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.

To upgrade to Storage Center version 4.5.6, refer to the Storage Center 4.5 System
Upgrade.

Note You must upgrade the Storage Center software before making hardware changes to

a system.

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. However, the completion of
the installation can take significantly more time to complete in-service as compared to
installing the components during a scheduled service outage.

• Scheduled Service Outage: Components that affect service must be applied during a
scheduled service outage. These components require restarting the Storage Center
controllers to complete the installation. Components that are service optional can also
be applied during a scheduled service outage to speed up installation.

To decide how to apply updates:

1 After downloading an update packages, view update details:

a From the Storage Management menu, select System > Update > Update Status.

The Update Status dialog appears.

b Click Details. The Update Details dialog appears.

2 In the Update Details dialog, view the Update Type column for each component:

For this Update Type … Apply Update Options Include …

Required Component must be installed.

• For a single-controller Storage Center, the update
component affects service.

• For a clustered-controller Storage Center, the update
component can be performed without disruption of service.

Deferrable Service
Affecting

Deferrable Service
Optional

Component installation can be deferred.
Applying the update affects service on all systems. Schedule a

service outage to apply the update.
Component installation can be deferred.

Applying the update can be done either without affecting service
or during a scheduled service outage.

3 After viewing the Update Type for all components included in the update package,

determine how to apply the updates:

• If you intend to install components that affect service, plan for and schedule a service
outage during which to apply the updates. You may also want to install components
that are service optional during the schedule outage.

• If you intend to install components that do not affect service, plan for applying the
updates during a time at which the Storage Center is least busy.

8 Storage Center 5.5 System 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.

Note Do not manually restart the Storage Center controllers during the upgrade process.

Upgrading is a software-controlled process.

When you are ready to apply update components to the Storage Center, do the following:

Phone Home

 To use Phone Home

1 From the Storage Management window, select System > Phone Home > Phone

Home.

2 From the displayed window, select Phone Home Now. When the system reports

success for all Phone Home transfers, click Close.

Installing an Upgrade

Back Up the System

Make sure that backups are up-to-date and Replications are synchronized.

Validate Components

 To validate components

1 From the Storage Management window, select System > Update > Update Ready to

Install - Install Now.

2 On the displayed window, click Validate Components. If Storage Center detects a

problem when validating update components, the Validate Components dialog
displays a summary of validation problems. To re-validate an update package, when
validation results are displayed, click Revalidate Components.

Storage Center re-validates update components and returns the results. Validation
problems are classified as warnings or errors. In general, validation warnings indicate a
connection or cabling issue with a component that prevents the component from being
updated; validation errors indicate that a file required by an update component cannot
be found. When a validation warning or error is displayed, resolve the issue before
continuing with the installation.

Note If Validation warnings and/or errors cannot be resolved, contact Copilot services for

assistance in resolving the errors. Do not force an installation without the assistance
of Copilot support.

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.

• Apply updates that will not disrupt service: This option applies the required portion of
the update package and all updates that do not disrupt service; that is, components
that can be installed in-service.

• Apply updates that will disrupt service (exclude service optional): This option applies
the required portion of the package and all update components that affect service.
Components that are service optional (that is, can be installed in-service) are
excluded.

• Apply all updates: This option applies all updates in the update package, including
all deferrable updates, both Service Affecting and Service Optional. Service
optional components can be installed in-service.

Note Depending on the updates, the estimated completion time for Service Optional

enclosure updates may be significantly shorter using the Apply all updates option
as compared to the Apply updates that will not disrupt service option.

3 Once you have selected the way to apply updates, view information for the update you

have selected:

• Service Affecting: Displays whether the installation of the selected components
affects service.

• Controller Reset: Displays whether the installation causes a controller restart.

• Estimated Completion Time: Time estimate for the installation.

4 Click Continue. A summary of the selected installation options appears.

1 Click on the Controllers icon to view controller status.
2 When both controllers are up, the local port condition may be unbalanced. If so, click

Rebalance Ports. The system rebalances the ports.

3 Verify that both controllers are running the new version of code. From the Help menu,

select About Compellent Storage Center. A window appears. displaying the new
version level.
