Installation Requirements for Sun Cluster Monitoring

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.
Sun Management Center packages – You must install the Sun Management Center server, help server, and console packages on non-cluster nodes. If you have an administrative console or other dedicated machine, you can realize improved performance if you run the console process on the administrative console and the server process on a separate machine. You must install the Sun Management Center agent package on each cluster node.

Follow procedures in the Sun Management Center documentation to install the Sun Management Center packages.
Simple Network Management Protocol (SNMP) port – When you install Sun Management Center on the agent, 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 you choose for reference later when you configure the cluster for monitoring.

How to Install the Sun Cluster Module for Sun Management Center

Perform this procedure to install the Sun Cluster module server and help server packages.

Note –

The Sun Cluster module agent packages (SUNWscsal and SUNWscsam) were added to cluster nodes during Sun Cluster software installation.

Ensure that all Sun Management Center core packages are installed on the appropriate machines.

This step 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.
1. Become superuser.
2. Insert the Sun Cluster 3.1 CD-ROM into the CD-ROM drive.
3. Change to the /cdrom/suncluster_3_1/SunCluster_3.1/Sol_ver/Packages directory, where ver is 8 (for Solaris 8) or 9 (for Solaris 9) .
  
  The following example uses the path to the Solaris 8 version of Sun Cluster software.
  # cd /cdrom/suncluster_3_1/SunCluster_3.1/Sol_8/Packages
4. Install the Sun Cluster module server package.
  # pkgadd -d . SUNWscssv
5. Change to the CD-ROM root directory and eject the CD-ROM.

On the help 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 the Sun Cluster 3.1 Release Notes for the location of patches and installation instructions.

Start Sun Management Center.

Go to How to Start Sun Management Center.

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.
# /opt/SUNWsymon/sbin/es-start -S

As superuser, on each Sun Management Center agent machine (cluster node), start the Sun Management Center agent process.
# /opt/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.
# /usr/cluster/lib/scsymon/scsymon_srv

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.
% /opt/SUNWsymon/sbin/es-start -c

Type your login name, password, and server hostname and click Login.

Add cluster nodes as monitored host objects.

Go to How to Add a Cluster Node as a Sun Management Center Agent Host Object.

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.

Note –

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.

From the Sun Management Center main window, select a domain from the Sun Management Center Administrative Domains pull-down list.

This domain will contain the Sun Management Center agent host object 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 one.

See your Sun Management Center documentation for information about how to create Sun Management Center domains.

Select Edit>Create an Object from the pull-down menu.

Select 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 you chose when you installed the Sun Management Center agent.

Click OK.

A Sun Management Center agent host object is created in the domain.

Load the Sun Cluster module.

Go to How to Load the Sun Cluster Module.

How to Load the Sun Cluster Module

Perform this procedure to start cluster monitoring.

From the Sun Management Center main window, point to an icon of a cluster node, right-click to display the pull-down menu, and select Load Module.

The Load Module window lists each available Sun Management Center module and whether it is currently loaded.

Select Sun Cluster: Not loaded, which is usually at the bottom of the list, and click OK.

The Module Loader window shows the current parameter information for the selected module.

Click OK.

After a few moments the module is loaded and a Sun Cluster icon is displayed in the Details window.

In the Details window under the Operating System category, expand the Sun Cluster subtree in either of the following ways.
- In the tree hierarchy on the left side of the window, place the cursor over the Sun Cluster module icon and single-click the left mouse button.
- In the topology view on the right side of the window, place the cursor over the Sun Cluster module icon and double-click the left mouse button.

See the Sun Cluster module online help for information about how to use Sun Cluster module features.
- To view online help for a specific Sun Cluster module item, place the cursor over the item, 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, 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 URL file:/opt/SUNWsymon/lib/locale/C/help/main.top.html.
Note –
The Help button in the Sun Management Center browser accesses Sun Management Center online help, not 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 supplied with the application software and the Sun Cluster 3.1 Data Service Planning and Administration Guide.
