Ok so you are doing open network connection,
I rather say use private IP between HMC and Manage system (ie.e use DHCP)
In the HMC go to HMC management --> change network settings --> LAN Adapter (Mostly people use eth0 for private IP, I don't know how you configured)--> Details --> (Select Private) - Autodetection -- DHCMP Server (enable) -- OK.
Do the connectivity test.
Also, if your HMC and VIOS are NOT on same VLAN you don't even have to worry about changing the IP of HMC, you use public IP to get into HMC.
Also, make sure to ask if network is tagged, if so you have to change the PVID as per the new subnet.
If you there is No VLAN Tagging then the setup is as you have now.
Hope this helps.

I created a profile in HMC for a new LPAR and activated it but not yet installed AIX.
Is there a step to make this new LPAR available as vhostX from the VIO server after creating and activating an HMC profile?
I already shared the CD-ROM device from the HMC profile.
Thanks.

Hi All,
Besides the licenses on VIO and LPAR. What's the main difference with the two? I have installed VIO, my manager told me so, because it's like a free hypervisor but I never installed LPAR before. How do you install it? And if you can give more info on the two, that would be great.

Hi All,
i would like to know if it's possible to know all the IP Addresses of all LPAR's interfaces from HMC (without connect into LPAR).

VLAN(7) Miscellaneous Information Manual VLAN(7)
NAME
VLAN - virtual local area network
DESCRIPTION
This manpage provides a brief overview of VLAN (virtual LAN) technology.
VLANs are logical, or network segments that can span multiple physical network segments. A primary benefit of VLANs is that they can iso-
late broadcast and multicast traffic by determining which destinations should receive that traffic, thereby making better use of switch and
end-station resources.
Logical separation using VLAN allows for the logical grouping of PCs, servers and other network resources to behave as if they were con-
nected to the same, physical segment, even if they are not.
HP-UX VLAN is an implementation of IEEE 802.1p/Q standards.
VLAN interfaces can be configured in HP-UX servers using the command (see nwmgr_vlan(1M)) or (see lanadmin_vlan(1M)). HP recommends that
you use for HP-UX Release 11i Version 3 and forward. Interfaces can also be configured using the web-based management tool HP-UX System
Management Homepage (HP SMH).
Each VLAN interface created is assigned a VLAN PPA (VPPA) that is unique across the system and a VLAN ID, that identifies the virtual LAN
it is part of. The VLAN ID is unique on the interface on which the VLAN interface is created.
WARNINGS
The and commands are deprecated. These commands will be removed in a future HP-UX release. HP recommends the use of replacement command
nwmgr(1M) to perform all network interface-related tasks.
