Decide How to Apply Updates

Within an update package, an individual update component is classified by how the update component

can be installed.

• The installation process automatically reboots Storage Center controller(s) when required by the

components being updated.

• Disk firmware, when applied in-service, does not require a system boot.

• For dual-controller Storage Centers, installation reboots the controllers in sequence or

simultaneously, depending on the components being updated. A service outage is required when

controllers are rebooted simultaneously.

NOTE: Do not manually restart the Storage Center controllers during the update process.

Updating is a software-controlled process.

1. After downloading an update package, view the Update Details to determine how the update affects

service.

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

Status wizard starts.

b. Click Details. The Update Details page appears.

2. On the Update Details page, view the Update Type column for each component.
