Dell PowerStore T and Q Software Upgrade Guide

PDF

Upgrade the software on a PowerStore T or PowerStore Q cluster

Use PowerStore Manager to upgrade the PowerStoreOS and node firmware on the cluster.

Prerequisites

Ensure that a Pre-Upgrade Health Check has been performed at least seven days before upgrading the PowerStoreOS.

Steps

  1. In PowerStore Manager, go to Settings > Upgrades.
  2. If the software upgrade package has not yet been uploaded to PowerStore Manager, follow the upload instructions in PowerStore T and PowerStore Q upgrade overview.
  3. Select the software upgrade package in the Software Packages table, and select Upgrade.
    The software upgrade takes approximately one hour to one and a half hours to complete per appliance. During the software upgrade process, the primary node of the primary appliance fails over to the secondary node of the appliance and you are disconnected from PowerStore Manager. You can log back in to PowerStore Manager after the failover process is complete.
    NOTE:The cluster temporarily stops recording performance metrics when the primary node of the primary appliance reboots during the software upgrade.
  4. If the Software Upgrade Complete dialog box is displayed when the upgrade is complete, click Reload to refresh the PowerStore Manager interface.
    Otherwise, close the browser session and open a new session or reload the page in the browser to refresh the PowerStore Manager interface.
    NOTE:If you do not refresh the PowerStore Manager interface, the UI for the previous PowerStoreOS version is displayed. New features are not available, and unexpected behavior may occur until you refresh the PowerStore Manager interface.

Results

Changes to the column layout settings in PowerStore Manager do not persist when the PowerStoreOS is upgraded. When a new version of the PowerStoreOS is installed, the column layout settings in PowerStore Manager tables reset to their default layout.

NOTE:Beginning with PowerStoreOS 4.0, if the software upgrade fails and successfully rolls back to the previous operating system version, the system automatically recovers. You can retry the upgrade by selecting the software upgrade package and then clicking Upgrade again. Contact your service provider for further assistance with software upgrade failures.
