What’s in this Version |

Version A.03.00.01 is a minor update of ServiceGuard Manager. It has the same functionality as version A.03.00 (see below). The only change is that it now supports ServiceGuard 11.15 and SuSE Linux. (SuSE is available only in English.) In this document, information about A.03.00 also applies A.03.00.01, unless specifically noted. To see what version you have, go to the Help menu and select “About.” ServiceGuard Manager, versions A.03.00 and A.03.00.01, can be installed on HP-UX, Linux, and Windows. All platforms are available from the web at software.hp.com, or are delivered on CD ROM:
Now, ServiceGuard Manager interface is now available in 5 languages:
With version A.03.00 and later, you can see clusters on more than one subnet. One instance of ServiceGuard Manager can display several sessions, where each session represents a connection to a Cluster Object Manager. Hewlett-Packard supports up to 10 connected sessions in one instance of ServiceGuard Manager. One new property sheet shows information about all sessions in the map. Also, each session now has its own property sheet. With version A.03.00 and later, an Alerts icon on the toolbar can show you the most critical problem in all the cluster objects on the map, whether they are visible at the moment or not. Click the Alerts icon, and you see a window with a table of all alerts, problems with clusters, nodes, and packages. These are gathered and updated by ServiceGuard Manager each time it refreshes. In the Alerts window, you can filter and order the messages for help in troubleshooting. Performance has improved again. With version A.03.00 and later, problems with ServiceGuard Manager are presented as they occur, and no longer silently added to log files. When you see an error window, click the “details” button to see the log messages. You will see directions there telling you how to report the problem. ServiceControl Manager Version 3.0 now launches ServiceGuard Manager A.03.00 or later, with for ServiceControl Manager.) OVO 7.0 now integrates ServiceGuard Manager A.03.00 and later. Accessibility has been improved. See the “Accessibility” topic in the Help Table of Contents, under “Using ServiceGuard Manager.” The figure below shows an instance of ServiceGuard Manager with three sessions. The icon by the connection to COM mango shows that the user’s role is view-only for those clusters. In the first and last sessions, an icon shows the user can do administrative commands. The Alerts button tells you there is information about serious alerts. We can see some red-bordered clusters that are down. Also critical are the clusters that have a package icon with a red cross, showing they have packages that are down. With ServiceGuard Manager, you see your ServiceGuard clusters three ways.
You can save a record of your clusters. For example, you could document a newly configured cluster. If that cluster has problems later, you could easily compare the original and current states. Launch two instances of ServiceGuard Manager. Open the saved file in one, and connect “live” in the other. You can navigate both maps, and open equivalent property sheets for comparisons. Messages in the Events Browser are not saved in.sgm files. The following screenshot shows one of the clusters in Fig. 1.1. The session was saved as screenshotNoir.sgm. When opened, the user navigated to the star cluster for this view. This is a saved view of the cluster Star, seen in Fig 1.1. You can see the no-failover alert on the cluster refers to pkg2. Details about the cluster lock alert are in the Cluster Properties in the Quorum Server tab. The red Alerts button on the toolbar tells you that there is a serious problem in some cluster. Even though you don’t see that cluster now, you could click Alerts and get information about it from the Alerts window. You install ServiceGuard Manager on a management station. This can be HP-UX, Linux, or Windows. From the management station, you connect to a server with COM (Cluster Object Manager) software on a ServiceGuard node (HP-UX or Linux). (The COM is installed as a part of ServiceGuard.) Each server connection is displayed on the interface as a session. You tell the COM server to go out on its subnets, and discover ServiceGuard nodes configured for these types of clusters:
If you use a valid logon and password for a COM server with ServiceGuard A.11.12 or later, you get viewing permission. To do administrative commands, you must log in as root on an HP-UX server with ServiceGuard A.11.14 or later and Cluster Object Manager Version A.01.03.01 or later. (See "Required and Recommended Patches” in this document.) The server queries ServiceGuard nodes on its subnet for status and configuration information. If the server has access permissions, the cluster node will supply the information. (See “Before Installing ServiceGuard Manager,” below, for a description of configuring node access permissions with cmclnodelist.) This information is used for the map, tree, and properties. Any status alerts are posted in the Alerts window. Note: Because Continental Clusters are always on more than one subnet, ServiceGuard Manager sees them as two clusters. To see all the information about a Continental cluster, open two separate sessions, connecting to a COM server on each subnet. These Release Notes will help you install ServiceGuard Manager. Once ServiceGuard Manager is running, online help has the information about how to use the interface.
