Update Component Types
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.
• Service Affecting or Service Optional: Service Affecting components can be installed
only when the Storage Center is temporarily taken out-of-service to perform the update;
Service Optional components can be installed either when the Storage Center is in
service or during a scheduled outage.
The following table shows which components affect service during installation.
** Only the following enclosure firmware allow Service Optional installation:
• FC SBOD enclosures, Model EN-SB4X16
• FC SATA enclosures, Model EN-SA2X16
All other enclosure firmware installation is Service Affecting.

An upgraded Storage Center retains the existing configuration setting for Automatic
Updates. This section describes how to control the processes of Check Update and
Download Update.
Note Once downloaded, package updates are not automatically installed. A user with
administrator must validate and then initiate installation of an update package.
