proxies that were used to discover the element, the element may reappear the next time you Get
Details/Discovery Data Collection.
For example, assume you want to delete Switch_A. Switch_B and Switch_C were used to discover
Switch_A. If you delete only Switch_B and Switch_A, Switch_A will most likely reappear when you
Get Details/Discovery Data Collection because it is still accessible by Switch_C.
You can delete an element within the following tools:
• System Manager or Chargeback Manager - Gives you the option of deleting just the element
or deleting the element and the elements that use the same switches and proxies for access.
• Discovery Step 2 (Topology) (Discovery from HP SE only) - Gives you the option of deleting
multiple elements at a time. You are not given a detailed list of other elements you must delete;
however, you can use the table on the Discovery screen to determine which switches and
proxies provided access.
Deleting an Element Using System Manager or Chargeback Manager
To delete an element using System Manager or Chargeback Manager:
1. Do one of the following:
• In System Manager - Right-click an element and select Delete Element from the
drop-down menu. Right-click an element and select Delete Element from the drop-down
menu.
If you are blocking pop-ups and you use the right-click menu to delete an element from
System Manager, the Delete window is blocked and you are unable to delete the element.
You must disable the popup blocker before you can delete the element.
• In Chargeback Manager - Click the button for the element you want to delete.
2. If the element has multiple access points, you are asked which want to delete. Do one of the
following:
• Delete the element and its access points. This option lists not only the switch you want to
delete, but also the other elements that use the same switches and proxies as the element
you want to delete. For example, assume you want to delete Switch_A. Switch_B was used
to discover Switch_A. Let's assume Switch_B is also the only path to Switch_D. If you delete
Switch_B, you will no longer have access to Switch_D. This option would list Switch_D as
one of the other elements that need to be deleted.
An access point is the intersection of the IP address and the provider that discovered the IP
address. A provider is software that is used to gather information about an element.
• Delete the element. The element may reappear the next time you obtain element details.
This is because not all switches and proxies connected to the element have not been
removed. For example, assume you want to delete Switch_A. Switch_B is connected to
Switch_A. If you do not delete Switch_B, the next time you obtain element details Switch_B
will most likely find Switch_A again.
3. Click OK.
4. Make sure the deleted element is not included in a scheduled automatic discovery task in HP
SIM. If a scheduled automatic discovery task includes the deleted element, SIM will rediscover
the deleted element again during the next discovery.
