Deleting a Node
After Discovery, the nodes in your network are known to SGM and added to the
SGM database. Physically deleting nodes from your network is not the same as
deleting them from the SGM database. The following sections describe the
differences between deleting nodes from your network, from the SGM database,
and from the SGM Discovery database, and the procedures for doing so:
•Deleting a Node from Your Network, page3-130
•Deleting a Node from the SGM Database, page 3-130
•Deleting a Node from the SGM Discovery Database, page 3-132

Deleting a Node from Your Network

If you physically delete a known node from your network (for example, by
powering down an ITP), it remains in the SGM database, SGM labels it
Unknown, and it is the system administrator’s responsibility to delete it from the
SGM database, if you choose to do so. SGM also labels all associated linksets and
links Unknown because SGM attempts to poll the node and gets no response.

Deleting a Node from the SGM Database

Typically, you delete a node from the SGM database for one of the following
reasons:
•You have physically deleted the node from your network. This is the most
common reason for deleting a node from the SGM database.
•The node is Unknown or Unmanaged, you are aware of the reason, and you
no longer want to see it in SGM displays. For example, the node might be a
test lab device.
•If you delete all linksets to an Unmanaged node, SGM does not
automatically delete the node. Instead, you must manually delete the node.
If you have physically deleted a known node from your network, and you then
delete it from SGM, it is no longer in the SGM database, it does not appear in
SGM windows, and it is not discovered when you run Discovery.
