•Get Details/Discovery Data Collection takes some time. You might want to perform this process when the network and the managed elements are not busy. (Discovery from HP SE only)To obtain a picture of device connectivity quickly, click the Get Topology button on the Topology tab.
•If you have problems obtaining information from Connectrix and McDATA switches during Get Details/Discovery Data Collection, see the topic, ”Step 2 - Discover Storage Systems, Filers and Tape Libraries” on page 53.
•You can use discovery groups to break up getting the topology (Discovery from HP SE only) or Get Details/Discovery Data Collection. For example, instead of Get Details/Discovery Data Collection for all of the elements, you could specify that the management server Get Details/Discovery Data Collection for only the elements in Discovery Group 1, thus, saving you time. You add an element to a discovery group by modifying the properties used to discover the element. See ”Moving Elements to Another Discovery Group” on page 88 for information on how to move one or more multiple elements to a discovery group. You can also move an element to another discovery group when you modify its discovery properties. See ”Modifying the Properties of a Discovered Address” on page 76.
•When an element in a given discovery group is updated, its dependent elements are also updated. For example, assume Host_A is the only element in Discovery Group 1. Host_A is connected through a switch and storage system. When you Get Details/Discovery Data Collection for Discovery Group 1, you also obtain details from the switch and storage system.
•You can quarantine elements to exclude them from Get Details/Discovery Data Collection. See ”Placing an Element in Quarantine” on page 89 for more information. Let us assume you want to discover all the elements in a discovery group, except for one. Perhaps the element you want to quarantine is being taken off the network for maintenance. You can use the quarantine feature to exclude one or more elements from discovery.

•If the management server unable to obtain information from a UNIX host during Get Details/Discovery Data Collection as a result of a CIM Extension hanging, the management server places the access point where the CIM Extension is located in quarantine. The management server then moves onto getting details for the next element in the Get Details/Discovery Data Collection table. These UNIX hosts appear as missing until they are removed from quarantine. See ”Removing an Element from Quarantine” on page 89 for information on how to remove an element from quarantine.
