Troubleshooting Network Administration Problems

This chapter provides information on resolving network administration problems with Solstice EM.

This chapter comprises the following topics:

• Section 4.1 Tools for Evaluating Your Network
• Section 4.2 Evaluating Network Failures

For detailed information on how to use Solstice EM to perform network administration tasks, see the Managing Your Network guide.

4.1 Tools for Evaluating Your Network

Most of the Solstice EM core tools help you monitor network status and respond to network events. In particular, the following tools provide specific information:

• Network Views--Provides a visual display of the managed objects in your network.
• Network Discovery--Allows you to find out what objects are visible in your network and to monitor communications among those objects.
• Event Logs--Allows you to keep a record of events that occur on your network.
• Alarms--Allows you to respond to events that occur on your network.
• Request Controllers --Allows you to identify events to respond to and default values for responding to those events.

For more information about using these Solstice EM tools, see the Managing Your Network guide.

4.2 Evaluating Network Failures

4.2.1 Solstice EM Cannot Discover Your Network

Problem: Network Discovery is running on your network, but finds nothing.

Solution: Use these steps to correct the problem.

• Your network connection might be down. Check the hardware and fix the problem, if needed.
• Verify that Network Discovery is functioning correctly by viewing its progress in the Network Discovery window.
• If you specify search parameters, such as specific devices or an IP range, ensure that they in fact exist on your network.
• Run Network Discovery from a command line using the debugging options discussed in Chapter 3 of the Managing Your Network guide.

4.2.2 Physical Network and Solstice EM Network Topology Inconsistent

Problem: The network physical configuration does not agree with what Solstice EM displays in the Network Views window.

Solutions: Try these procedures to correct the problem.

• To populate the MIS automatically, use Network Discovery, which finds hosts, routers, networks, links, and SNMP devices to manage. When Network Discovery finds one of these elements, it creates a record in the MIS for that element.
• Recent changes to the configuration might not be visible in Network Views yet. Try shutting down and restarting Network Views.
• The MIS database can also become corrupted. In this case, manually remove objects that appear to be incorrect and run a new discovery. Or, use the following command to discover a specific device:
  /opt/SUNWconn/bin/emdiscover -device device_name

4.2.3 Configured Events Do Not Appear

Problem: Particular events have been configured, but when the events occur, Solstice EM does not display them.

Probable Cause: You have not defined the event forwarding discriminators (EFDs) appropriately.

Solution: Use the MIS Connections tool to specify event forwarding discriminators. The on-line help accessed through the MIS Connections tool includes help about EFDs and CMIS filters.
