Upgrading the operating system of the IBM Spectrum Control server from AIX 7.2 to AIX 7.3

About this task

The following steps help you to upgrade the server operating system from AIX 7.2 to AIX 7.3 where IBM Spectrum Control version 5.4.10.2 or later is installed. This includes stopping the required services, resolving potential upgrade issues, and verify the health of your Db2 instance and IBM Spectrum Control software.
Important: Take a full system backup or VM snapshot backup of the IBM Spectrum Control server and read all the steps thoroughly before starting the upgrade process.

Procedure

  1. Prepare the system for operating system upgrade.
    1. Login to the AIX 7.2 server by using root user.
    2. Stop the services of the IBM Spectrum Control server. For more information, see Stopping the IBM Spectrum Control servers by using scripts
    3. Switch the user to the Db2 instance owner (usually db2inst1) by using the command su - db2inst1.
    4. From a command shell, run the following command: 
      db2stop
  2. Make sure to take the backup of the system before proceeding to operating system upgrade.
  3. Follow the operating system upgrade steps from IBM AIX official documentation. For more information, see Migrating to AIX 7.3
    1. After the successful upgrade, make sure that the system is up and running.
    2. Verify that the AIX server version and kernel version are updated to AIX 7.3
  4. After successful operating system upgrade, check Db2 instance (usually db2inst1) is active and running.
  5. If Db2 instance is not active and running, then switch user to the Db2 instance owner (usually db2inst1) by running the command su - db2inst1. For more information, see Db2 services do not start when you restart the system on a UNIX platform
  6. From a command shell, run the following command: 
    db2start
  7. Open the IBM Spectrum Control GUI and verify the status of all the components.
  8. Installed IBM Spectrum Control version 5.4.10.2 can now be upgraded to the latest version by following IBM Spectrum Control upgrade process. For more information, see Upgrading and migrating.
