SPARC: Installation Requirements for Oracle Solaris Cluster Monitoring

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.

• Sun Management Center installation – Follow procedures in your Sun Management Center installation documentation to install Sun Management Center software.

  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.

SPARC: How to Install the Oracle Solaris Cluster Module for Sun Management Center

Perform this procedure to install the Oracle Solaris Cluster–module server package.

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.

1. On the Sun Management Center server machine, install the Oracle Solaris Cluster–module server package SUNWscssv.
   1. Become superuser.
   2. Load the DVD-ROM into the DVD-ROM drive.

      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.

   3. Change to the Solaris_sparc/Product/sun_cluster/Solaris_ver/Packages/ directory, where ver is 10 for Solaris 10.

      phys-schost# cd /cdrom/cdrom0/Solaris_sparc/Product/sun_cluster/Solaris_ver/Packages/

   4. Install the Oracle Solaris Cluster–module server package.

      phys-schost# pkgadd -d . SUNWscssv

   5. Unload the DVD-ROM from the DVD-ROM drive.
      1. To ensure that the DVD-ROM is not being used, change to a directory that does not reside on the DVD-ROM.
      2. Eject the DVD-ROM.

         phys-schost# eject cdrom

2. Install any Oracle Solaris Cluster–module patches.

   See Patches and Required Firmware Levels in Oracle Solaris Cluster 3.3 5/11 Release Notes for the location of patches and installation instructions.

Next Steps

Start Sun Management Center. Go to SPARC: How to Start Sun Management Center.

SPARC: How to Start Sun Management Center

Perform this procedure to start the Sun Management Center server, agent, and console processes.

1. 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.

   server# /install-dir/SUNWsymon/sbin/es-start -S

2. As superuser, on each Sun Management Center agent machine (cluster node), start the Sun Management Center agent process.

   phys-schost# /install-dir/SUNWsymon/sbin/es-start -a

3. On each Sun Management Center agent machine (cluster node), ensure that the scsymon_srv daemon is running.

   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.

   phys-schost# /usr/cluster/lib/scsymon/scsymon_srv

4. 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.

   adminconsole% /install-dir/SUNWsymon/sbin/es-start -c

Next Steps

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.

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.

1. Log in to Sun Management Center.

   See your Sun Management Center documentation.

2. 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.

3. Choose Edit⇒Create an Object from the pull-down menu.
4. Click the Node tab.
5. From the Monitor Via pull-down list, select Sun Management Center Agent - Host.
6. 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.

7. In the Port text field, type the port number that you chose when you installed the Sun Management Center agent machine.
8. Click OK.

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

Next Steps

Load the Oracle Solaris Cluster module. Go to SPARC: How to Load the Oracle Solaris Cluster Module.

Troubleshooting

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.

SPARC: How to Load the Oracle Solaris Cluster Module

Perform this procedure to start cluster monitoring.

1. In the Sun Management Center main window, right click the icon of a cluster node.

   The pull-down menu is displayed.

2. Choose Load Module.

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

3. Choose Oracle Solaris Cluster: Not Loaded and click OK.

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

4. Click OK.

   After a few moments, the module is loaded. An Oracle Solaris Cluster icon is then displayed in the Details window.

5. Verify that the Oracle Solaris Cluster module is loaded.

   Under the Operating System category, expand the Oracle Solaris Cluster subtree in either of the following ways:

   • In the tree hierarchy on the left side of the window, place the cursor over the Oracle Solaris 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 Oracle Solaris Cluster module icon and double-click the left mouse button.
