Upgrading to Storage Center 5.
Introduction If configured to do so, Storage Center automatically checks for updates. However, once an update is downloaded to your system, you must manually install the upgrade. For more information about configuring the Storage Center upgrade process, refer to the Storage Center 5.5 User Guide. You cannot upgrade directly to Storage Center 5.5 from versions prior to Storage Center 4.5.6. You must first upgrade to Storage Center 4.5.6 and then install the Upgrade Package that manages system updates.
Types of Update Components Types of Update Components Within an update package, an individual update component is classified by how the update component can be installed: • Required or Deferrable: Required components must be installed as part of the update; Deferrable components can be installed at a later time.
Downloading an Available Update Storage Center can automatically download updates. To manually download an available update: 1 From the Storage Management menu, select System>Update>Update Status. The Update Status dialog appears. 2 Click Download Now. As Storage Center downloads the update, status appears in a separate dialog.

Field Description Controller Reset Indicates whether the update package installation requires restarting the controllers: • For a single-controller Storage Center: restarting the controller always affects service. • For a clustered-controller Storage Center: If the upgrade is service-affecting, the controllers are restarted simultaneously. If the upgrade is not service-affecting, the controllers are restarted in sequence.

This dialog provides details for all components included in the update package.
Deciding How to Apply Updates The options available for applying updates to the Storage Center are dependent on the Storage Center configuration (single- or clustered-controller, enclosure types, and disk types) and the update component types included in the update package. Applying updates to the Storage Center can be performed: • In Service: Components that do not affect service or are service optional can be applied in background mode while the Storage Center is in service.
Installing an Upgrade Installing an Upgrade The install process automatically restarts the Storage Center controllers. For clusteredcontroller Storage Centers, the Install process restarts the controllers in sequence or simultaneously, depending on the components being updated. Because the Install process automatically restarts the Storage Center controllers, perform an installation only when you are ready to restart the Storage Center.
Install Update When the system reports that all installation components have been successfully validated, you can install the update. To install an update 1 Click Install Update. 2 From the displayed window, select the component updates you want to apply to the Storage Center: • Apply the required portion of the update package: This option applies only the required portion of the update package.
