Assigning a block host to a volume enables the host to discover the volume. Assignments are managed by a mapping of hosts to volumes on the same tenant.
Managing Host-Volume Mappings in the VAST Web UI
To manage the mapping of hosts to a volume:
In the Volumes tab, right-click the volume and select Manage Mappings.
Details of block hosts are listed. Hosts that are already mapped to the volume are selected.
Select any hosts that you want to assign to the volume. Deselect any hosts that you want to unmap from the volume.
Click Save Mapping.
The mapping task begins and you can track it in the Activities page.
When the mapping is complete, you can see:
which hosts are assigned to a volume in the Assigned Hosts column of the Volumes tab.
which volumes are assigned to a host in the Assigned Volumes column of the Hosts tab.
