Dell PowerStore T and PowerStore Q Software Upgrade Guide

PDF

Upgrade the software on a PowerStore T model 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. Open PowerStore Manager.
  2. Select the Settings icon, and then select Upgrades in the Cluster section.
  3. 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.
  4. 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.
    NOTE:The cluster temporarily stops recording performance metrics when the primary node of the primary appliance reboots during the software upgrade.
  5. After you are returned to the login screen, close the browser session and open a new session before logging in again to refresh the UI.
    NOTE:Following the upgrade, if you do not open a new browser session before logging in again, PowerStore Manager still displays the UI for the previous PowerStoreOS version. New features will not be available until you refresh the browser.

Results

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.

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

NOTE:Beginning with PowerStoreOS 4.0.x and later, 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 package and then Upgrade again. Contact your service provider for further assistance with nondisruptive upgrade (NDU) failures.
