    Perform the upgrade

    Upgrade the system software

    Before you begin

    Updates are made when a new version or patch is released, or when new information is discovered. Depending on the implementation, you can obtain updates from online support or from your service provider.

    • To ensure that you have time to resolve underlying problems that may prevent a successful update, perform a system health check about a week before installing an upgrade.
    • 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.
    First, perform a system health check. A health check is a series of checks on the state of your storage system. Performing a system health check helps ensure that no underlying problems exist that may prevent a successful update. Then obtain and install software updates.
    Procedure
    1. Select the Settings icon (in the top right of the page), and then select Software and Licenses > Software Updates.
    2. Select Perform Health Checks.
      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.
    4. Save the upgrade file to the 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. Decide whether to upload a new software image or install a software image that has already been uploaded.
    8. If you decide to upload a new software image, select the file you want to upload.
    9. Decide whether you want the storage processors to reboot automatically during the upgrade. For more information, see Automatically reboot storage processors
    10. 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.

    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 disk firmware

    This task applies to physical deployments only.
    Procedure
    1. Select the Settings icon, and then select Software and Licenses > Disk Firmware.
    2. Select Obtain Disk Firmware Online to download a new disk firmware package.
    3. Select Install Disk Firmware to upload and install a new disk 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 disk firmware file you want to upload.
    6. Select Upload. The disk firmware file is uploaded and installed on the system.
    7. View the results and close.

    Update language packs

    Procedure
    1. Select the Settings icon, and then select Software and Licenses > Language Packs.
    2. Select Obtain Language Pack Online and download a language pack file to your local system.
    3. Select Install Language Pack to launch the Install Language Pack wizard.
    4. Select the language pack file you want to upload.
    5. Select Upload. The language pack is uploaded and installed on the system.
    6. View the results and close.
    7. Select the My Account icon and select Preferences.
    8. Select the preferred language from the Language list.
