Thanks for the info, Rob.
Two of the systems (Primary and Dev) are in the same rack. The DR machine is in a different building, but all three machines are on the same VLAN.

Yes, you can manage all three with one HMC. However if they are geographically dispersed you may get some strange discussion from IBM regarding that. We have two HMC's for this reason but I often manage the other site with the local HMC. CE's are getting educated and are quite content accessing the HMC's remotely. (Especially if you put the keyboard on the floor in the rack just to make it ergonomically vicious.)
People like Jim and Larry really like to have their HMC's and FSP's on a private VLAN. Or better yet a physically different LAN. I find that physically different LAN hard to do when the machines are geographically dispersed. And I fail to understand why it's ok to have trivial stuff like payroll and whatnot on the same vlan as all your users but it's curtains for the free world if the FSP's and HMC's are not separated off.
The way it's been explained to me is that they find hacking into the FSP pretty easy to do. Maybe because a bulk of accounts use defaults or some such thing.
Note: HMC's have multiple ports. In Jim and Larry's world they use one port for you to access the HMC remotely and the other port to put the FSP on so it's on a separate network.

Sent by: "MIDRANGE-L" <midrange-l-bounces@xxxxxxxxxxxx>
Good morning all,
While I was at last weeks' conference, I discovered the advantages to
installing an HMC for system management. I am looking at purchasing an
HMC (model 7042-CR6) to use on these three machines:
* 8202-E4D (Primary)
* 8202-E4B (DR)
* 8286-41A (Development)
All have v7r1 on them with the latest PTFs and all machines have a single
LPAR on them.
Right now we currently use OpsCon to access the console when we are
loading PTFs, etc. on them. My primary question is - will this HMC work
with all three machines, and if so, how much work is it to install it so
that I can manage all three machines with it? Will I have any problems
moving from OpsCon to the HMC? As it stands right now, each machine has a
specific network port with a dedicated IP address so we can access the
console from a terminal.
Thankee-sai!
