Host PowerTools for VMware automatically discovers Active-Active volumes and datastores.  

  • Whenever Active-Active volume is discovered, a dedicated table with Active-Active related information ("Active/Active Volumes" table) will appear at the top of the INFINIDAT view at the hosts and cluster vSphere objects. 
    • Active-Active volumes are marked on each system volume list.
      • Both Active-Active peers can appear on the volume list of each system. (in case both peers are mapped)
    • A pair of Active-Active volumes (both peers) will have the same device name and mount point.

Note

An Active-Active volume can be mapped to a host through one or both of the peers

  • Each mapped peer will appear also in its system volumes list. 
  • If both peers are mapped, they will have the same specifications: Device name, datastore and size.
    • Number of paths are depended on the connection to each of the systems.
    • LUN (ID) is depended on the mapping. It is recommended to map both peers with the same LUN.
    • The volume name of the peer can be different between the systems. 

"Active/Active Volumes" table

The "Active-Active Volumes" table provides the following information:

  • The device name.
  • Datastore name (if created).
  • Information about each peer system, presented under "System A/B" columns.
    • System name.
      • When hovering, the LUN ID appears.
    • LUN's paths ALUA state.
    • Number of paths to each system.

Note

  • "System A" column will present the system with the lower S/N.
    • If only one peer is mapped, it will be presented on the "System A" column.
  • Complete information is available only for mapped peers. 
  • Number of paths to each system and LUN ID information is available only with the host object view. 

Viewing Active-Active volumes and datastores

  1. In vSphere Web client select the desired host or cluster.

  2. Locate the INFINIDAT view. Follow the instructions here: Locating the INFINIDAT view.
  3. Main screen appears.
