56Storage Foundation and High Availability Solutions support for Solaris ProjectsAbout VCS support for Solaris projectsAbout VCS support for Solaris projectsVCS provides application management and high availability to applications thatrun in Solaris projects.Overview of how VCS works with Solaris projectsYou can use VCS to perform the following:■■Start, stop, monitor, and fail over a Solaris project.Start, stop, monitor, and fail over an application that runs inside a Solarisproject.How VCS models containersVCS and necessary agents run in the global zone. For the applications that run ina Solaris project, the agents can run online entry point inside the project. If anyresource faults, VCS fails over the service group.Installing and configuring projects in a VCS environmentInstall and configure the project. Create the service group with the standardapplication resource types (application, storage, networking) and the Projectresource. VCS manages the project as a resource. You then configure the servicegroup’s ContainerInfo attribute.Configuring the ContainerInfo attributeThe service group attribute ContainerInfo specifies information about the Solarisproject. When you have configured and enabled the ContainerInfo attribute, youhave enabled the project-aware resources in that service group to work in theproject environment. VCS defines the project information at the level of the servicegroup so that you do not have to define it for each resource. You need to specifya per-system value for the ContainerInfo attribute.About the ContainerInfo service group attributeThe ContainerInfo attribute has the Name key, Type key, and Enabled key. TheName key defines the name of the container. The Type key lets you select the typeof container that you plan to use. The Enabled key enables the Project-awareresources within the service group. The ContainerInfo attribute specifies if youcan use the service group with the container.Assign the following values to the ContainerInfo attribute:
Storage Foundation and High Availability Solutions support for Solaris ProjectsAbout VCS support for Solaris projects57■■■NameThe name of the container.TypeThe type of container. You can set this to Project.EnabledSpecify the value as 0, if you want to disable the container. Specify the valueas 1, if you want to enable the container. Specify the value as 2, to enablephysical to virtual and virtual to physical failovers. When the value is 2, theProject resource mimics a non-existent entity.You can set a per-system value for this attribute.About the ContainerOpts resource type attributeThe ContainerOpts resource attribute is pre-set for project-aware resource types.It determines the following:■■Whether the project-aware resource can run in the project.Whether the container information that is defined in the service group’sContainerInfo attribute is passed to the resource.These values are only effective when you configure the ContainerInfo servicegroup attribute.attribute's keys follow:The ContainerOpts resource type attribute's definitions for project-aware typescontain the following values:■■RunInContainerWhen the value of the RunInContianer key is 1, only online agent function(entry point) for that resource runs inside of the project.When the value of the RunInContainer key is 0, the agent function (entry point)for that resource runs outside the local container (in the global environment).A limitation for the RunInContainer value is that only script agent functions(entry points) can run inside a container.PassCInfoWhen the value of the PassCInfo key is 1, the agent function receives thecontainer information that is defined in the service group’s ContainerInfoattribute. An example use of this value is to pass the name of the container tothe agent.
