Deleting Fabrics
When you delete a fabric, the elements in the fabric are not removed. After you delete the fabric,
the management server recalculates the entire topology. The recalculation may take some time,
especially if you have a large topology.
To delete a fabric:
1. Access System Manager (Tools > Storage Essentials > System Manager in HP Systems
Insight Manager).
2. Click the List tab.
3. Right-click a fabric name.
4. Select the Delete This Fabric option from the drop-down menu.
5. When you are asked if you want to delete the fabric, click Yes.
The management server recalculates the topology. If the elements in the deleted fabric do not
belong to another fabric, they are moved to the unknown node on the List tab.

About Hiding Generic Hosts
You can reduce the amount of time it takes to arrange your topology, by using the hide unnamed
generic hosts feature to hide hosts that a switch has detected. An element is considered to be
generic if the management server can detect the element but it cannot obtain additional information
about the element during Getting the Topology or Discovery Data Collection/Get Details.
When you use the show/hide feature, your changes persist to the next time you log into the
management server. If you log in as another user, you will not see your changes. This feature allows
each user to arrange the topology as he or she wishes.
NOTE: This feature only pertains to unnamed generic hosts. If you name a generic host, you
cannot use this feature to hide the named host. The hide generic element feature also does not work
for grouped unnamed generic hosts and missing elements. To learn how to give a custom name to
an unnamed generic host, see ” Assigning a Custom Name ” on page 277. To learn more about
groups, see the topic, ” About Groups ” on page 252.
The management server provides two variations of this feature:
• Hiding Generic Hosts: This feature hides unnamed generic hosts detected by a switch. The
management server detects an element by looking at the ports on a switch. If it cannot find
