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

ipsec_sameaddr
IPSEC_SAMEADDR(3) Library Functions Manual IPSEC_SAMEADDR(3)
NAME
ipsec_sameaddr, ipsec_addrcmp, ipsec_samesubnet, ipsec_addrinsubnet, ipsec_subnetinsubnet, ipsec_subnetishost, ipsec_samesaid,
ipsec_sameaddrtype, ipsec_samesubnettype - do comparisons for addresses, subnets, SA IDs and address families
SYNOPSIS
#include <freeswan.h>
int sameaddr(const ip_address *a, const ip_address *b);
int addrcmp(const ip_address *a, const ip_address *b);
int samesubnet(const ip_subnet *a, const ip_subnet *b);
int addrinsubnet(const ip_address *a, const ip_subnet *s);
int subnetinsubnet(const ip_subnet *a, const ip_subnet *b);
int subnetishost(const ip_subnet *s);
int samesaid(const ip_said *a, const ip_said *b);
int sameaddrtype(const ip_address *a, const ip_address *b);
int samesubnettype(const ip_subnet *a, const ip_subnet *b);
DESCRIPTION
These functions do various comparisons and tests on the ip_address type and ip_subnet types.
Sameaddr returns non-zero if addresses a and b are identical, and 0 otherwise. Addresses of different families are never identical.
Addrcmp returns -1, 0, or 1 respectively if address a is less than, equal to, or greater than b. If they are not of the same address fam-
ily, they are never equal; the ordering reported in this case is arbitrary (and probably not useful) but consistent.
Samesubnet returns non-zero if subnets a and b are identical, and 0 otherwise. Subnets of different address families are never identical.
Addrinsubnet returns non-zero if address a is within subnet s and 0 otherwise. An address is never within a subnet of a different address
family.
Subnetinsubnet returns non-zero if subnet a is a subset of subnet b and 0 otherwise. A subnet is deemed to be a subset of itself. A sub-
net is never a subset of another subnet if their address families differ.
Subnetishost returns non-zero if subnet s is in fact only a single host, and 0 otherwise.
Samesaid returns non-zero if SA IDs a and b are identical, and 0 otherwise.
Sameaddrtype returns non-zero if addresses a and b are of the same address family, and 0 otherwise.
Samesubnettype returns non-zero if subnets a and b are of the same address family, and 0 otherwise.
