The software obtains just enough information about where the element is connected in the
topology, for example a switch connected to a host.
Step C — Run Discovery Data Collection
Obtain detailed information from the discovered applications as described in this section.
Keep in mind the following:
• Discovery Data Collection takes some time. You might want to perform this process when the
network and the managed elements are not busy.
• During Discovery Data Collection the topology is recalculated. While the topology is being
recalculated, the loading of the user interface may be slow. It may also take more time to log
into the management server during a topology recalculation.
• When you do Discovery Data Collection that includes an AIX host, three SCSI errors (2 FSCSI
error and 1 FCS error) per IBM adapter port are displayed in the system log. You can ignore
these errors.
• You can quarantine elements to exclude them from Discovery Data Collection. See ”Placing an
Element in Quarantine” on page 167 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 is unable to obtain information from an element during Discovery
Data Collection as a result of a CIM extension failure, 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 Discovery Data Collection table. These elements
appear as missing until they are removed from quarantine. See ”Removing an Element from
Quarantine” on page 167 for information on how to remove an element from quarantine.
