How do I perform Patch Installation on My Powerscale Cluster?

I have been using Isilon simulator for a long time to test some features and prepare myself to some projects. Knowing that this is a home environment, I am also performing patch installations when I have time.

Lets first power on the Powerscale nodes on my Vmware Workstation. We will need to wait some time for all nodes to totally up and running.

Lets check if we are able to login from the cli and run "isi status" to check the cluster status.

Next, we will need to download the Rollup Patch from the Dell Technologies Support page. After downloading we will need to extract the file.

You will see that the contents of the file similar to below; here we will need to upload the file with the pkg extension to the /ifs/data/Isilon_Support/ . 

I am using FileZilla to perform the upload

I can verify that the file is there.

Here we are ready to Perform the code upgrade. This part really important since we are here only performing the code upgrade, in a real work scenario, you will need to contact Dell Technologies for your Isilon/Powerscale cluster to checked and get readiness for the upgrade. There might be several things to check depending how you are utilizing your cluster and the state of your cluster.

Apart from that, there are 3 different ways that you can perform the upgrade.

1. Parallel Upgrade
2. Rolling Upgrade
3. Simultaneous Upgrade

You may check the Dell Technologies article OneFS Upgrades Info Hub to read more about the ways and more.

Here were are now ready to perform the upgrade. You may perform the upgrade from the webui, however I found it easier to use cli. As this is a home environment for me, I will be using simulataneous option to perform the upgrade. Thus, I will be running "isi upgrade patches install 9.3.0.5_GA-RUP_2022-03_PSP-1956.pkg --simultaneous"

This command may display some additional information that will be performed during patch installation, such as removal of deprecated patches. Finally, we are prompted to proceed, and we need to type 'yes' to continue.

Since I am performing a simulataneous upgrade, it warns me that this operation will result in lost connectivity.

You may quickly check "isi upgrade patches list" to list the patches and their status

After the cluster are totally rebooted, we can verify again with the above command to see the patch is installed successfully, and deprecated patches were removed.

Thanks for reading.
