Dell PowerStore Configuring Volumes

Volume and volume group topology

PowerStore enables you to see a graphical display of your block storage topology. This topology displays volumes, volume groups, clones, snapshots, and snapshot containers, enabling you to see the specific relationships among the storage objects in your environment.

The topology is initially shown in a tree-like layout. You can expand and collapse each object to view details about the object and its relationship to other objects in the storage environment. These changes are saved to user preferences and can be reverted to the default display by clicking Reset.

As new objects are added, you can click the Refresh Topology button, represented by the curved arrow icon, to see the updated topology.

Using the View Topology function, you can perform the following actions:

  • Collapse or expand the view of the topology.
  • Display the members of a volume group.
  • Change the topology by dragging objects to the place you choose.
  • Search for storage objects by name.
  • Display information about volumes, volume groups, and clones:
    • Details: Shows the type, family ID, storage protocol used, and so on
    • Capacity: Shows the amount of space that is provisioned locally, the amount of space provisioned for the family, and so on
    • Mapped hosts: Shows all hosts to which the storage object is mapped
  • Display information about the snapshots and snapshot containers that are associated with each storage object.
    NOTE:Scheduled snapshots do not appear in the topology view unless they are used to create clones.
