Configuration scenarios

Figure: A logical domain resource depends on storage and network resources shows the basic dependencies for an logical domain resource.

Network configuration

Use the NIC agent to monitor the primary network interface, whether it is virtual or physical. Use the interface that appears using the ifconfig command.

Recommended network device to monitor.

Figure: The logical domain resource can depend on resources such as NIC, Volume, and DiskGroup depending on the environment is an example of an logical domain service group. The logical domain resource requires both network (NIC) and storage (Volume and DiskGroup) resources.

See the Veritas Cluster Server Bundled Agents Reference Guide for more information about the NIC agent.

Storage configurations

Depending on your storage configuration, use a combination of the Volume, DiskGroup, and Mount agents to monitor storage for logical domains.

Note:

Symantec recommends volumes or flat files in volumes that are managed by VxVM for LDom storage for configurations where VCS is in control domain.

Veritas Volume Manager exposed volumes

Veritas Volume Manager (VxVM) exposed volumes is the recommended storage solution for VCS in a control domain configuration. Use the Volume and DiskGroup agents to monitor a VxVM volume. VCS with VxVM provides superior protection for your highly available applications.

For more information about the Volume and DiskGroup agents, refer to the Veritas Cluster Server Bundled Agents Reference Guide.

Image files

Use the Mount, Volume, and DiskGroup agents to monitor an image file.

Configuring logical domain

You must perform the following steps to configure logical domain.

To configure logical domain

  1. Make sure that the network and storage setup meet the VCS requirements.

    See Veritas Cluster Server requirements.

  2. Make sure that you have installed the required Solaris operating system in the logical domain.
  3. Create logical domain (ldom1) on each system with an identical configuration and boot device.
Installing Veritas Cluster Server inside the control domain

You must install VCS in the control domain of each system.

To install Veritas Cluster Server inside the control domain

  • Install and configure VCS in the control domain of each system.

The process for installing VCS in the control domain is very similar to the regular installation of VCS. However, you must specify the host name of the control domain for the name of the host where you want to install VCS.

See the Veritas Cluster Server Installation Guide for VCS installation and configuration instructions.
