RE: HMC Connectivity Help

Oh, are these the port labeled S1 and S2?

Thanks!

There is a management port on Power 8's (and I believe earlier models) that is different than the standard ethernet. That, and our "standard ethernet" is fiber and the management is copper.
On our models there are two Management ports. And they are on the very bottom left back of the unit. Do not look in the card slot areas.

Thanks, Rob.

So just to be clear, you have one connection from your HMC to your network
and the IBM i servers are plugged into the same reachable VLAN? Do you
use the standard ethernet ports on the servers, or do you plug an ethernet
cable from the network switch to one of the HMC ports?

Thanks!

"Best" is in the eye of the beholder.

There are those who say it's ok for Payroll and other non critical stuff
to be on your open internal network but your FSP's should be on their own
private network. I suspect they know of some leak into FSP that I'm not
aware of or some such thing. In their school of thought your HMC would
utilize two NIC's. One would go to a separate subnet, vlan or physical
network to your FSP's and the other NIC would be for connecting to your
open internal network for remote HMC capability.

That being said, I just use one NIC in my HMC and put the FSP's (power
systems management port), HMC and my open internal network all together.
Just this week I had to get into my FSP's directly using ASM because of an
HMC issue (replacement mother card vs HMC password issue). So having to
go into the cones of silence room to get into ASM would be a bummer.
Especially after we move this to the offsite data center.

We also have redundant HMC's (thank God) which can control the machines in
each other's city in a pinch (like this week).
