AIX Upgrade, postinstall actions
Before upgrade
Save your ssh key from /etc/ssh directory
After upgrade
environment
Check /etc/environment:
- change TZ to Europe/Belgium (reboot required)

disks path and settings
Update the path setting with the script /home/scripts/bin/change_disk_param.sh -f and reboot if needed (check the output)
inittab
Check /etc/inittab, to remove unused entries:
for i in pconsole xmdaily webserverstart sniinst atmsvcd mkatmpvc do rmitab $i done
sendmail
Copy the optimized /etc/sendmail.cf from nimsrv, because it's modified during upgrade:
scp -p /etc/sendmail.cf labotest:/etc/mail
The sendmail.cf file must contain the following Smart Relay Host (DS):
[root@safewatchh]/root# grep DSsmt /etc/sendmail.cf DSsmtp.be.dom.com
inetd.conf
Optimize the /etc/inetd.conf to have less entries as possible, the following must be commented: ntalk, xmquery, wsmserver
rc.tcpip
Optimize the /etc/rc.tcpip to have less entries as possible, minimum is portmap and xntpd, and optionally inetd, sendmail
SSH config
Change the SSH config file, to listen on IPV4 only: /etc/ssh/sshd_config
Port 22 Protocol 2 #AddressFamily any ListenAddress 0.0.0.0 #ListenAddress ::
crontabs
For user esaadmin, comment the line:
0 3 * * 0 /usr/esa/sbin/esa_awareness
For user root, remove the following lines:
55 23 * * * /var/perf/pm/bin/pmcfg >/dev/null 2>&1 #Enable PM Data Collection 59 23 * * * /var/perf/pm/bin/pmcfg -T >/dev/null 2>&1 #Enable PM Data Transmission
Additional packages
Install additional packages if not installed:
- Java6_64.sdk
Update old packages
Finish the upgrade if needed, and upgrade additional non AIX software:
- To check which filesets are not at right AIX level:
instfix -ci | grep :-:
Filesystems used space
Check filesystem space
Check User and Group
Check if all files for user and groups are consistent, and automatically correct errors:
pwdck -y ALL
grpck -y ALL
Only after AIX migration
- Copy again the /etc/motd from nimsrv
- Remove files and directories used for migration into / directory (.SPOT .image* image* lpp_name liblpp.a bosinst.data /root/.rhost …)
- check the number of process per user: lsattr -El sys0 -a maxuproc , if less than 2048, change it with: chdev -l sys0 -a maxuproc=2048
