U6 - Escala Update of AIX 5.3 to 5.3.12.5 (TL 5300-12-05)

 

Document Release 15.0 (09/02/2012)

Preliminary Remarks

Français English

On ne parle plus de Maintenance Level (ML) mais de Technology Level (TL) à partir du niveau d'AIX 5300-04


Ce document décrit la procédure à suivre pour mettre à jour un système en AIX 5.3 au dernier indice technique. Le dernier indice livré par BULL est 5.3.12.5 (il correspond au niveau du fileset bos.mp). Autrement dit Technology Level 12 Service Pack 5 (5300-12-05-1140).

Attention : updater un système vers un niveau de modification inférieur  n'est pas supporté, ce qui reste possible même si le Technology Level est supérieur.

Donc, avant d'updater le système en TL12, il faut vérifier le SP rendu par la commande oslevel -s (5300-<TL>-<SP>-<DATE>). Si le système est  aux indices suivants :

TL0, TL1, TL2, TL3, TL4, TL5, TL6, TL7, TL8 avec SP indifférent

TL9 avec SP inférieur à 8

TL10 avec SP inférieur à 5

TL11 avec SP inférieur à 5

updater vers TL12 SP5 sera effectivement évoluer vers un niveau de modification supérieur. Dans les autres cas, il faudra installer le dernier SP de la TL12 pour se trouver à un niveau de modification équivalent.

Attention : le SP5  est fortement conseillé pour le niveau TL12 (pb de mémoire)

Pour connaitre les derniers Service Packs disponibles, aller à:

https://support.bull.com/ols/product/system/aix/fix/cs/packs/ml/

Attention: Pour cette mise à jour d'AIX, il est nécessaire de mettre à jour également les "Bullenh (Bull Enhancements)".
Attention: si Oracle 9i, 10gR1 ou 10gR2 (inférieur à 10.2.0.3) tourne sur le système, il faudra installer un patch d'Oracle (voir U6.7)

Technology Levels (TL) replace Maintenance Levels (ML) starting from AIX 5300-04 Release.

This document describes the procedure to follow when updating an already existing AIX 5.3 system. The Latest Technical Level delivered by BULL is 5.3.12.5 (according to the bos.mp fileset Level number). So, Technology Level 12 Service Pack 5 (5300-12-05-1140).

Warning : updating a system to a lower modification level is not supported (which is possible even when updating to a higher Technology Level)

So, before updating the system, please check the  Technology and Service Packs levels returned by the oslevel -s command (5300-<TL>-<SP>-<DATE>). If the system level has the following values :

TL0, TL1, TL2, TL3, TL4, TL5, TL6, TL7, TL8 : all  SPs

TL9 : SP less than 8

TL10 : SP less than 5

TL11 : SP less than 5

then, updating to the TL12 SP2 level will lead to update the system to a higher modification level. In other cases, the latest SP for TL12 is needed to be installed.

Warning : SP5 is strongly recommended for the TL12 level ( memory issues )

To know the last available Service Packs, please go to :

https://support.bull.com/ols/product/system/aix/fix/cs/packs/ml/

 

Warning: For this AIX update procedure, it is mandatory to also update the "Bullenh (Bull Enhancements)" product.
Warning: if Oracle 9i, 10gR1 or 10gR2 (less than 10.2.0.3) is running on the system, you must install an Oracle patch (see U6.7)

Procedure Contents

 


 

U6.1 - Media and SRB

  • DVD: AIX 5L V5.3 TL12 Updates (76742834-101) + AIX 5L V5.3TL12SP5 ( 76743315-001)

U6.2 - Cluster Node Update

If the server to be updated is a cluster node, please refer to the HACMP Upgrade procedures at the High Availability Products for AIX WEB site (Bull internal access only), to see if you need to install HA PTFs.

You have to stop HACMP with takeover option on that node, using the smit clstop command, before AIX update.

