Sidebar

The side bar is the vertical frame on the left side of the GUI window. The side bar contains the navigation tree, which is a series of hierarchical links to different configuration and management features in the Serval filer. The navigation tree has a horizontal scroll bar for options in the tree that extend past the configured width of the sidebar. The navigation tree contains expandable and collapsible options that allow you to directly link to specific features of the Serval filer.

Note!

The navigation does not contain any hot links at the top level. The top level serves as a heading that summarizes the features contained in that expandable section. The hot links are contained within each expandable section.

· To expand an option, click the plus sign (+) to the left of the option. The option is fully expanded when it changes from a plus sign to a minus sign (-).
· To collapse an option, click the minus sign (-) to the left of the option. The option is fully collapsed when it changes from a minus sign to a plus sign (+).
The Side bar contains the following options:
· System. For more information about configuring system parameters, see "Viewing System Parameters"
· Storage. For more information about setting storage parameters, see "Managing Storage"
· Network. For more information about setting network parameters, see "Configuring Network Parameters"
· Backup (NDMP). For more information about setting NDMP backup and restore parameters, see "Monitoring Network Backup"
· Setup Wizard. For more information about the Setup Wizard, see "Using the Setup Wizard".
When you expand these options, you see icons that represent text documents. These icons indicate the screens where you perform configuration and management tasks.
The side bar is available on every GUI screen.

Active Window

The active window is the majority of the Serval's GUI window. The active window is the area that contains the entry fields, buttons, pulldown list boxes, checkboxes, and other information elements that you actually use to configure and manage the Serval.
The active window changes whenever you click a Next, Back, Cancel, Continue, or Apply button, or whenever you click a different link in the navigation tree. As a result, the elements contained in the active window are not available on every GUI screen.
