NAME | DESCRIPTION | SEE ALSO
The list below describes the resource group properties defined by Sun Cluster. RG_name is the only required resource group property, see description below.
This property controls whether the Resource Group Manager starts the resource group automatically when a new cluster is forming. The default is TRUE.
If set to TRUE, the Resource Group Manager attempts to start the resource group automatically to achieve Desired_primaries when all the nodes of the cluster are simultaneously rebooted.
If set to FALSE, the Resource Group does not start automatically when the cluster is rebooted. The resource group will remain offline until the first time that it is manually switched online using scswitch(1M) or the equivalent GUI command. After that, it will resume normal failover behavior.
True
Any time
The desired number of nodes that the group can run on simultaneously.
The default is 1. If the RG_mode property is Failover , the value of this property must be no greater than 1. If the RG_mode property is Scalable, a value greater than 1 is allowed.
1, see above
Any time
A Boolean value that indicates whether to recalculate the set of nodes where the group is online when the cluster membership changes. A recalculation can cause the RGM to bring the group offline on less preferred nodes and online on more preferred nodes.
False
Any time
Indicates whether cluster file systems are used by any resource in this resource group. Legal values that the administrator can specify are an asterisk (*) to indicate all global resources, and the empty string ("") to indicate no global resources.
All global resources
Any time
A Boolean value that indicates, when True , that the RGM should enforce implicit strong dependencies of non-network-address resources on network-address resources within the group. This means that the RGM starts all network-address resources before all other resources and stops network address resources after all other resources within the group. Network-address resources include the logical host name and shared address resource types.
In a scalable resource group, this property has no effect because a scalable resource group does not contain any network-address resources.
True
When disabled
The maximum number of nodes where the group might be online at once.
The default is 1. If the RG_mode property is Failover , the value of this property must be no greater than 1. If the RG_mode property is Scalable , a value greater than 1 is allowed.
1, see above
Any time
A comma-separated list of cluster nodes where the group can be brought online in order of preference. These nodes are known as the potential primaries or masters of the resource group.
The list of all cluster nodes in arbitrary order
Any time
A directory in the cluster file system that resources in the group can write essential administrative files in. Some resources might require this property. Make Pathprefix unique for each resource group.
The empty string
Any time
A non-negative integer value (in seconds) used by the RGM to determine where to bring the resource group online in the event of a reconfiguration or as the result of an scha_control giveover command or function being executed.
In the event of a reconfiguration, if the resource group fails to come online more than once within the past Pingpong_interval seconds on a particular node (because the resource's START or PRENET_START method exited non-zero or timed out), that node is considered ineligible to host the resource group and the RGM looks for another master.
If a call to a resource's scha_control command or function causes the resource group to be brought offline on a particular node within the past Pingpong_interval seconds, that node is ineligible to host the resource group as the result of a subsequent call to scha_control originating from another node.
3,600 (one hour)
Any time
The list of resources that are contained in the group. The administrator does not set this property directly. Rather, the RGM updates this property when the administrator adds or removes resources from the resource group.
The empty list
Never
A comma-separated list of resource groups that this group depends on. This list indicates a preferred order for bringing other groups online or offline on the same node. It has no effect if the groups are brought online on different nodes.
The empty list
Any time
A brief description of the resource group.
The empty list
Any time
The Solaris project name (see projects(1)) associated with the resource group. Use this property to apply Solaris resource management features such as CPU shares and resource pools to cluster data services. When the RGM brings resource groups online, it launches the related processes under this project name for resources that do not have the Resource_project_name property set (see r_properties(5)). The specified project name must exist in the projects database and the user root must be configured as a member of the named project (see projects(1) and System Administration Guide: Resource Management and Network Services).
This property is only supported starting in Solaris 9.
Changes to this property take effect after the resource has been restarted.
Name of the system default project
Any time
Any valid Solaris project name
Indicates whether the resource group is a failover or scalable group. If the value is Failover , the RGM sets the Maximum_primaries property of the group to 1 and restricts the resource group to being mastered by a single node.
If the value of this property is Scalable, the RGM allows the Maximum_primaries property to have a value greater than 1, meaning the group can be mastered by multiple nodes simultaneously.
Note: The RGM does not allow a resource whose Failover property is True to be added to a resource group whose RG_mode is Scalable.
Failover if Maximum_primaries is 1.
If Maximum_primaries is greater than 1.
Never
The name of the resource group. This property is required and must be unique within the cluster.
No Default
Never
Set by the RGM to Online, Offline, Pending_online, Pending_offline or Error_stop_failed to describe the state of the group on each cluster node. A group can also exist in an unmanaged state when it is not under the control of the RGM.
This property is not user configurable.
Offline
Never
