This section provides information and procedures to install software for the Oracle Solaris Cluster module to Sun Management Center.
The Oracle Solaris 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 Oracle Solaris Cluster–module software for Sun Management Center. Complete the procedures in the order that is indicated.
Table 8-1 Task Map: Installing the Oracle Solaris Cluster Module for Sun Management Center
The Oracle Solaris Cluster module for Sun Management Center is used to monitor an Oracle Solaris Cluster configuration. Perform the following tasks before you install the Oracle Solaris Cluster module packages.
Space requirements – Ensure that 25 Mbytes of space is available on each cluster node for Oracle Solaris Cluster–module packages.
The following are additional requirements for an Oracle Solaris 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.
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.
For best results, install the Sun Management Center server and console packages on noncluster machines.
If you choose to install the server or console packages on a cluster node, you might experience the following adverse performance impacts:
Cluster performance might be noticeably slowed due to the increased load from Sun Management Center processes. This is especially likely when the Sun Management Center server runs on a cluster node.
Sun Management Center is not made highly available when you install the server on a cluster node. Sun Management Center service will fail if the node goes down, such as during a failover to another node.
Web browser – Ensure that the web browser that you use to connect to Sun Management Center is supported by Sun Management Center. Certain features 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 Oracle Solaris Cluster–module server package.
Note - The Oracle Solaris Cluster-module agent packages, SUNWscsal and SUNWscsam, are already added to global-cluster nodes during Oracle Solaris Cluster software installation.
Before You Begin
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.
If the volume management daemon vold(1M) is running and is configured to manage CD-ROM or DVD devices, the daemon automatically mounts the media on the /cdrom/cdrom0 directory.
phys-schost# cd /cdrom/cdrom0/Solaris_sparc/Product/sun_cluster/Solaris_ver/Packages/
phys-schost# pkgadd -d . SUNWscssv
phys-schost# eject cdrom
See Patches and Required Firmware Levels in Sun Cluster Release Notes 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.
The install-dir is the directory on which you installed the Sun Management Center software. The default directory is /opt.
server# /install-dir/SUNWsymon/sbin/es-start -S
phys-schost# /install-dir/SUNWsymon/sbin/es-start -a
phys-schost# ps -ef | grep scsymon_srv
If any cluster node is not already running the scsymon_srv daemon, start the daemon on that node.
You do not need to be superuser to start the console process.
adminconsole% /install-dir/SUNWsymon/sbin/es-start -c
Add a cluster node as a monitored host object. Go to SPARC: How to Add a Global-Cluster Node as a Sun Management Center Agent Host Object.
Perform this procedure to create a Sun Management Center agent host object for a global-cluster node.
See your Sun Management Center documentation.
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.
Leave the IP text field blank. The Description text field is optional.
A Sun Management Center agent host object is created in the domain.
Load the Oracle Solaris Cluster module. Go to SPARC: How to Load the Oracle Solaris Cluster Module.
You need only one cluster node host object to use Oracle Solaris 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.
The pull-down menu is displayed.
The Load Module window lists each available Sun Management Center module and whether the module is currently loaded.
The Module Loader window shows the current parameter information for the selected module.
After a few moments, the module is loaded. An Oracle Solaris Cluster icon is then displayed in the Details window.
Under the Operating System category, expand the Oracle Solaris Cluster subtree in either of the following ways:
See 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 Oracle Solaris Cluster Data Services Planning and Administration Guide.
