View Protection dashboard

Each category has a round, colored icon with the number of storage groups in the state corresponding to the color. To view the storage groups that are in the states indicated, you can click the row which brings you to the technologies storage group list view that is filtered to show only the applicable storage groups for the selected state.

The color coding - represent the states as follows:

Normal - Green; Warning - Yellow; Error - Red; Unprotected - Gray.

Clicking a category opens the Replication Dashboard for that particular category, for example, clicking Clone opens the Clone Storage Groups list.

The SRDF Topology View visually describe the layout of the SRDF connectivity of the selected storage system in Unisphere.

It calculates this with a maximum of two hops, for example, Symm A has SRDF Groups to Symm B, which has SRDF Groups to Symm C, if a fourth storage system Symm D has SRDF Groups to Symm C but is not connected to Symm A or Symm B, it is not shown as it is outside the two hop count for the Array that Unisphere is managing. All types of SRDF Groups are used to calculate this view.

There are two components which make up the topology view, nodes and edges. A node is the storage system and the edges are the connectivity between the storage systems.

The edges are color coded in the familiar traffic light system. The colors are Green, Yellow, and Red.

Green edges indicate that the state of the connectivity between two nodes (Arrays) is Good.

Yellow indicates that the connectivity between two nodes is degraded. Degraded in this case means that one or more SRDF Groups between the two arrays are either in a Transmit Idle state, or have some ports in an SRDF Group that are offline.

Red indicates that the state of the connectivity between two nodes is Critical. Critical in this case means that one or more SRDF Groups between the two arrays are Offline, or one or more SRDF Groups contains ports that are all offline.

The edges are also drawn differently depending on the modes of the SRDF Groups between two arrays. A legend is available under the view:

Edges that are drawn with short dashes and short gapes between the dashes indicate that all the SRDF Groups between the two Arrays are Metro or Synchronous SRDF Groups.

Edges that are drawn with longer dashes and a short gap between the dashes indicate that all the SRDF Groups between the two Arrays are Asynchronous.

Edges that are solid indicate that there is a mix of Asynchronous, Synchronous, and SRDF/Metro SRDF Groups between the two Arrays.

Edges that are drawn with short dashes and a long distance between the dashes indicate that the SRDF Groups between the two Arrays are Other SRDF Groups than mentioned above, including Empty SRDF Groups, Virtual Witness, Adaptive Copy, etc.

The nodes are drawn with some basic information about the array, including array ID and if set, the user-defined nice name of the Array. An icon specific to the model of the Array is also drawn into the node.

The Migrations Environments topology view visually describes the layout of the migration environments of the selected storage system.

The edges are color coded using the familiar traffic light system Red, Yellow, and Green, Red in this case meaning the Migration Environment is in an Invalid State and Green meaning it is in a valid state. The color of the edge can also be dictated by the worst state of any migrations using this Environment. The edges are all drawn in a solid full line.

The nodes are drawn with some basic information about the storage system, including ID and if set, the user-defined nice name of the storage system. An icon specific to the model of the Array is drawn into the node.

Recenter - this brings the topology views nodes and edges back into full view.

- Zoom the view in to see nodes and edges.

- zoom the view out to view more of the topology view.

- allows the user view a full screen view of the topology. Clicking this opens a message window that takes up most of the visible space on the screen. All functionality of this view is the same as the view embedded on the page.

Clicking displays a Layout Manager which provides layout change options.
