AIX How to exchange hostname and IP address between two AIX servers?
Hi all,
I am trying to exchange hostname and IP address of two AIX machines.
But i am confused as how to change it ?
do i need to use "smitty mktcpip" or "smitty tcpip" ?
what is the difference between smitty mktcpip and smitty tcpip ?
Also anymore steps to follow or just updating using smitty is enough (hoping that no reboot is required)
Also below is the procedure i want to use for the whole process of swapping hostname and IP address:
1) remove server A from network and update hostname and IP address (to Server B's hostname and IP) using smitty
2) move network connection cables from server B to server A
3) update hostname and IP of server B (to that of server A's old values)
4) attach network cables removed from server A to server B
Does this procedure is good to go ?
Thanks in advance!

ipa-replica-prepare
ipa-replica-prepare(1) IPA Manual Pages ipa-replica-prepare(1)
NAME
ipa-replica-prepare - Create an IPA replica file
SYNOPSIS
ipa-replica-prepare [OPTION]... hostname
DESCRIPTION
Generates a replica file that may be used with ipa-replica-install to create a replica of an IPA server.
A replica can only be created on an IPA server installed with ipa-server-install (the first server).
You must provide the fully-qualified hostname of the machine you want to install the replica on and a host-specific replica_file will be
created. It is host-specific because SSL server certificates are generated as part of the process and they are specific to a particular
hostname.
If IPA manages the DNS for your domain, you should either use the --ip-address option or add the forward and reverse records manually using
IPA plugins.
Once the file has been created it will be named replica-hostname. This file can then be moved across the network to the target machine and
a new IPA replica setup by running ipa-replica-install replica-hostname.
A replica should only be installed on the same or higher version of IPA on the remote system.