U6.3 - Precautions

  • In any case, perform a bootable backup of your configuration (rootvg) and save other Volume Groups.
  • To check if some efixes were installed on this system, run :
emgr -l
If you get some, you have to check that the APARs corrected by the efixes are corrected too by the new AIX Release you are going to install, otherwise new efixes will be needed after AIX update. Please call the Support representative for help.
  • It is strongly recommended to run the system in single user mode:
    • Replace the following /etc/inittab line:
      init:2:initdefault:
      with
      init:s:initdefault:
    • If your system resides on a Fiber Disk, do not reboot now, otherwise reboot the system, using:
      shutdown -Fr

U6.4 - Fibre Channel Disk Subsystems Preparation

  • If your system does not include Fibre Channel Disk Sub-systems, just ignore this section.
  • If your system includes Fibre Channel NDAS CX200/300/400/500/600/700 and (or) EMC Symmetrix Sub-systems, check the flare and base software release at the EMC CLARiiON Storage Subsystems WEB site (for Bull employees only). You can, at this point:
    • update the DAS flares
    • update Navisphere 6 to the latest level
    • update Powerpath to the latest level
  • If your system resides on a fibre disk (rootvg on an hdiskpower device)
    • if you need to update Powerpath, perform the following :

      WARNING : a serious defect is reported by EMC about PowerPath 5.5 or 5.5 P01 witch can in various deployments or migration plans change the planning or the use of this product. It is strongly trecommended to wait for the P02 availability which is planned early September 2011.
      • run : pprootdev off then shutdown -Fr

      • stop all the applications, umount the filesystems and varyoff the VGs which reside on hdiskpower devices
      • stop navisphere : rc.agent stop
      • check on which hdiskpower device is rootvg : lspv |grep rootvg
      • let's suppose that rootvg is on hdiskpower<x>, then verify that rootvg hdisk is on the default SP : powermt display dev=hdiskpower<x>
        you must get the following :

        Owner : default=SP <y> , current = SP <y>

      • run : rmdev -dl hdiskpower<x>
      • run : bootlist -m normal -o and check that the first hdisk in the list is affected to the current SP
      • install the last Powerpath release using : smit install_latest
      • restart navisphere : rc.agent start
      • configure Powerpath : powermt config
      • run : pprootdev on then shutdown -Fr
      • after rebooting run : pprootdev fix

    • if you don't need to update Powerpath, run :pprootdev fix

U6.5 - Bull SAN Manager (S@NIT!)

The S@NIT! product is no more supported.

U6.6 - Disk Subsystems

If your system does not include disk subsystems, just ignore this section.
If your system includes disk subsystems, all activity must be stopped: this is OK, since you are running in single user mode.

U6.7 - Install AIX updates using "AIX 5.3 Updates" CD-ROM

  • If the Hypertext Library (Bull documentation for AIX/Escala) is installed, please remove it before updating AIX. You can reinstall it after the AIX update. To remove the Hypertext Library, run:
    cd /
    /etc/hypercd/install -u

  • To be able to install the Updates CD-ROM, perform the following commands:
    mount /opt
    srcmstr &
    /etc/methods/cfg64 &
    /usr/sbin/cron &
    

  • Please, note the current AIX 5.3 oslevel before update, running :

oslevel -s

  • To install the updates, insert the "AIX 5.3 Updates" CD-ROM then run:
    smit update_all
    In the SMIT menu, select the options as below and run the update:
    INPUT device/directory for software: [/dev/cd0]
    SOFTWARE to update [ update_all ]
    ACCEPT new license agreements? yes

To install the updates, insert the "AIX 5.3 Updates SP5" CD-ROM then run:

smit update_all

In the SMIT menu, select the options as below and run the update:

INPUT device/directory for software: [/dev/cd0]
SOFTWARE to update [ update_all ]

