Uninstalling updates

It might be necessary to remove an update from a system or group of systems. Use the Uninstall updates task to do this. Not all updates support the uninstall task. For updates that cannot be uninstalled, it might be possible to roll them back to an earlier version by installing an older version on top of the current one.

Procedure

  1. From the Update Manager summary page, click Show installed updates. The Show Installed Updates page is displayed.
  2. Select a system or system group in the Selected systems field. Click Browse to see a list of systems to choose from.
  3. Click Show installed updates. A table of installed updates is displayed.
  4. Select each update that you want to uninstall.
  5. Click Uninstall updates. The Uninstall wizard Welcome page is displayed.
  6. Clear Show this welcome page next time if you do not want to see the Welcome page next time.
  7. Click Next. The Updates page is displayed.
  8. Select each update that you want to uninstall and click Add.
  9. Click Next. The Systems page is displayed.
  10. Select each system or system group from which you want to uninstall the updates and click Add. All selected updates that are installed on these systems will be uninstalled. If you select a system group, the updates are uninstalled from those systems that are a member of the group at the time the uninstallation task runs.
  11. If some of the updates are for AIX® systems, and you had not already specified the necessary AIX options on the Settings page, it is displayed so that you can choose these options.
  12. Click Next.
  13. Optional: The Manual Uninstall Required page might be displayed. It is displayed only when an update selected for uninstallation must be manually removed.
    1. Click View under the Uninstallation Instructions heading to see the manual instructions for each update to be uninstalled.
    2. Read the instructions and decide to run them now or later.
  14. Click Next. The Restarts page is displayed. All selected systems are displayed in the table even if they do not require a restart. For each system, the highest restart impact is listed. The systems are sorted in this table with those of highest restart impact listed first.
  15. Automatically restart as needed during installation is selected by default. Clear this box if you do not accept the restart requirements. If you clear the Automatically restart as needed during installation box and updates are uninstalled that have pending restarts, then the uninstallation task will complete with errors and some uninstalls might not be attempted if a dependent update requires an immediate restart.
  16. Click Yes in the Restarts Required column for a system to view all updates to be uninstalled on the system and their individual restart requirements. This view is specific to the selected system. It shows all the updates that will be uninstalled on that system and the restart value for each. You cannot change the information on this page. If you do not accept the restart requirement, click OK to return to the Uninstall wizard, click Back, and then remove systems or updates. If you have selected system groups as the target for the uninstallation task, the list of individual systems in these groups is not determined until the task runs. You are presented options only for those systems that were individually selected. Group membership is not determined until the task runs.
    The exact wizard options that are displayed vary, depending on the type of resource that is being updated. These are some of the possible values:
    Restart immediately after update is installed
    The restart must be performed before other updates can be installed or uninstalled.
    Restart after all updates are installed
    The restart can be performed at the end of the install or uninstall task.
    None
    There is no restart indicated for the system or resource.
  17. Click Next. The Summary page is displayed.
  18. Review the information on this page.
    • If the information is correct, click Finish. A panel is displayed for you to specify notification and schedule settings for the task being launched by this wizard.
    • If some information is incorrect, click Back to go to previous pages and correct the information, or click Cancel to cancel the entire process.

What to do next

If an update cannot be uninstalled, it might be possible to roll back the installed update by installing an older version of the update. The older update can be installed if the older update is applicable to the system.
