Discovering Filers, Tape Libraries, Switches and Storage Systems90
IMPORTANT: You must perform this step to view elements connected in the topology.
To obtain enough information to display the topology in System Manager:
1. Click the Discovery menu in the upper-right corner of the Store Essentials home page.
2. Click Topology in the upper-right corner.
The discovered elements are selected.
3. Select the File Server SRM option corresponding to host file systems you want to monitor. The File
Server SRM option appears for the hosts that have the CIM Extension and support file SRM.
4. Select the discovery group from which you want to obtain the topology. If you are obtaining the
topology for the first time, make sure All Discovery Groups is selected.
You can use discovery groups to break up getting the topology or getting details. For example,
instead of getting the topology for all of the discovered elements, you could specify that the
management server gets the topology 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 90.
5. Click the Get Topology button.
The management server obtains the topology for selected elements.
The management server displays the Log Message page. After the management server builds
the topology, a link appears to take you to System Manager so you can verify the topology view.
You can also access System Manager by clicking System Manager in the left pane.
6. If you see errors in the topology, look at the log messages, which can provide an indication of
what went wrong. See the topic, ”Viewing Log Messages” on page 66 for more information
about the messages that appear in this tab. Look at Event Manager for additional information.
Access Event Managerby clicking the Event Manager button in the left pane. To obtain
troubleshooting information, see the topic, ”Troubleshooting Topology Issues” on page 263.
If the topology for an element in your network changes, select the element and click Get
Topology (Tools > Storage Essentials > Home > Discovery > Topology) to updated the
information.
The software obtains just enough information about where the element is connected in the
topology, for example a switch connected to a host.
7. See the topics in ”Troubleshooting” on page 247 for more information on troubleshooting
problems with discovery and building the topology.
Modifying the Properties of a Discovered Address
All elements are initially placed in the Default discovery group. You can then move elements from
the Default discovery group to other discovery groups.You can use discovery groups to break up
Get Details/Discovery Data Collection. For example, you could specify that the management server
get Get Details/Discovery Data Collection for only the elements in Discovery Group 1, thus, saving
you time. This feature is sometimes referred to as segmented replication because you can specify
getting Get Details/Discovery Data Collection for a segment of the discovered elements.
