway.

This caused an issue when the cluster was rebooted. I attempted to redefine the tcpip$configuration logical on the third node and reconfigured tcpip but each time a reconfigured the gateway it would change on the first and second nodes. I've even attempted a reboot of the third node but to no avail same issue.

Ronald,

the default route information seems to be stored in the file pointed to by the TCPIP$ROUTE system logical and would typically be SYS$COMMON:[SYSEXE]TCPIP$ROUTE.DAT;1

On a common system disk, this file would be used by all nodes in the cluster booting from that disk. And changing the default gateway on one of the nodes will also change it on the other nodes, as there is only ONE file to store this information.

You may get around this problem by putting a TCPIP$ROUTE.DAT file into the specific directory of the 3rd node and defining a TCPIP$ROUTE logical - before starting TCPIP - to point to that file on that node.

We have 1 file and put all default routes in it (by commands, not the menu). At startup tcpip picks up the correct version (by trying them all and rejecting the ones not working ?).

Thank you all for your help in this matter. This has fixed my issue. I just created a copy of the TCPIP$CONFIGURATION.DAT and TCPIP$ROUTE.DAT to the third node SYS$SPECIFIC:[SYSMGR] and re-defined the assoicated TCPIP logicals.

Thank you for all your help,
