How to Create the RAC Framework Resource Group by Using the scrgadm Utility

1. On one node of the cluster, become superuser.

2. Create a scalable resource group.

   # scrgadm -a -g resource-group \   -y nodelist=nodelist \   -y maximum_primaries=num-in-list \   -y desired_primaries=num-in-list \   -y RG_mode=Scalable

   -g resource-group

   Specifies the name that you are assigning to the resource group.

   -y nodelist=nodelist

   Specifies a comma-separated list of cluster nodes on which Sun Cluster Support for Oracle Parallel Server/Real Application Clusters is to be enabled. The Sun Cluster Support for Oracle Parallel Server/Real Application Clusters software packages must be installed on each node in this list.

   -y maximum_primaries=num-in-list

   Specifies the number of nodes on which Sun Cluster Support for Oracle Parallel Server/Real Application Clusters is to be enabled. This number must equal the number of nodes in nodelist.

   -y desired_primaries=num-in-list

   Specifies the number of nodes on which Sun Cluster Support for Oracle Parallel Server/Real Application Clusters is to be enabled. This number must equal the number of nodes in nodelist.

   -y RG_mode=Scalable

   Specifies that the resource group is scalable.

3. Register the SUNW.rac_framework resource type.

   # scrgadm -a -t SUNW.rac_framework

4. Add an instance of the SUNW.rac_framework resource type to the resource group that you created in Step 2.

   # scrgadm -a -j fmwk-resource \   -g resource-group \   -t SUNW.rac_framework

   -j fmwk-resource

   Specifies the name that you are assigning to the SUNW.rac_framework resource.

   -g resource-group

   Specifies the resource group to which you are adding the resource. This resource group must be the resource group that you created in Step 2.

5. Register the SUNW.rac_udlm resource type.

   # scrgadm -a -t SUNW.rac_udlm

6. Add an instance of the SUNW.rac_udlm resource type to the resource group that you created in Step 2.

   Ensure that this instance depends on the SUNW.rac_framework resource that you created in Step 4.

   # scrgadm -a -j udlm-resource \   -g resource-group \   -t SUNW.rac_udlm \   -y resource_dependencies=fmwk-resource

   -j udlm-resource

   Specifies the name that you are assigning to the SUNW.rac_udlm resource.

   -g resource-group

   Specifies the resource group to which you are adding the resource. This resource group must be the resource group that you created in Step 2.

   -y resource_dependencies=fmwk-resource

   Specifies that this instance depends on the SUNW.rac_framework resource that you created in Step 4.

7. Register and add instances of the resource types that are required for the storage management scheme that you are using.

   • If you are using VxVM with the cluster feature, register and add an instance of the SUNW.rac_cvm resource type to the resource group that you created in Step 2.

     Ensure that this instance depends on the rac_framework resource that you created in Step 4.

     # scrgadm -a -t SUNW.rac_cvm

     # scrgadm -a -j cvm-resource \   -g resource-group \   -t SUNW.rac_cvm \   -y resource_dependencies=fmwk-resource

     -j cvm-resource

     Specifies the name that you are assigning to the SUNW.rac_cvm resource.

     -g resource-group

     Specifies the resource group to which you are adding the resource. This resource group must be the resource group that you created in Step 2.

     -y resource_dependencies=fmwk-resource

     Specifies that this instance depends on the SUNW.rac_framework resource that you created in Step 4.

   • If you are using hardware RAID support, register and add an instance of the SUNW.rac_hwraid resource type to the resource group that you created in Step 2.

     Ensure that this instance depends on the rac_framework resource that you created in Step 4.

     # scrgadm -a -t SUNW.rac_hwraid

     # scrgadm -a -j raid-resource \   -g resource-group \   -t SUNW.rac_hwraid \   -y resource_dependencies=fmwk-resource

     -j raid-resource

     Specifies the name that you are assigning to the SUNW.rac_hwraid resource.

     -g resource-group

     Specifies the resource group to which you are adding the resource. This resource group must be the resource group that you created in Step 2.

     -y resource_dependencies=fmwk-resource

     Specifies that this instance depends on the SUNW.rac_framework resource that you created in Step 4.

   • If you are using the cluster file system, no resource instance that represents this storage management scheme is required.

8. Bring the RAC framework resource group and its resources online.

   # scswitch -Z -g resource-group

   -Z

   Enables the resource and monitor, moves the resource group to the MANAGED state, and brings the resource group online

   -g resource-group

   Specifies that the resource group that you created in Step 2 is to be moved to the MANAGED state and brought online
