Re: Can't reach HMC console remotely

We have 3 HMC's here. One is at another building across town and two are in this data center. One HMC is dedicated to our iSeries machines and the
other HMC is dedicated to the pSeries machines. The two pSeries HMC's share a routed private vlan and can see everything, both for redundancy sake.
All of the HMC's have a private lan for the HMC to system connection and the other port is connected to our internal network so that we can do the web
based HMC management thing.

I think you may want to just purchase a small switch and plug all of your HMC connections into that private little switch and let the servers talk to
the HMC to their hearts content. That way, you get your DHCP connectivity and your network guy stops flipping out.

Good luck,

That's one possible configuration. We only have one cable coming out of
our hmc and we can ping it, and our FSP from our network.

Can't say when I'll get to this. I'm also a little suspicious of our
network configuration. The network guy keeps telling me that the HMC
Console can NOT be allowed to be a DHCP server, but the IBM docs tell me

it

must be. I'm trying to figure out how to tell the boss there's another

HMC

upgrade but I can't guarantee that will allow me remote access either.

If YOU find an answer before hearing from ME, I'd appreciate a heads up

as

well.

Thanks.

Hello Thomas,

I seem to be in the same boat as you. I recently upgraded the HMC to
v6r1.3 myself and cannot connect to the HMC over VPN. Its too slow and

just

times out. At least, that is what I think. I can connect to the console

work

station, but again, it is soooooooo slow. Worse than dial up.

I'd like to hear if you find a solution. And upgrading to version 7

right

now is not an option.

Thank you,

Sorry I'm a little late on this thread and if I repeat things already
said... If this is the ONLY HMC and it's in the same rack as the
system... then it shouldn't be a problem. The connection between the HMC
and the system should be just 1 cable from the HMC (eth0) to the HMC1
port on the system. That is the entire network where the DHCP server
will be used. The System FSP will get its IP address via DHCP from the
HMC. No other machines shuld even be able to see the DHCP server. There
will be a second cable from the HMC (eth1) to your corporate network
where you will most likely have assigned a Static IP that is correct for
that network.
