PRIMECLUSTER Global Disk Services Configuration and Administration Guide 4.1 (Solaris(TM) Operating System)

5.2.3.2 Cluster System Class Configuration

In cluster systems, specify [Type] and [Scope] in the Class Attributes Definition screen.

1. Setting [Type]

   Sets the class type.
   When creating a new disk class, selecting a physical disk that is not shared by other nodes from the [Physical Disk] field, sets the type to "local" by default.
   Selecting a shared physical disk, sets the type to "shared."

   
   

2. Displaying [Scope]

   Displays connecting nodes that can share a class.
   To change scope, click <Change Scope>.

   
   

3. <Change Scope> Button

   Changes nodes connecting to class.
   Click <Change Scope>, and Change Scope screen appears.

   [Figure: Change Scope Screen]

   

• Changing the checkbox in the [Change Scope] dialog box specifies the connecting node. (Multiple specification possible).

• Clicking < OK > of the [Change Scope] dialog box determines the class connecting node.

• Clicking <Cancel> of the [Change Scope] dialog box cancels the changing of the connecting node.

Class Resources

• In a cluster system, creating a class adds a class resource, and removing a class removes a resource.

• When removing a class resource, remove the class without using the PRIMECLUSTER cldelrsc(1M) command.

• Cluster applications that use resources of a class should be set after the volume configuration is complete.

For information on installation and initial setting of cluster systems, refer to "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide."
