Host PowerTools automatically discovers Active-Active volumes during the volume query.
- Whenever Active-Active volume is discovered, a dedicated table with Active-Active related information ("Active-Active Volumes" table) will be available on volume listing.
- Active-Active volumes are marked on each system volume list.
- An Active-Active volume can be mapped to a host through one or both of the peers.
- Each mapped peer will appear in its system volumes list.
- If both peers are mapped, they will have the same specifications: Device (unique identifier), mount point and size.
- Number of paths are depended on the zoning to each of the systems.
- The LUN (ID) is depended on the mapping. It is recommended to map both peers with the same LUN.
- The volume name of each peer can be different.
"Active/Active Volumes" table
The "Active-Active Volumes" table provides the following information:
- The device name of the Active-Active volume. (unique identifier)
- Mount point. (if mounted)
- Information about each peer system, presented under "System A/B" columns.
- System name.
- LUN's paths ALUA state
- Number of paths to each system.
- "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.
- The ALUA state is not available on AIX operating system.
Querying via CLI
Active-Active volumes can be queried using the ‘Infinihost volume list’ command.
- Active-Active volumes are marked in each system volume list with a ‘**’ suffix on the volume's name.
- The "–detailed" argument can be used to present additional information such as LUN and the systems S/N.
Querying via GUI
Open the main screen.
- The "ACTIVE / ACTIVE Volumes" table appears whenever an Active-Active volume is discovered.
- When hovering over a system the LUN appears.
- Active-Active volumes are labeled with "ACTIVE/ACTIVE" in each system volume list.
