Preparation
The latest Technology Level and Service Pack releases for AIX on Pseries can be found here
--> IBM Pseries fixcentral
http://www-912.ibm.com/eserver/support/fixes/fixcentral
Download your required package, it is a good idea to check "Yes, include Technology Level XXXX-XX with the Service Pack" just in case there are any filesets required from the Technology Level
Either place the files in a directory on the server to be updated or burn them to a CD
Then login to the server as root and run lppchk -v, this will check to see if all the currently installed software is correctly entered in the Software Vital Product Database (SWVPD) and that all filesets have all the required requisites and are completely installed.
It is a good idea to check if the hardware microcode is up to date
Ensure all hardware including external devices are connected and powered on
Check for any existing faults on the server using the command errpt -a and fix as required
Ensure that there is enough free disk space available
Create a mksysb to back up the root volume group, also run a full system backup to backup all partitions on the server
It is advisable to reboot the server before updating it to ensure that if the server fails to reboot the cause can be more easily determined and not attributed to the update process
Performing the update
1. Insert the AIX technology level CD into the CD drive or change directory into the directory containing the software and verify that the software is present and correct
2. Type smitty update_all
3. Select required values in entry fields, for example it is advisable to apply the updates and then commit them later once you are sure the update was successful
4. Review /smit.log for any errors
5. Reboot the server by typing shutdown -Fr
6. After the reboot verify that all the currently installed software is correctly entered into the Software Vital Product Database (SWVPD) by typing lppchk -v
7. Check for system errors by typing errpt -a
Upgrade AIX from version 5.3 to version 6.1
This document describes updating a p505 server from AIX 5.3 to AIX 6.1
Preparation
IMPORTANT - Read the release notes for the version of AIX you are upgrading to
The release notes for AIX 6.1 can be found here -->
http://publib.boulder.ibm.com/infocenter/systems/scope/aix/index.jsp?topic=/com.ibm.aix.resources/61relnotes.htm
Note - POWER3 processors are NOT supported by AIX 6.1
• Ensure you do a full system backup and ensure that you create a mksysb before upgrading AIX.
• Check if the hardware microcode is up to date - see the microcode update document on this web site.
• Ensure all hardware including external devices are connected and powered on.
• Check for any existing faults on the server using the command errpt -a and fix as required.
• Ensure that there is enough free disk space available.
• On the server you want to upgrade check what disk rootvg is installed on. To do this type lsvg -p rootvg. In this case I found rootvg to be installed on hdisk0.
• Check that the CDROM drive is listed in the bootlist before the hard disk by typing bootlist -m normal -o If the CD drive is not listed before the hard disk i.e. hdisk0 cd0, then change the boot order by typing bootlist -m normal cd0 hdisk0.
• It is advisable to reboot the server before updating it to ensure that if the server fails to reboot the cause can be more easily determined and not attributed to the update process. To reboot the server shutdown any applications and then type shutdown -Fr.
• Also run lppchk -v, this will check to see if all the currently installed software is correctly entered in the Software Vital Product Database (SWVPD) and that all filesets have all the required requisites and are completely installed.
Upgrading
Put the AIX 6.1 base operating system CD or DVD into the CD/DVD drive
The console for this upgrade was a dumb vt100 type terminal, the display may be slightly different for a graphical display
Reboot the server type shutdown -Fr
The server should boot off the media in the CD/DVD drive and a screen should display some selectable options as follows
--------------------------------------------------------------------------------------------------
1 = SMS menu 5 = Default bootlist
8 = Open Firmware 6 = Stored bootlist
--------------------------------------------------------------------------------------------------

IVM
IVM: Integrated Virtualization Manager. This is a management interface that installs on top of the VIOS software that provides much of the HMC functionality. It can be used instead of a HMC for some systems. It is the only option for virtualization management on the blades as they cannot have HMC connectivity.
