5 Troubleshooting

Introduction

The following information is designed to help resolve some common operating issues that might

occur when you use this management pack.

The troubleshooting issues are organized into the following categories:

• “Discovery issues” (page 24)

• “Authoring issues” (page 24)

• “Operational and usage issues” (page 25)

• “Device Monitor (DMC and DMS) operational and usage issues” (page 27)

Discovery issues

Operations Manager does not discover HP Linux servers

HP Linux servers must be registered with a DMS.

Use the DMC to review each monitored server state. If a red state appears on a server, resolve

the issue, and then update the server registration information.

The updated registration information appears immediately in the DMC, but the Operations Manager

discovery process does not occur immediately. The discovery results do not appear on the

Operations console until after the next discovery cycle. The default discovery interval is 14400

seconds (4 hours). For information about registering servers with a DMS, see the HP Device Monitor

for Microsoft System Center User Guide.

In addition to registering servers, you must perform the following actions:

• Ensure that a discovery cycle has completed since you registered the server.

• Examine all current active alerts, including active alerts related to instances of the DMS, in

the domain of Operations Manager. Resolve all active alert issues, and then close the Active

Alerts view.

• Examine the Operations Manager Log. Review the Error and Warning entries that can cause

issues with the system. Report these issues to Microsoft.

Authoring issues

The following section provides troubleshooting information for authoring issues with the Operations

Manager.

Adding custom information to HP Management Packs by adding a custom task to an

HP class and overriding a parameter to HP rules

Adding custom information such as company knowledge or custom tasks, and overriding rules to

HP Management Packs will create a dependency from the custom management pack to the HP

Management Packs. HP Management Packs are sealed and protected from any modification, so

the custom task is stored in an external management pack. HP recommends that you create a new

custom management pack to manage custom information specific to HP Management Packs, as

this will ease future upgrades and migration paths.
