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

The resources that the RAC framework resource group contains are described in Overview of the RAC Framework Resource Group. If the RAC framework resource group is created by using the scsetup utility, scsetup assigns names to the resources as listed in Table 2–3.

Table 2–3 Names Assigned to RAC Framework Resources by scsetup

Resource Type 

Resource Name 

SUNW.rac_svm

rac_svm

SUNW.rac_cvm

rac_cvm

SUNW.rac_hwraid

rac_hwraid

SUNW.rac_udlm

rac_udlm

SUNW.rac_framework

rac_framework

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

  2. Remove all RAC server resource groups in the cluster.

    These resource groups were created as explained in How to Register and Configure Oracle RAC Server Resources.

    Remove each RAC server resource group as follows:

    1. Disable each RAC server resource in the resource group.

      For each resource, type the following command:


      # scswitch -n -j resource
      -j resource

      Specifies the resource that you are disabling

    2. Remove each RAC server resource in the resource group.

      For each resource, type the following command:


      # scrgadm -r -j resource
      -j resource

      Specifies the resource that you are removing

    3. Remove the RAC server resource group.


      # scrgadm -r -g rac-server-rg
      -g rac-server-rg

      Specifies the resource group that you are removing

  3. Disable each resource that the RAC framework resource group contains.

    Disable the instance of the SUNW.rac_framework resource only after you have disabled all other resources that the RAC framework resource group contains. The other resources in the RAC framework resource group depend on SUNW.rac_framework.


    # scswitch -n -j resource
    -j resource

    Specifies the name of the resource that you are disabling. If this resource was created by using the scsetup utility, the name depends on the resource type as shown in Table 2–3.

  4. Remove each resource that you disabled in Step 3.

    Remove the instance of the SUNW.rac_framework resource only after you have removed all other resources that the RAC framework resource group contains. The other resources in the RAC framework resource group depend on SUNW.rac_framework.


    # scrgadm -r -j resource
    -j resource

    Specifies the name of the resource that you are removing. If this resource was created by using the scsetup utility, the name depends on the resource type as shown in Table 2–3.

  5. Unregister the resource type of each resource that you removed in Step 4.


    # scrgadm -r -t resource-type
    -t resource-type

    Specifies the name of the resource type that you are unregistering. This resource type was registered for the RAC framework resource group when the resource group was created. The resources that the RAC framework resource group contains are described in Overview of the RAC Framework Resource Group.

  6. Remove the RAC framework resource group.


    # scrgadm -r -g resource-group
    -g resource-group

    Specifies the name of the RAC framework resource group that you are removing. If this resource group was created by using the scsetup utility, the name of the resource group is rac-framework-rg.

Note –

After you have removed the RAC framework resource group, you must boot each cluster node in noncluster mode and uninstall the Sun Cluster Support for Oracle Real Application Clusters software packages. For more information, see How to Remove Sun Cluster Support for Oracle Real Application Clusters From a Cluster.

Example 2–6 Removing the RAC Framework Resource Group by Using the scrgadm Utility


# scswitch -n -j RAC1-rs
# scrgadm -r -j RAC1-rs
# scrgadm -r -g RAC1-rg
# scswitch -n -j RAC2-rs
# scrgadm -r -j RAC2-rs
# scrgadm -r -g RAC2-rg
# scswitch -n -j rac_svm
# scswitch -n -j rac_udlm
# scswitch -n -j rac_framework
# scrgadm -r -j rac_svm
# scrgadm -r -j rac_udlm
# scrgadm -r -j rac_framework
# scrgadm -r -t SUNW.rac_svm
# scrgadm -r -t SUNW.rac_udlm
# scrgadm -r -t SUNW.rac_framework
# scrgadm -r -g rac-framework-rg

This example shows the commands that are required to remove a RAC framework resource group that was created by using the scsetup utility. The resource groups RAC1-rg and RAC2-rg are RAC server resource groups that were created as shown in Example 2–1. The cluster from which this resource group is removed uses the Solaris Volume Manager for Sun Cluster.
