Set host not working

[byron moore]

I have always used the set host command to switch between nodes on our Cluster. Now that command seems to have stopped working and I get this error:

%SYSTEM-F-UNREACHABLE, remote node is not currently reachable

What do you learn from:

$ SHOW CLUSTER
$ MCR NCP SHOW KNOWN NODES
$ MCR NCP SHOW EXEC CHAR
$ MCR NCP SHOW KNOWN LINES
$ MCR NCP SHOW KNOWN CIRCUITS

Byron,

consider to issue the above commands on all nodes in your cluster, from or to which you cannot use SET HOST.

In addition to providing the above requests for details...

If you're on a managed network with managed switches and supported by a networking team (and that team is not "you"), then go have a chat with those nice networking folks. It's quite common for a managed network to get adjusted and to disable DECnet; there are various ways that communications with DECnet can be disrupted.

Good info. I will gather this info and get back to you shortly. Thanks for your answers.
