Planning and Administering Data Services for Oracle^® Solaris Cluster 4.4

Disabling Resources and Moving Their Resource Group Into the UNMANAGED State

At times, you must bring a resource group into the UNMANAGED state before you perform an administrative procedure on it. Before you move a resource group into the UNMANAGED state, you must disable all of the resources that are part of the resource group and bring the resource group offline.

See the clresourcegroup(8CL) man page for additional information.

How to Disable a Resource and Move Its Resource Group Into the UNMANAGED State

You can also use the Oracle Solaris Cluster Manager browser interface to disable a resource and move a resource group into the unmanaged state. For Oracle Solaris Cluster Manager log-in instructions, see How to Access Oracle Solaris Cluster Manager in Administering an Oracle Solaris Cluster 4.4 Configuration.

Before You Begin

Ensure that you have the following information.

• The name of each resource to be disabled

• The name of the resource group to move into the UNMANAGED state

To determine the resource and resource group names that you need for this procedure, type:

# clresourcegroup show -v

1. On any cluster member, assume the root role that provides solaris.cluster.admin RBAC authorization.
2. Disable all resources in the resource group.

   # clresource disable [-n nodelist] -g resource-group +

   –n nodelist

   Specifies a comma-separated, ordered list of nodes on which to disable the resource.

   This list is optional. If you omit this list, the resource is disabled on all nodes in its resource group's node list.

   ---

   Note -  If you specify more than one node with the –n option, you can specify only one resource.

   ---

3. Switch the resource group offline.

   # clresourcegroup offline resource-group

   resource-group

   Specifies the name of the resource group to take offline.

4. Move the resource group into the UNMANAGED state.

   # clresourcegroup unmanage resource-group

   resource-group

   Specifies the name of the resource group to move into the UNMANAGED state.

5. Verify that the resources are disabled and that the resource group is in the UNMANAGED state.

   # clresourcegroup show resource-group

This example shows how to disable the resource (resource-1) and then move the resource group (resource-group-1) into the UNMANAGED state.

# clresource disable resource-1
# clresourcegroup offline resource-group-1
# clresourcegroup unmanage resource-group-1
# clresourcegroup show resource-group-1
