Hi,
The volume you have created is reserved for future provisioning actions from the WFA.
You can clean the reservations from the reservation screen ,or directly from the monitoring screen by clicking "Clean Reservation"
You can read more on reservations below
Reservations
You can use the OnCommand Workflow Automation resource reservation capability in workflows to
ensure that the required resources are available for successful execution of workflows.
The WFA commands have the capability to reserve the required resources and remove the
reservation after the resource is available in the WFA cache database, typically after a cache
- acquisition. The reservation capability ensures that the reserved resources are available for the
workflow until the reservation expiration period, which you have configured in the WFA
configuration settings.
You can use the reservation capability to exclude resources reserved by other workflows during
resource selection—for example, if a workflow that has reserved 100 GB of space on an aggregate is
scheduled for execution after a week, and you are executing another workflow that uses the Create
Volume command, the workflow that is executing does not take up the space reserved by the
scheduled workflow to create a new volume. In addition, the reservation capability enables
workflows to be executed in parallel.
When previewing a workflow for execution, the WFA planner considers all the reserved objects,
including the existing objects in the cache database. If you have enabled reservation, the effects of
the scheduled workflows and the workflows that are executing in parallel, and the existence of
storage elements are considered when planning the workflow. If a workflow fails because of
reservation created by another workflow and if you want to use the reserved objects for your current
workflow, you can clean the reservation made by the other workflow in the Monitoring window
