Volumes Mapping Table page in the Hosts view
The Volumes Mapping Table page in the Hosts view enables you to control which host has access to which volume.
To access the page, in the Helix Continuous Optimization Dashboard, click Capacity > Storage > Hosts, and in the Hosts view page, click the Volumes Mapping Table tab.
Metrics per host are displayed in a tabular format.
By default, some columns are hidden. You can show or hide columns using the action menu
that is located next to the table title.
Each row in the table represents a host and displays the following metrics, which are used to compute the metrics available in the Hosts, Hosts to Systems, Hosts to Pools, and Hosts to Volumes pages.
Host-related metrics are not available when the option Disabled and Collected for metric computation (Default) are selected in the ETL additional settings. Refer to Customizing Volumes and Shares Monitoring for more information.
