Tony,
Assuming you really described all the picture (*) it may be an issue
with network rules based on MAC address - that's the only "network
thing" you have changed with HMC replacement.
(*) it is not honest/dishonest, it is about trust. I trust NO ONE, when
analysing IT problems. No one, including me. Nobody's perfect, it is
possible to miss some detail. :-)

Thanks for your reply.
We do appear to have a "network" issue. It is strange because we copied
the configs from the old machine are moved the cables from the old HMC to the new HMC.
One interface work for remote access to the remote HMC. One the other interface, I can
ping the remote gateway and the local HMC, but I cannot ping the SEs at the local site so
the manual installation does not work.
We certainly could (add do) use the remote access to the local HMC. We
want to get the remote HMC working for our DR test.
Thanks again.
Tony

Well, as far as I understood you have a problem with connectivity.
1. Check network connectivity, internal firewalls, rules, etc.
2. Use "manual object installation" - remote HMC will NOT discover your CPCs.
You have to define it manually, it is not hard.
3. Domain security. Leave default or check it thoroughly.
BTW: What do you need actually?
I'm asking, because you wrote about remote HMC, but usually users need remote
access to (local) HMC. I did use both and I have to admit the functionality
available with remote HMC *but not with remote access* to the local HMC is
rather rare. In other words: vast majority of features is available though
remote access.
Last, but not least: remote access to local HMC is much easier to set up.

Hi List,
I have a new DR machine (BC15) that we have installed in Austin. The
machine is running and we tested out a DR scenario when we were there. At that
time , we did NOT have our remote HMC installed. A few week later we are now
installing our remote HMC and we are having an issue. The HMC do not seem to
talk to each other.
We have used the same cables and copied the configurations from the
previous machines. Our remote HMC (Oaks, PA) cannot ping the SEs in Austin,
however the eth1 interface is up and running.
Has anyone run into this situation??
Can you suggest any potential solutions??
Thanks in advance
Tony
