Step 7 - Edit the /etc/hosts file on drs_engine2
1.
First of all create a copy of the
/etc/hosts
file that is shipped from factory with the AIX command
cp /etc/hosts /etc/hosts.factory
.
2.
Open the /etc/hosts file with an editor of your choice, for instance use vi (AIX command to start vi
and open the file is
vi /etc/hosts
).
If you are not familiar with AIX editors, we suppose you use
xedit
, an X-window based editor.
For the latter, you first need to start an X-session. Start the X-session with the AIX command
startx
(see
startx
manpages for details by issuing
man startx
). Then open the /etc/hosts file with
the AIX command
xedit /etc/hosts
, this will open a graphical editor session.
Change the all the preconfigured addresses according to the table you have prepared in Step1.
Only change these addresses, do not change addresses not listed in the table above, or any
words in the /etc/hosts file. Change the addresses in all stanzas of the /etc/hosts file. That is, you
have to change five addresses.
3.
Save the file and exit the editor by pressing Save and Close on the scroll bar.
Step 8 - Change the TCP/IP addresses for the interfaces en2 and en3
1.
From the AIX command line start SMIT

Press
Enter
to change. In the
