MP of a rx2620 logging into another 2620

We just installed 2 rx2620's.
I configured the individual MP's with the following name and addresses.

wrlovt11 - 10.154.254.42
wrlovt12 - 10.154.254.43

So, when I hop to the console on the MP of wrlovt11, it takes me to wrlovt12.

When I log into the console on the MP of wrlovt12, it takes me to wrlovt12.

Any thoughts on how this might be happening? I have checked with our networking guy, and everything is cabled and configured correctly on our switch.

Re: MP of a rx2620 logging into another 2620

The issue sounds to be with MP lan network configuration.

Are you using DNS? Have you disabled DHCP since you are using static addressing?

What you see in MP > CM > LC on both the server?

The proper connection ( to correct MP in this case ) requires correct IP to MAC address ( sticked on the server ) binding. Check using "ping" & "arp" commands.

MP reset or power cycle/off of server wrlovt12 could be tried out to isolate the problem.

S-un B-ix-S,

If I am understanding you correctly, doing the commands "telnet wrlovt11" and "telnet wrlovt12" both connect you to the same system, the one at 10.154.254.43.

My first suggestion is to telnet explicitly to the address. If that succeeds, it is a DNS problem (or stale DNS data on the machine that you are using to originate the telnet connection from).

If the numeric address telnet still has the problem, I would be suspicious of other network configuration, but without the details of your configuration, it is hard to guess.

DHCP has been disabled, and we are not using DNS.

I will try doing a hard reset of the MP here momentarily.

I have powercycled the server and it does not seem to have affect on it.

Bob,

I should have been more clear. On the mp command menu...

it gives the option to go to console...

when i type CO...

the mp of wrlovt11 goes to the console of wrlovt12.

Re: MP of a rx2620 logging into another 2620

S-un-B-ix-S,

if you do perform the COnsole command
what do you then use to be 100% sure you identify your related host(s) ?

What OS is this ? If Windows, then you get the SAC prompt and the 'i' command will give the IP address of the host.

Since you are not using DNS, you always telnet with the ip address, right or do you have hosts files forname resolution also ?

Can you ping both MP's succesfully using their IP address and using their hostname ?

How about if you reconfigure one of the MP's with another IP and hostname just for a test ...

S-un B-ix-S,

That is not possible. It is more probable that the ssytem disks were cloned and the system name was never changed.

Try creating a file on the system disk of each system and see if it is visible from the other system.

If I am correct, you are not likely sharing a disk. If you are sharing a disk, you may have booted both systems off of the same disk. If you are running an OpenVMS cluster on a shared system disk, this is ok (provided you have two different system roots on the disk), otherwise, this may very well be a bad idea.

S-un-B-ix-S,

Also note, the IP address of the MP is totally (I mean TOTALLY) independent of the IP address of the actual system. They are using different LAN adapters.
