Installation Requirements for Sun Management Center Software for Sun Cluster Monitoring

The Sun Cluster module for the Sun Management Center product (formerly Sun Enterprise SyMON) is used to configure resource groups and monitor clusters. Perform the following tasks before installing 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 by running the console on the administrative console and the server 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 installing the Sun Management Center product 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 configuring the cluster for monitoring.

How to Install the Sun Cluster Module for Sun Management Center

Perform this procedure to install the Sun Cluster module console, 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 the Sun Management Center core packages are installed.

This step includes installing Sun Management Center agent packages on each cluster node. Refer to Sun Management Center documentation for installation instructions.

On the administrative console, install the Sun Cluster module console package.
1. Become superuser.
2. If you are installing from the CD-ROM, insert the Sun Cluster module CD-ROM into the CD-ROM drive.
3. Change to the /cdrom_image/SunCluster_3.0/Packages directory.
4. Install the Sun Cluster module console package.
  # pkgadd -d . SUNWscscn
5. If you installed from a CD-ROM, eject the CD-ROM.

On the server machine, install the Sun Cluster module server package SUNWscssv.

Use the same procedure as in Step 2.

On the help server machine, install the Sun Cluster module help server package SUNWscshl.

Use the same procedure as in Step 2.

Install any Sun Cluster module patches.

Refer to Sun Cluster 3.0 Release Notes for the location of patches and installation instructions.

Where to Go From Here

To start the Sun Management Center software, go to "How to Start Sun Management Center Software".

How to Start Sun Management Center Software

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 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.

Where to Go From Here

To 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 are creating. 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.

Refer to your Sun Management Center documentation for information about creating 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 during Sun Management Center agent installation.

Click OK.

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

Where to Go From Here

To 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, double-click the agent host object for a cluster node.

The agent host object is shown in two places. You can double-click either one. The Details window of the host object is then displayed.

Select the icon at the root (top) of the hierarchy to highlight it.

This icon is labeled with the cluster node name.

Select Module>Load Module from the pull-down menu.

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

Select Sun Cluster: Not loaded (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.

Refer to the Sun Cluster module online help for information about using 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.
