Moving VIOS, LPAR's, HMC to different subnet
Hi,
Just joined to new company with one Power 720 Express (8202-E4C) server and have no much experience with IBM systems.
I am trying to move everything I mentioned to different subnet as required by customer contract (currently sitting on same subnet as company lan). Access to this subnet will be controlled by firewall (dedicated physical port).
My idea was first to move HMC than VIOS and LPAR's at the end. Through HMC I could use console access to VIOS and LPAR's so I can control IP settings not worrying losing connectivity to them.
First I moved HMC (management) port and it works as expected (I can access it from old subnet).
Problem is that HMC now can not connect with console to VIOS and LPAR's any more. (Internal error, unable to send command to the managed system)
So my question is how HMC communicates with VIOS and LPAR's?
How can I ensure not to lose console access capability?
Do I just need to configure VIOS and LPAR's with IP's from new subnet and hope that they would be accessible again via console access?
For HMC move I changed IP address and default route on interface. On firewall side for the transition period both subnets can talk to each other - no restriction/blocking).
Thanks.

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).
And if i can know also the "Application" hostname of LPAR from HMC.
Thanks in advance.
Bye

NAME
dhcp - Dynamic Host Configuration Protocol
DESCRIPTION
Dynamic Host Configuration Protocol (DHCP) enables host systems in a TCP/IP network to be configured automatically for the network as they
boot. DHCP uses a client/server mechanism: servers store configuration information for clients, and provide that information upon a
client's request. The information can include the client's IP address and information about network services available to the client.
This manual page provides a brief summary of the Solaris DHCP implementation.
Solaris DHCP Client
The Solaris DHCP client is implemented as background daemon, dhcpagent(1M). This daemon is started automatically during bootup if there
exists at least one dhcp.interface file in /etc. Only interfaces with a corresponding /etc/dhcp.interface file are automatically configured
during boot. Network parameters needed for system configuration during bootup are extracted from the information recieved by the daemon
through the use of the dhcpinfo(1) command. The daemon's default behavior can be altered by changing the tunables in the /etc/default/dhc-
pagent file. The daemon is controlled by the ifconfig(1M) utility. Check the status of the daemon using the netstat(1M) and ifconfig(1M)
commands.
Solaris DHCP Server
The Solaris DHCP server is implemented as a background daemon, in.dhcpd(1M). This daemon can deliver network configuration information to
either BOOTP or DHCP clients. The Solaris DHCP service can be managed using the dhcpmgr(1M) GUI or the command line utilities dhcpcon-
fig(1M), dhtadm(1M), and pntadm(1M).
DHCP Configuration Tables
The Solaris DHCP server stores client configuration information in the following two types of tables:
dhcptab tables Contain macros and options (also known as symbols), used to construct a package of configuration information to
send to each DHCP client. There exists only one dhcptab for the DHCP service. The dhcptab(4) can be viewed and mod-
ified using the dhtadm(1M) command or dhcpmgr(1M) graphical utility. See dhcptab(4) for more information about the
syntax of dhcptab records. See dhcp_inittab(4) for more information about the DHCP options and symbols.
DHCP network tables DHCP network tables, which contain mappings of client IDs to IP addresses and parameters associated with those
addresses. Network tables are named with the IP address of the network, and can be created, viewed, and modified
using the pntadm command or dhcpmgr graphical utility. See dhcp_network(4) for more information about network
tables.
