Set host not working

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

$ show system/proc=net*

Re: Set host not working


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

Re: Set host not working

Byron,

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

Re: Set host not working

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.