ACCEPT new license agreements? yes



  • If you need to install a more recent Service Pack, you can download it from :

https://support.bull.com/ols/product/system/aix/fix/cs/packs/ml/

then install the Service Pack running :
smit update_all
  • If you get the following message at the end of the update process:
  • ***** ATTENTION *****
     The boot image you just created might fail to boot because
     the size exceeds the system limit. For information about
     fixes or workarounds, see /usr/lpp/bos.sysmgt/README.

    your system may not boot, depending on your machine model:

    • If your machine is a Power5, Power5+, Power6 or Power7 Escala model, you will have no problem to boot.
    • If your machine model is one of the following Escala models: PL220 / PL240 / PL420 / PL820 / PL1600 / PL3200, then the firmware of the machine must be set at the latest level to be able to boot. Check the firmware at:

      http://techsupport.services.ibm.com/server/mdownload/download.html

      and do not worry if you still get the same warning message, running the bosboot command after rebooting your system.
    • On other models, it is strongly recommended to remove some not used filesets from the system that would result in a smaller boot image (<12 MB), for example some Graphic adapters filesets (run lslpp -l |grep -i graph).

      If you cannot remove any fileset, you will have to access the firmware command line prompt (OK prompt), which usually appears as an option in the SMS menus, each time you reboot the system (not very convenient...). That means that you will have to type the following two commands, at the firmware command line prompt each time you need to boot your system:
      setenv real-base 1000000
      reset-all

WARNING: If Oracle 9i, 10gR1 or 10gR2 Database (less than 10.2.0.3) is running on the system, you must install an Oracle Database patch to bring the OS and Database environments to the correct levels.
Please follow these steps :

  • Navigate to http://metalink.oracle.com/ and sign into MetaLink
  • Select the "Patches & Updates" tab
  • Select the "Simple Search" link and enter Patch Number 5496862, select Platform AIX5L Based Systems(64-bit) and desired Oracle version
  • Proceed to download the desired patch. If the patch is unavailable, please contact Oracle Support for assistance.

U6.8 - Install the Bull Enhancement

  • If you use RSF (Remote Services Facilities), you must create a directory as follows to preserve the RSF configuration:
    mkdir /tmp/rsf.rsflite.upd.sv
  • Insert the Bull Enhancement CD-ROM and run:
    smit install_latest
    Select:
    INPUT device/directory for software : [/dev/cd0]
    and install all the filesets.

    The installation will fail because of the EMC.AIX package. The requisite failure message related to the EMC.Symmetrix.ha.rte and EMC.CLARiiON.ha.rte filesets is normal since you do not have any High Availability software installed on your machine.

    Please refer to section Install From Scratch: New and Complete Overwrite / Install Bull Enhancement Packages of the SRB AIX 5L for POWER Version 5.3 TL12 SP2 & Bull Enhancement V6.1.5 (86 A2 32EJ Rev.33).

U6.9 - Reboot the system

  • If you use NIS, it is strongly recommended to remove the bos.net.nisplus fileset.
  • Before rebooting, restore the multi-user mode by replacing in /etc/inittab the line:
    init:s:initdefault:
    with
    init:2:initdefault
  • Reboot now the system, by running:
    shutdown -Fr
  • It is recommended to perform a backup of the system (using the smit mksysb command).

    Warning:
    If LANG=fr_FR, when running the smit mksysb command, you may get the following error message:

    /usr/bin/mksysb[33]: 2004,68: 0403-057 Erreur de syntaxe.

     

    In such a situation, you must use the following workaround:
    run the command export LANG=C before running the mksysb.

U6.10 - Tasks to perform after the update

  • If this update is performed within a HACMP cluster, restart HA using the smit clstart command, and update the other cluster node(s).
  • Otherwise, you can now perform the varyonvg command on the de-activated Volume Groups, then mount the filesystems back.
  • Run:
    oslevel -s
if you don't get 5300-12-05-1140 (in case of SP5 installation), run oslevel -sl 5300-12-05-1140 to get the filesets which cause the AIX level to be wrong. If you don't use these filesets, just remove them (installp -u <Fileset>), otherwise call your support representative.
