Re: vHMC web/network access WAS: vHMC desktop size

Now go back to the iACS main stuff. Right under Welcome make sure your

Pete,
I went to our VMcenter. From there I launched a remote console session to
our vHMC.
Console Management, Console settings, Change Network Settings, LAN
Adapters tab. I have four entries
Eth0 ... 0.0.0.0
Eth1 ... 192.xxx.xxx.1
Eth2 ... 192.xxx.xxx.24
Eth3 ... 10.10.6.97
We do not use the 192 settings. Those are probably there from initial
setup. Our Power systems are in the 10. network.
Check your Name Services tab and see that you have DNS setup. We have
both boxes checked and four DNS entries. We also have two suffix search
orders entered. We may be transitioning domains.
Now click on Test Network connectivity. Enter in your PC name, with the
domain name (if you do not have that domain in the search list). In my
case I had to enter GDL83.dekko-1. Did I mention we are transitioning
domains?

Now on your PC try this:
Nslookup 10.10.6.97
This should return your hmc name. If it doesn't slap yourself silly
(since you're the network guy) until you go fix your DNS and enter your HMC
in there.
Now you should be able to get to https://hmcussi.corp.dekko.com

Now open iACS. Not an emulator session! But the full enchilada with the
General, Database, Console and Management sections. Under Management,
System Configurations. Find your system in there and click Edit. Under
the console tab select HMC, then enter in your host name / ip address for
your hmc. I use names and not IP addresses. Our network guy has studied
under Catbert and loves to play games with us by renumbering stuff on a
periodic basis. If you click the Verify Connection tab you will see that
it uses ports 2300 and 2301.
Now go back to the iACS main stuff. Right under Welcome make sure your
system name is there. Under Console select 5250 console. There's your
system console session. "Hardware Management Interface 1" is your ASM or
Advanced Systems Management. There are those who feel that it's ok to have
your payroll data, engineering drawings, missile launch codes, etc on your
corporate network but heaven forbid you should put your ASM or HMC
interfaces to your power systems on your corporate network. I fail to
understand that.

Normally the only time I use Vcenter to get to the vHMC is for upgrades
and to start the shared system console sessions.

Patrik,

*I* am the "network guys" you refer to. I didn't realize that the HMC
was delivering the web interface on port 2300. Also, this is a straight
up, VMWare workstation installed on Windows 10. Based on what I see in
the network settings for the VMWare Guest (vHMC) it's on a
192.168.47.1/24 network. The attributes of the vHMC network connection
show that the IP is 192.168.47.129. It has a default gateway of
192.168.47.2

The Network Connection setting show it's on a Custom: Specific virtual
network (VMnet8 (NAT)) Frankly, I can't remember why some of these
options were chosen or whether I should change them.

Perhaps someone who has a vHMV running on VMWare workstation on Windows
10 could take a look at their network settings and see how they compare
(if they can access the vHMC web interface from the host PC).

Hello Pete,

Hmmm...what IP would that be?

Check with your network guys.

VMWare has it's own virtual network that the vHMC is on. Closest I can

find on the vHMC is looking at Console Settings and then viewing the
network topology. It has an address of 192.168.47.129. Local IP on laptop
hosting the VMWare Workstation is 192.168.1.114 and I don't see a route to
the vHMC IP running in VMWare...

If you're lucky, it will be handled by the default gateway entries. Try

to ping from the workstation to the HMC. If that works: Congrats. If you
can't connect via Browser or on port 2300 => Firewall in between.

Perhaps the config needs a tweak.....?

Most likely no. Without knowledge of the local network topology involved

at large, almost everything is like trying to shoot into the dark.

:wq! PoC
