3 Perform the upgrade Topics: • Upgrade the system software • Update drive firmware • Update language packs Upgrade the system software Prerequisites Updates are made when new software or firmware is released. Depending on the implementation, you can obtain updates from online support or from your service provider. If you have ESRS enabled, you can contact support and request that they automatically push down the latest software or firmware to your system. NOTE: It is recommended to always upgrade to the latest drive firmware before performing a software upgrade to help mitigate any nondisruptive upgrade issues. If newer firmware is available for your system drives, you receive an alert in Unisphere that updated firmware is available. When upgrading from Unity releases 5.1 and later, the Pre-upgrade Health Check will notify you before a software upgrade if newer drive firmware is available for your system. ● Perform a system health check about a week before upgrading your software or firmware to ensure that you have time to resolve underlying problems that may prevent a successful update. ● When you upload a new upgrade file onto your system, it replaces the previous version. There can only be one upgrade candidate on the system at a time. ● You will be prevented from using Unisphere or the CLI to make configuration changes to the system while the upgrade is in progress. ● Unisphere may be temporarily disconnected during the upgrade when the primary storage processor reboots, and it may take a few minutes to be automatically reconnected. Steps 1. Under Settings, select Software and Licenses > Software Updates. 2. Select Perform Health Checks to perform the health check independently of an upgrade, or several days or weeks prior to a planned upgrade. If the health check fails, you must resolve the problem before performing an update. If the health check does not fail, but displays warning messages highlighting potential issues, you can choose to check and correct these issues, or ignore these messages and proceed with the update. 3. Select Download New Software to download a new software upgrade image in advance of starting the upgrade. 4. If you downloaded the software manually, save the upgrade file to the local computer from which you are running Unisphere. Do not change the name of the file. 5. Select Start Upgrade. 6. If you have not performed a system health check recently, select Perform Health Checks. This enables you to identify and resolve any issues that may have appeared in the system after the last health check. 7. There are multiple possible options for Select New Software. They may not all be available at the same time. Select one of the following options and click Next: ● No files available for download: Choose File to upload an image previously downloaded to your system. ● Use Candidate Software: This image was previously uploaded to your system by a user. ● Use Latest Image: This image was automatically pushed to your system by support. ● Upload a File: If there are other images available on your system, but you want to upload a file now by navigating to a previously downloaded image file on your local machine. 8 Perform the upgrade
