Upgrade Dell EMC Unity VSA to latest version

One of the first article of the series dedicated to the Dell EMC Unity VSA was covering the first deployment and installation phase. In this instance the series continue visiting the options on how to upgrade Dell EMC Unity VSA to the latest edition. In particular this article refers to the steps updating the UnityOS shipping with the virtual appliance.

The same process to upgrade Dell EMC Unity VSA applies to both the operating systems, the firmware, MIBs (Management Information Base), language packs and others. The process is really simple and straightforward. Everything is operated using the GUI with a convenient wizard and even through the command line available from other operating systems (Windows and Linux based) connecting to the Dell EMc UnityVSA appliance.

All these updates plus the full image files are available from the Dell EMC support site searching for the UnityVSA in the product list.

Before proceeding with the update it is recommended to perform an health check just to rule out possible settings or configurations interfering with the process. In addition, it is also a good idea to put the system in maintenance mode to quiesce the file system and perform the upgrade process faster. Another thing to consider is the performance during the upgrade might be degraded as there would be only one storage processor active. At the software image completion the storage processor will be automatically rebooted as part of the Dell EMC UnityOS upgrade process. As an overall timing for completing the update it took less than 30 mins. Times might change depending on the current workloads.
