Filtering the view
Use the filters on the tab to narrow the hierarchy when the appliance has more storage or more instances than you want to look at in one view. You can filter by the following:
Enclosure - Limits the view to the enclosures that you select.
Instance - Limits the view to the volumes that belong to the instances that you select. Use this filter to see every LUN that a single instance draws on.
Volume - Limits the view to the volumes that you select.
