The initial map view

When you launch a storage view map, the initial view shows the entire map. All healthy virtual volumes are shown collapsed (no connecting line to supporting devices). Virtual volumes with an Operational status other than OK are shown expanded (showing connecting line to supporting devices) and are colored red or yellow, depending on the severity of the status. Identifying unhealthy storage objects in a map provides more information on the use of color to indicate unhealthy storage objects.

Storage view maps can be very large depending on the number of objects in the view. To help you navigate the map, there is a map overview area in the upper portion of the panel that allows you to pan and zoom using a birds-eye view of the map. Under the Map Overview is a section that lists the storage objects in the storage view. Expanding a list and selecting an object from this list will cause the map to zoom and pan to the selected object.

After zooming in or out of specific areas of the map, you can click to refresh the map and reset it to the initial view.

Storage view components

The components of the storage view (initiators, ports and virtual volumes) are shown at the bottom of the left panel. Click a tab (Initiators, Ports, or Virtual Volumes) to see a list of those objects in the view, and the operational status of each object. You can expand volumes to show their underlying objects such as supporting device, extent, storage volume, and storage array.

You can also click an object name in the panel on the left to automatically locate and highlight the object in the map. To resize the panel, click and drag the right edge of the panel.

Expanding or collapsing a virtual volume

Each virtual volume box in a map contains icons that allow you to instantly expand or collapse the virtual volume. When you expand a virtual volume, the map shows the underlying supporting devices, down to the array level. When you collapse a virtual volume, no supporting devices display for the virtual volume.

Expand or collapse virtual volumes in the following ways:

• A single virtual volume — Click or in a virtual volume box to expand or collapse the virtual volume. If you reset the map with a virtual volume expanded or collapsed, the initial map view zooms in on the expanded or collapsed virtual volume. Expanded virtual volumes are repositioned at the bottom of the virtual volumes area of the map.
• All virtual volumes — Click or in the map title bar to expand or collapse all virtual volumes in the map. This operation may take several minutes, depending on the number of virtual volumes in the storage view. If a storage view contains more than 50 virtual volumes, is disabled.
