Dell PowerProtect DD Management Center (DDMC) 7.9 Installation and Administration Guide

Viewing replication topology to investigate error conditions

When the Topology view is selected on the Replication > Overview page, it shows the relationships of the site's configured replication contexts and uses color-coded status indicators and other map controls to let you easily locate and drill-down to investigate error conditions.

Use the Type menu to select the replication types that are shown in the map work area (MTree, directory, collection, and on-demand files). If a replication type has not been configured among the site's replications, its checkbox in the menu is disabled. If a type is enabled but de-selected, those node relationships do not show on the map.

A slider on the map controls the scope of replication contexts that are shown in the work area display.

The inset is a miniature representation of the map and its scope is controlled by the slider manipulation. The inset itself can be selected and moved around to include or exclude systems in the map work area.

Replications statuses between systems are shown with color-coded directional lines, which will show red if any of the replications is in error. Hovering over the line shows the number of replication pairs and a count for each status level.

The action buttons above the graph correspond to the selected item in the graph. Selected items can be:

• System (Buttons for system details and launching DD System Manager will show.)
• Tenant Unit (Buttons for tenant or tenant unit details will show.)
• Property or Data Set (MTree, directory, collection, etc.)

Use the actions items to show Related Items and Connected Items available for any object selected in the graph to show an in-depth view of all replication pairs that are configured. Items related to a selection will include all pairs with direct replications or cascades connected to the selected items. The Connected Items button will filter to show a connected graph containing the selected item. (A graph is connected if there is a path between every pair of graph nodes.)

The right panel lists the Replicated Pairs (of highlighted systems in the map work area or all contexts if nothing is highlighted), showing the type of context, source and destination systems, status, with a link to additional details. Selecting a context activates the Pair Details control.
