Pre-requisites

Prior to upgrading, please ensure the following -

  • Appliance is running version 2.0.2.29. If your current software does not meet this criteria, please contact your StorSimple support to upgrade the appliance to the minimal required version.
  • Navigate to Home → Manage → Hardware and ensure that all the components are healthy (as indicated by green status). If any of the component is not healthy, please contact StorSimple Support team to provide guidance on next steps.
  • Access the StorSimple support site to download the correct version of software. For 2.0.2.29 or higher software, download storsimple-2.0.2.xxx*-patch-install-patch.tar.

  • The software upgrade will start. Once the upgrade is complete, proceed onto the next step as explained below.

Monitor the status of the Cluster

Once the standby controller is successfully upgraded, monitor the status of the cluster by accessing Home Manage Hardware. If the cluster is reported as ‘healthy’, the user can proceed to the next step. Perform the following steps to monitor the status of the cluster.

  • Monitor the status of upgrade by navigating to Home Manage Hardware. Note the presence of an alert bar. This alert bar will be present throughout the upgrade to provide the status of the process.
  • Additionally, this screen has an 'Auto-Refresh' option. This will be enabled by default during the upgrade process. This will continuously refresh the hardware page (at a 15 sec. interval) and allow the user to view the status of the various components. Note that if the user navigates away from the hardware page and returns to it, then the Auto-Refresh will not be enabled by default. The user will need to enable it.

  • Whenever the upgrade status changes, the upgrade alert will also refresh as seen below. Note that the 'View Details' link on the upgrade progress bar and the 'Cancel Upgrade' button in the associated screen are not applicable in this version of software.
  • In the Shared Components view, check the status of ‘Cluster’ component, it will show as DEGRADED which indicates that the standby controller is being upgraded.

  • Also, note that ‘Cluster Node’ will be reported as FAILED.

  • Monitor the screen continuously until the ‘Cluster’ and the standby ‘Cluster node’ shows ‘Healthy’ again as shown below.

  • Once the Cluster component status changes to HEALTHY, it indicates the successful upgrade of standby controller.

Failover and transfer of control

The active controller is now ready to be upgraded to the new software version. The controls will be transferred to the standby controller that will now resume operations as the new active controller. This process is also referred to as “Failover”. The user needs to perform the following steps:

  • The user is required to restart the active controller by clicking on Restart Active Controller button.

  • You will be notified with the following message.

  • Click OK to restart the ‘Active Controller’.
  • During the restart process, the following screen is shown to the user. At this point, the standby controller (with the upgraded software) takes over and becomes the active controller.

  • Once the failover has completed the user is directed to the login screen. Note that on the top right-hand corner, the upgraded software version will be displayed.
  • Login and proceed onto the next step.

Upgrade the new standby controller

Monitor Hardware page by navigating to Home  Manage Hardware and ensure that 'Cluster' and the standby 'Cluster node' are reported as 'Healthy'. All the remaining components on this page should be reported as 'Healthy' (Green Status).

Navigate to Manage Software Upgrade. Repeat the steps listed under Upgrading the standby controller and Monitor the status of the cluster to upgrade the new standby controller.

Restart Active Controller

Once both the controllers have been upgraded,  the active controller 'must' be restarted. This can be done by accessing Home Manage Hardware and clicking on the 'Restart Active Controller' button. After this final reboot, the upgrade is complete.

Upgrade verification

Once the active controller has restarted, ensure that all the components are 'healthy' by accessing Home Manage  Hardware. The final step then in the upgrade process is to verify that the software has been upgraded to the requisite version. Perform the following steps.

  • Navigate to Home Help Technical Assistance.
  • Check the software version under system information to verify that the upgrade was successful. The new software version should be displayed.
