    Perform the upgrade

    Upgrade the system software

    Before you begin

    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.

    • 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.
    Procedure
    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. Select the checkbox if you want the storage processors to reboot automatically during the upgrade. For more information, see Automatically reboot storage processors
    9. Review the planned upgrade and select Finish.
    Results
    The screen shows the progress of the upgrade as both storage processors are upgraded and rebooted.
    If you did not select the option to reboot the storage processors automatically, the upgrade process will pause before rebooting the first storage processor, and wait for your input to proceed with the upgrade.
    Once the software upgrade completes, it is strongly recommended that you also install the latest drive firmware updates for your system. Check the Alerts page for notifications for newly available drive firmware upgrades. Upgrade notification alerts are sent weekly, so you may want to review the alert notifications for the last week, if possible. For additional information on upgrading drive firmware, including drive part numbers and the latest firmware packages available for each, refer to Knowledgebase article 000490700.

    Automatically reboot storage processors

    The default option during a software upgrade is to automatically reboot both storage processors, one-at-a-time, as soon as the software upgrade image is staged and the system is prepared for upgrade. If you like tighter control over when the reboots happen, you can clear this option so that upgrade can be started and staged, but neither storage processor will reboot until you are ready.

    Doing so reduces the duration of the window (approximately by 10-20%) when the storage processors could be rebooting, which makes it easier to plan for a time of reduced activity during the upgrade. If that window is not a factor during your upgrade, then leave the default option of rebooting the storage processors automatically to avoid delays with the upgrade completing.

    Update drive firmware

    This task applies to physical deployments only.
    Procedure
    1. Select the Settings icon, and then select Software and Licenses > Drive Firmware.
    2. Select Obtain Drive Firmware Online to download a new drive firmware package.
    3. Select Install Drive Firmware to upload and install a new drive firmware package to the storage system.
    4. Select Perform Health Checks.
      If the pre-update health check fails, you need to 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.
    5. Select the drive firmware file you want to upload, or one that was automatically pushed to your system by Support.
    6. Select Upload. The drive firmware file is uploaded and installed on the system.
    7. View the results and close.
