HP Storage Essentials V5.1 User Guide Second Edition (Linux Release) (T4283-96056, November 2006)

Discovering Applications, Backup Servers and Hosts140
• Discovery Data Collection/Get Details takes some time. You might want to perform this process
when the network and the managed elements are not busy.
• During Get Details/Discovery Data Collection the topology in System Manager is recalculated.
While the topology is being recalculated, the loading of the user interface in Storage Essentials
may be slow. It may also take more time to log into the management server during a topology
recalculation.
• (Discovery from HP SE) To obtain a picture of device connectivity quickly, click the Get
Topology button on the Topology tab.
• When you do Discovery Data Collection/Get Details that includes an AIX host, the system log
displays three SCSI errors (2 FSCSI error and 1 FCS error) per IBM adapter port. You can ignore
these errors.
• You can quarantine elements to exclude them from Discovery Data Collection/Get Details. See
”Placing an Element in Quarantine” on page 108 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 an element during Discovery Data
Collection/Get Details 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 Discovery Data Collection/Get Details
table. These elements appear as missing until they are removed from quarantine. See ”Removing
an Element from Quarantine” on page 109 for information on how to remove an element from
quarantine.

To obtain details:
1. Select Options > Storage Essentials > Discovery > Run Discovery Data Collection.
2. Select the discovery group from which you want to Get Details/Discovery Data Collection. If you
are obtaining Get Details/Discovery Data Collection for hosts for the first time, make sure All
Discovery Groups is selected.
You can use discovery groups to break up getting Discovery Data Collection. For example,
instead of Discovery Data Collection for all of the elements, you could specify that the
management server gets the element details 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 ”Modifying the Properties of a Discovered Address” on page 95.
3. Click the Get Details button.
You can view the progress of gathering details by clicking Tasks & Logs > View Storage
Essentials Logs.
When the software completes getting all elements details, it displays GETTING ALL DETAILS
COMPLETED on the View Logs page.
