Patching AIX virtual machines in a private cloud

Share this post:

One of the biggest challenges in a cloud environment is the process of maintaining the virtual images with the proper maintenance after they have been provisioned.  Many times customers who have established AIX patching best practices want to leverage their existing process and bring it to the cloud.  Tivoli Endpoint Manager (TEM) provides an efficient way to manage the patch process across several platforms including AIX.  The TEM patch process uses the TEM standard infrastructure, and one of the challenges with this process for some AIX customers is that it downloads the patches to the local file system for deployment.  This way can be extremely challenging on AIX where disk space is at a premium.  In this article, I describe the process of using an exiting NFS-based patch process and integrating it into TEM.

I do this by building a custom fixlet.

In the Tivoli Endpoint Manager Console, I select Tools > Create New Fixlet.

I then define the fixlet along with the actions to take.

The first action is to create my NFS mount directory.

The next action is to mount the NFS share to the directory that I created in the previous step.

I commit all the previously applied patches to ensure no issues occur in applying the new technology level.

The final step of the fixlet is to actually install the patches.

I do not include rebooting the system as part of the fixlet so that I can control when the reboot occurs.
