This section provides information and procedures to install software for the Sun Cluster module to Sun Management Center.
The Sun Cluster module for Sun Management Center enables you to use Sun Management Center to monitor the cluster. The following table lists the tasks to perform to install the Sun Cluster–module software for Sun Management Center.Table 2–6 Task Map: Installing the Sun Cluster Module for Sun Management Center
1. Install Sun Management Center server, help-server, agent, and console packages.
Sun Management Center documentation
2. Install Sun Cluster–module packages.
3. Start Sun Management Center server, console, and agent processes.
4. Add each cluster node as a Sun Management Center agent host object.
5. Load the Sun Cluster module to begin to monitor the cluster.
The Sun Cluster module for Sun Management Center is used to monitor a Sun Cluster configuration. Perform the following tasks before you install the Sun Cluster module packages.
Space requirements - Ensure that 25 Mbytes of space is available on each cluster node for Sun Cluster–module packages.
The following are additional requirements for a Sun Cluster configuration:
Install the Sun Management Center agent package on each cluster node.
When you install Sun Management Center on an agent machine (cluster node), choose whether to use the default of 161 for the agent (SNMP) communication port or another number. This port number enables the server to communicate with this agent. Record the port number that you choose for reference later when you configure the cluster nodes for monitoring.
See your Sun Management Center installation documentation for information about choosing an SNMP port number.
Install the Sun Management Center server, help–server, and console packages on noncluster nodes.
If you have an administrative console or other dedicated machine, you can run the console process on the administrative console and the server process on a separate machine. This installation approach improves Sun Management Center performance.
Web browser - Ensure that the web browser that you use to connect to Sun Management Center is supported by Sun Management Center. Certain features, such as online help, might not be available on unsupported web browsers. See your Sun Management Center documentation for information about supported web browsers and any configuration requirements.
Perform this procedure to install the Sun Cluster–module server and help–server packages.
The Sun Cluster–module agent packages, SUNWscsal and SUNWscsam, are already added to cluster nodes during Sun Cluster software installation.
Ensure that all Sun Management Center core packages are installed on the appropriate machines. This task includes installing Sun Management Center agent packages on each cluster node. See your Sun Management Center documentation for installation instructions.
On the server machine, install the Sun Cluster–module server package SUNWscssv.
Insert the Sun Cluster 2 of 2 CD-ROM for the SPARC platform in the CD-ROM drive.
If the volume management daemon vold(1M) is running and is configured to manage CD-ROM devices, the daemon automatically mounts the CD-ROM on the /cdrom/cdrom0/ directory.
Change to the Solaris_sparc/Product/sun_cluster/Solaris_ver/Packages/ directory, where ver is 8 for Solaris 8, 9 for Solaris 9, or 10 for Solaris 10.
# cd /cdrom/cdrom0/Solaris_sparc/Product/sun_cluster/Solaris_ver/Packages/
Install the Sun Cluster–module server package.
# pkgadd -d . SUNWscssv
Change to a directory that does not reside on the CD-ROM and eject the CD-ROM.
# eject cdrom
On the Sun Management Center 3.0 help-server machine or the Sun Management Center 3.5 server machine, install the Sun Cluster–module help–server package SUNWscshl.
Use the same procedure as in the previous step.
Install any Sun Cluster–module patches.
See Patches and Required Firmware Levels in Sun Cluster 3.1 8/05 Release Notes for Solaris OS for the location of patches and installation instructions.
Start Sun Management Center. Go to SPARC: How to Start Sun Management Center.
Perform this procedure to start the Sun Management Center server, agent, and console processes.
As superuser, on the Sun Management Center server machine, start the Sun Management Center server process.
The install-dir is the directory on which you installed the Sun Management Center software. The default directory is /opt.
# /install-dir/SUNWsymon/sbin/es-start -S
As superuser, on each Sun Management Center agent machine (cluster node), start the Sun Management Center agent process.
# /install-dir/SUNWsymon/sbin/es-start -a
On each Sun Management Center agent machine (cluster node), ensure that the scsymon_srv daemon is running.
# ps -ef | grep scsymon_srv
If any cluster node is not already running the scsymon_srv daemon, start the daemon on that node.
On the Sun Management Center console machine (administrative console), start the Sun Management Center console.
You do not need to be superuser to start the console process.
% /install-dir/SUNWsymon/sbin/es-start -c
Add a cluster node as a monitored host object. Go to SPARC: How to Add a Cluster Node as a Sun Management Center Agent Host Object.
Perform this procedure to create a Sun Management Center agent host object for a cluster node.
Log in to Sun Management Center.
See your Sun Management Center documentation.
From the Sun Management Center main window, select a domain from the Sun Management Center Administrative Domains pull-down list.
This domain contains the Sun Management Center agent host object that you create. During Sun Management Center software installation, a Default Domain was automatically created for you. You can use this domain, select another existing domain, or create a new domain.
See your Sun Management Center documentation for information about how to create Sun Management Center domains.
Choose Edit⇒Create an Object from the pull-down menu.
Click the Node tab.
From the Monitor Via pull-down list, select Sun Management Center Agent - Host.
Fill in the name of the cluster node, for example, phys-schost-1, in the Node Label and Hostname text fields.
Leave the IP text field blank. The Description text field is optional.
In the Port text field, type the port number that you chose when you installed the Sun Management Center agent machine.
A Sun Management Center agent host object is created in the domain.
Load the Sun Cluster module. Go to SPARC: How to Load the Sun Cluster Module.
You need only one cluster node host object to use Sun Cluster–module monitoring and configuration functions for the entire cluster. However, if that cluster node becomes unavailable, connection to the cluster through that host object also becomes unavailable. Then you need another cluster-node host object to reconnect to the cluster.
Perform this procedure to start cluster monitoring.
In the Sun Management Center main window, right click the icon of a cluster node.
The pull-down menu is displayed.
Choose Load Module.
The Load Module window lists each available Sun Management Center module and whether the module is currently loaded.
Choose Sun Cluster: Not Loaded and click OK.
The Module Loader window shows the current parameter information for the selected module.
After a few moments, the module is loaded. A Sun Cluster icon is then displayed in the Details window.
Verify that the Sun Cluster module is loaded.
Under the Operating System category, expand the Sun Cluster subtree in either of the following ways:
To view online help for a specific Sun Cluster module item, place the cursor over the item. Then click the right mouse button and select Help from the pop-up menu.
To access the home page for the Sun Cluster module online help, place the cursor over the Cluster Info icon. Then click the right mouse button and select Help from the pop-up menu.
To directly access the home page for the Sun Cluster module online help, click the Sun Management Center Help button to launch the help browser. Then go to the following URL, where install-dir is the directory on which you installed the Sun Management Center software:
The Help button in the Sun Management Center browser accesses online help for Sun Management Center, not the topics specific to the Sun Cluster module.
See Sun Management Center online help and your Sun Management Center documentation for information about how to use Sun Management Center.
Install third-party applications, register resource types, set up resource groups, and configure data services. See the documentation that is supplied with the application software and the Sun Cluster Data Services Planning and Administration Guide for Solaris OS.
