Solutionnode CP03 should probably have a DECnet address of 17.13 instead of 17.11
You're running DECnet-OSI:
the easiest way to change the DECnet address is via editing SYS$MANAGER:NET$ROUTING_STARTUP.NCL and updating ROUTING PHASEIV ADDRESS = 17.13
Alternatively, you would need to run @SYS$MANAGER:NET$CONFIGURE and re-configure DECnet.
You need to reboot to make this change active.

Re: decnet problem
From your posted output, it would seem that nodes CP01 and CP03 are both trying to use network address 17.11. This is incorrect and will cause many problems.
For example, if you are on an Ethernet, both nodes will be attempting to use the same Ethernet MAC address (DECnet resets the MAC address of its adapters). This will cause problems.
You need to do follow the documented procedure for changing the DECnet node address of a node. It appears that you are using DECnet Phase IV. There are two steps that need to be performed:
- the SCSSYSTEMID value should be re-set in the MODPARAMS.DAT (the SCSSYSTEMID value is defined as (DECnet Area*1024)+(DECnet Node); see the HELP TEXT within SYSGEN for a longer description).
- reconfigure DECnet to use the new node address. This can be done using the NCP DEFINE EXECUTOR ADDRESS nn.nnn command.
You will then need to reboot the node that has the changed settings.

Re: decnet problem
My error, Volker is correct. You are running DECnet-OSI, not Phase IV.
My apologies.

Re: decnet problem
Identification = DECnet-OSI for OpenVMS
These nodes are using DECnet-OSI. As shown by the NCP output. Some NCP commands still work even when running DECnet-OSI.

Re: decnet problem
IF these nodes are in the same cluster AND you change the SCSSYSTEMID, you need to reboot the whole cluster.

Re: decnet problem
You need to set the address of each machine (node) to be a different value. You need to configure the naming database. You need to make sure that all machines are on the same LAN or have DECnet routing between the LANs, or are using "DECnet over IP".
To change the address you should use NET$CONFIGURE for Phase V (DECnet-Plus). You also need to ensure that the SCSSYSTEMID and SCSNODE system parameters match the DECnet address (area * 1024 + number) and DECnet local node nickname (6 characters long).
Good luck!
Cheers, Colin.
